8 SINAMICS PERFFECT HARMONY GH180 Catalog D 17

SINAMICS PERFECT HARMONY GH180 benefits

Clean input power

The SINAMICS PERFECT HARMONY GH180 drive:

• Meets the most stringent IEEE 519-2014 requirements for 

voltage and current harmonic distortion, even if the source 

capacity is no larger than the drive rating1):

– The SINAMICS PERFECT HARMONY GH180 drive is 

supplied with a minimum 18-pulse input with versions 

available up to 54-pulse input, resulting in less than 

3 percent total voltage distortion and less than 3 percent 

total current distortion. It eliminates the need for costly 

and inefficient harmonic filters and the associated 

resonance problems.

• Protects other online equipment from harmonic 

interference (computers, telephones and other power 

converters)

Sinusoidal output power (waveforms)

The SINAMICS PERFECT HARMONY GH180 drive:

• Minimizes drive induced torque pulsations and associated 

torsional analysis compared to other medium voltage 

topologies, by using a motor friendly pulse width 

modulation (PWM) output:

– Less than 1 % induced torque ripple for any given 

frequency results in no motor heating and no bearing 

wear

Note:

For certain motor voltages the torque ripple value can go 

up to 3 %, but only at relative speeds above 95 %. 

• Eliminates additional losses due to harmonics; thus, it can 

be used with new or existing motors without de-rating:

– Depending on configuration generates 13 to 33 level 

output waveform line to line

– Small output voltage steps produce no voltage spikes at 

the motor which allows the use of a motor with standard 

insulation 

– No need for filters up to 7500 ft (2.3 km)

– Waveforms remain high quality at lower speeds due to 

multi-level PWM output

1) IEEE 519-2014 compliance can only be guaranteed in networks 

without prior disturbances or harmonics already present.

Maximized availability

The SINAMICS PERFECT HARMONY GH180 drive:

• Remains operational in the event of a cell failure by using 

the cell bypass option which bypasses the faulted cell

• Achieves near 100 percent reliability and 99.99 percent 

availability, delivers greater productivity and a significantly 

reduced total cost of ownership over the drive’s life cycle

• Offers a Process Tolerant Protection Strategy (ProToPS™). 

ProToPS™ protects customer process from faulty sensors or 

data. Unlike typical systems that simply trip the drive and 

shut down the system due to a malfunction, it offers a 

proactive control approach based on a hierarchical warning 

system that allows the operator to evaluate the drive and 

system condition and respond appropriately or initiate 

controlled shutdown.

Extended reliability

The SINAMICS PERFECT HARMONY GH180 drive with an 

integrated transformer provides the following advantages:

• Protects drive semiconductors from line transients

• Completely protects the motor in case of a ground fault in 

the converter, the motor cabling or insulation

Exceptional input line performance

Robust design provides immunity from most input power 

disturbances and interruptions to insure protection of 

customer equipment and trip free operation during most 

common and frequent power quality issues: 

• Best in class input voltage brownout conditions - no trip 

down to 66 percent of nominal voltage. Output power is 

reduced by limiting the available motor torque, drive can 

operate continuously in this mode

• When the line voltage drops below 66 percent, it results in 

"Ride Through Mode / Power Loss Ride Through" of up to 

500 ms – 30 cycles @ 60 Hz and 25 cycles @ 50 Hz systems. 

(Not available for 4Q drives.)

• Built-in input transformer with lightning arrestors to 

provide protection from excessive peak voltage

Over 25 years of performance and more 

than 21,000 units in operation exceeding 

35 million kW installed power worldwide, 

Siemens has only one goal in mind: 

optimizing customer profitability

SINAMICS PERFECT HARMONY GH180 design

Drive topology

The SINAMICS PERFECT HARMONY GH180 series drives achieve 

an uncompromising performance by employing well-proven 

technology in a modular configuration, as shown in Figure 1. 

Medium voltage levels are obtained by adding together the 

outputs of multiple power cells. The power cells are simplified 

variations of standard 2-level PWM low voltage drives, which 

have been built in high volume for many years. 

Figure 1: Topology of SINAMICS PERFECT HARMONY GH180 drive 

(3 cells per phase)

For higher output voltage capabilities, the SINAMICS PERFECT 

HARMONY GH180 topology can be extended up to eight power 

cells in series in each phase, with additional secondary 

windings (number of secondaries equals number of power 

cells) on the integral isolation transformer.

Transformer

Since the early 1990s, Siemens has collaborated extensively 

with transformer suppliers to perfect the design of the 

transformers used in each SINAMICS PERFECT HARMONY

GH180 drive. The patented design provides several benefits 

in the drive topology, including the adaptability to input 

voltage, a multi-pulse input, and a reduction in common 

mode voltage.

The transformers used in the SINAMICS PERFECT HARMONY

GH180 are VPI dry-type, forced-air or water- cooled. They are 

designed specifically for use with a particular SINAMICS 

PERFECT HARMONY GH180 drive configuration and have 9 to 

24 extended delta secondaries. 

The SINAMICS PERFECT HARMONY GH180 transformers are 

designed, constructed, and tested as per IEC 60076-11 

standard. The transformer is an integral part of the drive that 

cannot be specified or obtained externally to Siemens.

Proven IGBTs

Low voltage Insulated Gate Bipolar Transistors (IGBTs) form 

the backbone of the SINAMICS PERFECT HARMONY GH180 

drive. Built in high volumes and serving as a proven power 

device across the industrial power control industry, IGBT 

technology has been in existence for more than two decades. 

The stability and availability of IGBTs give reliable, long-term, 

lifecycle confidence.

Linked power cells

In the SINAMICS PERFECT HARMONY GH180, power cells (see 

Figure 2) are linked together in series to build the medium 

voltage power output (see Figure 1) of the drive system. This 

modular configuration gives the SINAMICS PERFECT HARMONY

GH180 many advantages when it comes to maintenance, 

power quality and reliability. It also provides the basis for one 

of its most important advantages – increased availability 

through the advanced cell bypass option.

Figure 2: Schematic of a typical power cell

Advanced cell bypass

The SINAMICS PERFECT HARMONY GH180 is designed to 

withstand failures that would overwhelm conventional drives 

because redundancy options are added into the system. The 

patented, cell-based configuration maximizes uptime and 

simplifies modifications.

Through a redundant bypass control that is completely 

separated from each power cell, SINAMICS PERFECT 

HARMONY GH180 ensures automatic bypass of a failed power 

cell in 250 ms. The mechanical cell bypass option is 

implemented by providing a contactor at the output of each 

cell. One of the many benefits of mechanical cell bypass 

includes the ability to be tested during customer factory 

acceptance test. 

Since the cells in each phase are in series, bypassing a cell has 

no effect on the current capability of the drive, but the voltage 

capability will be reduced. Usually the required motor voltage 

is roughly proportional to frequency (speed). With a power cell 

or cells in bypass, the maximum speed the motor can operate 

at may be reduced approximately in line with the reduced 

voltage. The reduction in speed is somewhat load dependent.

SINAMICS PERFECT HARMONY GH180 Catalog D 17 11

It is important to maximize the motor voltage available after 

one or more cells have been bypassed. The following figures 

illustrate the voltage available from a SINAMICS PERFECT 

HARMONY GH180 drive, where the cells, represented by 

circles, are shown as simple voltage sources. Figure 3 shows a 

15-cell drive in which no cells are bypassed. With 100 % of the 

cells in use, 100 % of the original voltage is available. The 

voltage commands to the three phase groups of cells will have 

phase A displaced from phase B by 120°, and from phase C by 

120°.

Figure 3: Simplified diagram of a 15 cell drive

When two cells are bypassed in phase A, the output voltage 

will tend to become unbalanced, as illustrated in Figure 4 and 

not suitable for operating a motor.

Figure 4: Drive output with 2 cells bypassed in phase A

One possible remedy is to bypass an equal number of cells in 

all three phases, even though some may not have faulted. 

Figure 5 illustrates this approach. 

Obviously, this method prevents unbalance but sacrifices 

possible voltage capability. In this figure, 87 % of the cells are 

functional, but only 60 % are in use, and only 60 % of full 

voltage is available.

A better approach is illustrated in figure 6. This method takes 

advantage of the fact that the star-point of the cells is 

floating and is not connected to the ground. Therefore, the 

star-point can be shifted away from the motor neutral, and 

the phase angles of the cell voltages can be adjusted, so that 

a balanced set of motor voltages is obtained even though the 

cell group voltages are not balanced. Siemens calls this 

approach Neutral Shift (Siemens patented technology).

Figure 5: Drive output rebalanced by bypassing functional cells

In figure 6, the full remaining 87 % of functional cells are in 

use, and 80 % of the original voltage is available. The phase 

angles of the cell voltages have been adjusted so that phase A 

is displaced from phase B and from phase C by 132.5°, instead 

of the normal 120°.

Figure 6: Drive output rebalanced by adjusting phase angles 

(Neutral Shift)

The figure 7 below demonstrates the available output voltage 

after one cell is bypassed based on number of cells in 

configuration and bypass method used. For example, 

SINAMICS PERFECT HARMONY GH180 (3 cells per phase) with 

neutral point shift is capable to provide 83 % of output voltage 

compared to below 70 % for the drive with the same number 

of cell but without neutral point shift capability.

PERFECT HARMONY GH180 cell bypass evolution

The SINAMICS PERFECT HARMONY GH180 has revolutionized 

medium voltage power conversion. Perfect Harmony 

multilevel topology was invented by Robicon (now Siemens) in 

1994. Siemens continues to be the technology leader for 

multilevel topology inverters and has over 50 unique patents 

and 100 international patents filed around Perfect Harmony 

topology. In 2017 Siemens began releasing its 5th generation of 

SINAMICS PERFECT HARMONY GH180. The complete 5th

generation air-cooled range was released in 2021.

The SINAMICS PERFECT HARMONY GH180 drive continues to 

set industry standards for reliability and innovation. Siemens 

improves each generation in three key areas: increased 

reliability and availability, increased efficiency, and a smaller 

drive footprint. The innovation includes further improving cell 

bypass technology: evolving from an electronic thyristor based 

bypass (SCR) integrated to each cell to a mechanical bypass 

totally independent of the cell.

Cell bypass evolution

In the original concept as implemented 25 years ago, each cell 

contained a single phase rectifier bridge with a thyristor. The 

AC inputs of this rectifier bridge were connected to the cell 

output terminals. In the event of the failure bypass SCR is 

shorted effectively disconnecting the cell from the input 

power. Although this approach was effective under certain 

failure conditions, it had several drawbacks:

• Since cell and bypass share fiber optic communication, if it 

is lost, then the bypass can not be engaged because the 

control can not activate cell bypass due to the failed 

communications. Therefore, this bypass system is less 

effective and less reliable. 

• If there is any component failure in the cell such as IGBT, 

gate drive, cell control board power supply that may lead to 

bypass control malfunction resulting in the loss of the 

bypass functionality.

• To protect cell from exposure to fault current bypass 

circuitry had built-in fuse, that would automatically blow 

when cell bypass is engaged. If it was a nuisance trip 

customer could not automatically reset it which required a 

new cell for replacement.

In 2000, to overcome these difficulties, bypass was changed to 

an external mechanical contactor supplied from a completely 

independent power source and controlled by a separate 

control means. This contactor does not have to interrupt 

current, so it doesn’t need arc control measures. The contactor 

is a single pole double throw arrangement so that it can 

disconnect the cell from the output string and apply a shorted 

contact in place of the cell. With this bypass, the cells do not 

have to function at all for bypass to work.

Advantages of the mechanical cell bypass

• The SINAMICS PERFECT HARMONY GH180 bypass is based 

on traction DC contactor – proven and trusted technology!

• It does not matter which of the components has failed 

within the cell. In fact, even a failure in the fiber optic link 

that communicates to the cell can be detected and 

bypassed. This approach protects against the failure of any 

component in the power circuits or in the communications 

circuits, rather than protecting the drive against power 

semiconductor failure only.

• Mechanical bypass has separate communication with the 

drive control and independent regulated power supply to 

ensure maximum availability.

• In the instance of a nuisance trip customer can 

automatically reset bypass and continue the operation.

• During the fault, drive control performs a quick check to 

verify if the motor output voltage can be supported by the 

functional cells before a cell is bypassed. This voltage can be 

near the drive rated output voltage for a few seconds 

before dropping over time. If a cell is bypassed too fast, the 

remaining cells may not be able to support this voltage and 

leading to cells malfunction. SINAMICS PERFECT HARMONY

GH180 has built-in control function to perform all necessary 

checks to ensure safe and reliable operation.

• When a cell is bypassed, it allows for process ride through 

with an interruption of only 250 ms or less.

SINAMICS PERFECT HARMONY GH180 solutions

Drive heat load management

During operation, every drive generates heat that needs to be 

removed from the room to avoid equipment overheating. In 

many installations, it is very common to use air-conditioning to 

reduce the heat in the control room. The amount of heat 

dissipated into the room by the drive depends on the drive 

size, its running load, cooling method and efficiency. Other 

equipment located in the same space may also have losses 

requiring cooling. 

The more heat rejected into the room, the higher operational 

cost and total costs of ownership of the drive are. The drive 

typical losses are 3.0 to 3.5 % of the motor rating when 

operating at full load (losses reduce as load reduces). Air￾cooled drives usually dissipate heat directly into the room and 

require additional measures to keep operating within the 

manufacturer specified range; while water-cooled drives reject 

most of the losses into the water, less than 5% of losses are 

rejected into the room. 

The difference in cooling requirements for installations where 

heat rejected directly into the room could be 20 times higher 

compared to solution where losses are ducted outside the 

room. For example, 4000 Hp (3000 kW) drive losses in the 

room are 96 kW while the same drive with ducted air outside 

or heat exchanger (air-to-air or air-to-water), has only 4.8 kW 

losses resulting in significant reduction in cooling 

requirements. In this case heat losses in the room are similar 

to water-cooled drive performance. In order to reduce the 

requirement for air-conditioning of a control room, it is worth 

evaluating various heat management options available for air￾cooled drives:

• The air can be ducted directly outside (options M64 or 

M68) 

• Air-to-air heat exchanger (option W41) 

• Liquid-to-air heat exchanger 

Each approach has its own advantages and limitations and 

each case should be evaluated based on customer application, 

site conditions, availability of water, etc. Below are highlights 

of each option.

Ducting hot air outside is one of the most economical 

implementations but it does require upfront engineering from 

a customer. Engineering is required to design proper air flow in 

the room to avoid creating a vacuum or wind tunnel effect in 

the room. The air can be drawn either from outside with 

proper filtration to meet drive installation requirements or in 

some cases, HVAC is capable of supporting the necessary 

airflow. It is critical to design the solution properly to prevent 

unnecessary trips due to lack of air. The regular maintenance 

of outside filters is required to ensure that no contaminates 

get into the drive.

Utilization of heat exchangers creates close loop cooling 

systems. In close loop systems air is drawn through ventilation 

openings at the bottom or the front of the drive, depending on 

the product line, then circulated through the transformer and 

power cell sections and exhausted through the back of the 

drive enclosure. Warm air is cooled via the heat exchanger and 

circulated back to the drive. The hot and cooled air is 

transferred to the heat exchanger by duct work through the 

control room or power distribution center exterior wall. In case 

of liquid-to-air heat exchangers, heat is removed from the hot 

air and transferred to the customers' water system. 

There are two possible ways to implement this configuration 

the first one is similar to air-to-air heat exchanger set up where 

heat exchanger itself located outside and the hot air from the 

drive ducted. The second one is when the VFD blower cage 

assembly is replaced with the heat exchanger assembly. This 

solution does not require ducting work done to the building 

thus reducing additional engineering effort.

The heat exchanger option (either air-to-air or air-to-water) is 

a self-contained solution that does not require additional 

engineering on the customer's behalf. Compared to open loop 

systems, this solution provides higher degree of contamination 

protection due to the two separate airflow design, which keeps 

dirt, moisture, and other elements from getting into the 

equipment. 

Heat exchangers might require higher initial investment 

compared to open loop system or HVAC solution, it typically 

has the lowest total cost of ownership compared to traditional 

HVAC and a pay back of 2 to 3 years depending on size of the 

drive or solution saving operators cost of electricity for the 

next 17 years of the drive life.

Figure 8 Installation with air-to-air heat exchangers and two drives in 

the building

Not only this solution reduces overall cost of drive operation, 

the heat exchanger is also about 5 to 10 % more reliable 

compared to industrial redundant HVAC systems and about 20 

to 30 % more reliable compared to commercial HVAC systems. 

This reliability improvement is due to fewer components in the 

heat exchanger compared to HVAC system which consists of 

compressors, fans, belts, valves, etc. The above figures are 

based on the data collected by our field support team over 

past 10 years.

The air-to-air heat exchanger solution has built-in fan 

redundancy and comes complete with heat exchanger 

controls. It is rated for ambient temperatures from 32º F to 

104º F (0º C to 40º C). When required, they can be equipped 

with options to meet –40º F (–40º C) including space heaters, 

louvers and snow hoods for cold environments.

Bidirectional synchronous transfer 

There are two primary applications that require synchronous 

transfer:

• The first one is a drive used as a soft-starter to reduce 

stress from starting motors directly on line.

• The second one is used for process/flow control: starting up 

multiple motors and synchronizing them to the line 

according to process specifications. 

The key difference between these applications is sizing of the 

drive. When variable frequency drive (VFD) is used to start 

the motor in an unloaded condition, the VFD does not have 

to match the full rating of the motor. For example, a 

20,000HP motor may be started by a 5000HP VFD if the drive 

output can provide sufficient output current and develop 

enough motor torque to accelerate the motor up to full 

speed. In this instance, the VFD is at full power only for a very 

short period of time. The drive transfers a motor across the 

line after the motor is at full speed. In all cases the motor is 

started in either unloaded or partially loaded condition. 

The drive is often used in this application when incoming line 

is soft and cannot support the inrush current of the motor 

during starting. Sometimes, the incoming line is even too 

weak to support a reduced-voltage start even though inrush 

current is less it is still about 250% to 300% of the motor full 

load current rating. Starting motors with VFDs have the 

following benefits:

• Multiple starts per day

• Draws minimal inrush currents while starting, minimizing 

voltage drop and system electrical stress

• Reduces mechanical shock (starting torque is controlled at 

nominal levels)

For such applications the SINAMICS PERFECT HARMONY

GH180 has a function for single motor synchronous transfer 

option (L29) that does not require any PLC, it is done by the 

drive’s control and in most cases without need for an output 

reactor. 

For the second option, the drive is sized to run the motor full 

time. In a pumping station, the demand can change 

significantly within a day for the water and wastewater 

industry and seasonally for oil pipelines. One variable 

frequency drive can be used in combination with multiple 

motors to adjust the flow to meet the demand. In this case, 

the last pump is always run by VFD for flow and pressure 

control. 

Siemens can design your sync transfer system to suit your 

application. With standard, pre-configured systems that 

utilize our best-in-class VFD and motor control products, 

Siemens can provide a full spectrum of standard and flexible 

options.

Once the sync transfer system has been completely 

assembled, Siemens performs full power testing to ensure 

seamless integration and operation. Components are 

assembled and tested. The Sync Transfer Control System 

(STC) supports transfer of two to eight motors directly to or 

from a line source of power. The system is designed to handle 

induction motors or synchronous motors and connection of 

motors to a source the same as the drive or to an alternate 

source.

Figure 9: Switchgear and reactor lineup for 3 motor synchronous 

transfer application (for drive manufactured in the USA only)

Optimized synchronous transfer

The traditional synchronous transfer option uses output 

reactor for a bump-less closed transfer (figure 10). 

Connecting voltage source VFDs to a motor in parallel to the 

line (closed transfer) can result in excessive currents. The 

solution used to prevent such excessive currents has always 

been to add a reactor between the VFD output and the 

motor. 

Figure 10: Typical multi-motor synchronous transfer application with 

reactor

The advantage of this implementation is the ability to operate 

for periods of time in parallel with the line. This makes the 

transfer from the line to the VFD as smooth as possible. The 

limitation of this solution is higher initial capital cost, increase

of the losses within the drive system and reduced output 

voltage capability of the drive system. While the losses and 

voltage drop are negligible with regards to motor operation, 

the reactor losses require additional cooling. The cooling of 

these losses is either can be done by placing the reactor 

outside or increasing the HVAC capability of the cooling 

system. Regardless, the capital cost of including a reactor is 

considerable.

Due to increases in drive control processing power 

synchronous transfer can be optimized to eliminate the use of 

an output reactor. This optimized synchronous transfer can be 

applied to most motor drive applications.

Figure 11: Optimized multi-motor synchronous transfer 

The benefit of this approach is the ability to remove the 

reactor between the VFD and the motor, and the associated 

motor line contactor feedback to the SINAMICS PERFECT 

HARMONY GH180 VFD. Synchronous transfer of the motor to 

the line remains as a closed bump-less transfer.

The optimized synchronous transfer does differ during "down"

transfer. When the motor is transferred from the line back to 

VFD while it is still closed transfer, it will result in a step torque 

change to the motor but it has minimal impact on process. 

The magnitude of this step change is limited to the allowable 

torque. 

Optimized synchronous transfer of motor to line 

(up transfer)

Optimized synchronous transfer operates in the same manner 

as the traditional GH180 transfer operation with regards to 

"up" transfer so the same operational logic and application 

methods apply. The graph below shows the motor operation 

during an "up" transfer:

• The magenta waveform is the voltage magnitude as seen by 

the motor. 

• The blue waveform is the output voltage of the VFD. 

• The green waveform is motor current 

• The red waveform is the control voltage for the VFD’s 

output contactor

Figure 12: Optimized synchronous up transfer

As shown in the graph, there is no observable change in motor 

voltage or current. This means that there is no meaningful 

change in motor torque during an "up" transfer, and it is 

synchronized with the line phase and frequency.

Optimized synchronous transfer of motor to the VFD 

(down transfer)

Optimized synchronous transfer of the motor to the VFD 

operates almost identically to the traditional SINAMICS 

PERFECT HARMONY GH180 "down" transfer method. All 

existing logic which was used previously can be applied to the 

optimized synchronous transfer. 

The VFD output is connected in parallel with the motor. When 

the VFD senses the voltage on the output, it synchronizes with 

this voltage. Once synchronized, the VFD signals to open the 

motor’s line contactor. Once the motor’s line contactor opens, 

the VFD starts operation without waiting for the line contactor 

open signal.

The chart below is a capture of an optimized synchronous 

"down" transfer:

• The magenta waveform is the motor voltage magnitude

• The red waveform is the VFD output current 

• The blue waveform is VFD/Motor voltage

Figure 13: Optimized synchronous down transfer

The graph shows negligible effect of the zero torque state. 

During the time between the opening of the motor’s line 

contactor and the VFD starts operating the torque of the 

motor will be zero. During "down" transfer the SINAMICS 

PERFECT HARMONY GH180 uses sophisticated sensing to 

determine the state of the line contactor. This sensing will 

adapt automatically to the application. This approach prevents 

timing issues and greatly reduces the process impact caused by 

the brief zero torque state. 

Additional considerations

There are a few rare cases that require additional analysis 

before using optimized synchronous transfer solution: 

• excessive system short circuit current ratings:

– for smaller drives (40 to 70 A), the short circuit current at 

the drive’s input should not excessed 35 kA, 

– the short circuit current should not exceed 200 times of

the drive’s rated output current. 

– In these cases, a 1 % reactor is required.

• excessive torque variations during steady state operation, 

and 

• extremely low motor/load inertia, for example electrical 

submersible pump application.

If your site or load falls into this category, the optimized 

synchronous transfer may be modified to fit your application. 

If this is not possible, the traditional synchronous transfer 

remains available to ensure all applications have the 

opportunity to use synchronous transfer for bypass operation. 

Summary

The optimized synchronous transfer system allows for bypass 

operation without the need for an output reactor. 

• Optimized and traditional synchronous "up" transfers are 

equivalent with no interruption of motor torque. 

• Optimized synchronous transfer has a brief torque 

interruption during "down" transfer operation -

interruption is kept brief by an adaptive algorithm which 

senses contactor status via motor behavior

When selecting the synchronous transfer option, Siemens 

recommends that customers install motor protection relay 

(MPR). Once the motor is transferred directly on line, it is no 

longer protected by the VFD. In case of the multi motor 

synchronous transfer option (N18), Siemens integrates an MPR 

with associated CTs and PTs into the switchgear line-up. If 

switchgear is supplied by the customer (L20), it is customer 

responsibility to install the MPR.

For both options, Siemens provides a synchronous transfer 

controller with predefined and tested logic up to 8 motors and 

built-in HMI for display. The controller can be installed as a 

part of the line-up or separate in a control room depending on 

customer requirements. Siemens solution is the most flexible 

and provides support for the customers’ selection of 

switchgear and motor protection relay to ensure the best fit 

for their site and application.

Electrical Submersible Pump Application

Approximately 90% of all oil wells require some form of 

artificial lift to improve oil flow. Electrical Submersible Pump 

(ESP) is one of several methods used in the industry. Once the 

oil reservoir stops producing oil under free flow, electrical 

submersible pumps are used to pump the oil to the surface.

Historically, low voltage drives have dominated in ESP 

applications, but recently more and more end-users are 

considering and using medium voltage drives. An ESP is a 

centrifugal pump that is driven by a medium voltage electric 

motor that ranges from 1000 V to 6600 V. 

More often than not, ESPs are installed in remote locations. 

The power is more susceptible to disruptions from outages, 

poor voltage regulation, and transient voltage conditions. The 

design, operational and site constraints make these motors 

sensitive to the following conditions:

• Input line overvoltage and transient spikes

• High inrush torques

• High dv/dt 

• Torque pulsations 

One of the most common ESP motor and cable failures is 

short-circuited motors and cables. The reason for short circuit 

events is insulation break down. The LV drive solution, if not 

properly selected and engineered, may produce high output 

voltage spikes that lead to insulation break down of both cable 

and motor. The ESP failures have a very high cost. The total 

cost to an end-user of one ESP failure is about $154K. Below is 

the breakdown of the average cost associated with the 

onshore ESP operation:

• Average loss of revenue $60x200x7=$84K based on:

– Price per barrel - $60 (can be as high as $100 depends on 

market conditions); average oil production per well: 200 

bopd (barrels of oil per day) and average workover & 

waiting time: 7 days

– Average intervention cost is $20K (maybe higher 

depending on a cost and availability of a rig) and average 

equipment cost of $50K

SINAMICS PERFECT HARMONY GH180 provides the best 

solution for this application. Siemens has over 1000 units 

installed globally in this application alone. It offers inherent 

almost sinusoidal output voltage waveform, low harmonics 

and negligible torque pulsations:

• Less than 1% VFD induced torque ripple for any given 

frequency: no motor heating and no bearing wear

• 13 level output waveform line to line and small output 

voltage steps (1.3kV): no voltage spikes at the motor

• No need for filters up to 7500ft (2.3km)

• Waveforms remain high quality at lower speeds 

Figure 14: Output waveform

SINAMICS PERFECT HARMONY GH180 input configuration 

waveform:

• Meets the most stringent requirements for voltage and 

current harmonic distortion, even if the source capacity is 

no larger than the drive rating

• Less than 3 % total voltage distortion

• Less than 3 % total current distortion

Figure 15: GH180 input waveform (9-cell, 54-pulse)

In addition, the SINAMICS PERFECT HARMONY GH180 provides 

the following benefits compared to a LV solution: 

• No step-up transformer needed, the drive has direct 

feedback from the motor – output voltage ranging from 

1.8 kV up to 6.6 kV.

• No restriction on starting torque – 100 % of torque is 

available at 1.6 Hz speed – this would significantly reduce 

motor stress compared to kick start of LV drive.

• When pump gets stuck due to sediment collection, the 

drive can produce 150 % of rated torque required to free 

the motor or if additional effort is needed drive can engage 

"rocking" function to free the pump. 

• In locations that have frequent lightning storms, the drive 

offers standard distribution arrestors to provide protection 

to drive, cables and motor.

• Flexibility with simplified and optimized input voltages from 

480 V up to 13.8 kV (higher input voltages on request).

Torque during ride-through 

ESP applications typically operate in regions where momentary 

power interruptions occur. These momentary power 

interruptions cause a loss of input power feeding the drive. 

The drive will respond by entering a mode called ride-through. 

The VFD performance during the voltage sag tolerance and 

ride-through of momentary power loss depend on the amount 

of capacitance available in the DC link. The tolerance level 

varies from manufacturer to manufacturer and ranges from 

90% to 75% of nominal input voltage. 

At full speed, the SINAMICS PERFECT HARMONY GH180 

provides regular operation for dips down to 90% of nominal 

voltage. After that the drive output power is rolled-back 

linearly from 100% power at 90% of input voltage down to 50% 

power at 66% of nominal input voltage. Output power is 

reduced by limiting the available motor torque. The VFD can 

operate continuously in this mode. When the input voltage 

falls below 66%, then the power is quickly reduced to a slightly 

negative value (regenerative limit) (figure16). This limit forces 

the drive to absorb power from the motor and maintain the DC 

bus voltages in case the input voltage recovers during MV ride￾through. 

This typical ride-through action is the most effective drive 

response for most applications. However, some applications 

with very low system inertia and high loads are willing to 

sacrifice ride-through duration to maintain enough torque to 

prevent stopping the process. 

Figure 16: GH180 torque during input voltage sag and ride-through

ESPs have low system inertia and a high load. Losing torque, 

even for a short time, will cause the flow to stop and reverse 

direction. At this point, one must wait for the column of fluid 

to drain back through the pump and sediment to settle before 

restarting the pump. Once started, one must refill the column 

of fluid before production is restored. This all wastes energy 

and time resulting in less revenue. 

Given the cost of time and energy to restore production in ESP 

applications, it is more important to maintain the process 

through application of torque during a short power 

interruption than the ability to instantly reapply torque after 

an extended power interruption.

Solution

For applications such as ESPs, SINAMICS PERFECT HARMONY

GH180 drives implement a scheme which allows to maintain 

some torque for a short time during ride-through. The power 

for this torque is the power stored within the DC filter banks of 

the power cells.

During ride-through, drive will provide torque to hold a preset 

speed for up to 100 milliseconds (5 cycles). After this period, 

the drive returns to the original ride-through algorithm where 

a slight regenerative torque is applied, and motor flux is 

maintained until DC power is exhausted or line voltage returns.

Figure 17: Typical pump speed response during extended torque ride￾through

Summary

Extended torque ride through uses the energy stored in the DC 

filter capacitors to extend the torque available from the drive 

when a brief power interruption occurs. The benefits are:

• Enough torque is supplied to maintain minimum flow to 

prevent pump cavitation

• No reverse flow following momentary power outages

• No waiting for the column of fluid to drain sediment to 

settle before restarting 

• No wasted energy refilling the column of fluid before 

production begins

SINAMICS PERFECT HARMONY GH180 54-pulse solution

IEEE 519-2014, "Recommended Practices and Requirements 

for Harmonic Control in Electric Power Systems", is the 

standard for input harmonics in North America. It 

recommends limits for individual harmonics and total 

distortion. The goal is to limit harmonics at Point on a Public 

Power Supply System Coupling (Point of Common Coupling), 

defined as the utility/customer connection point, focusing on 

current distortion limits for the user and on voltage distortion 

limits for the supplying utility.

The primary reason for harmonic distortion is non-linear 

loads including but not limited to VFD. Such loads draw non￾sinusoidal currents from the power supply which, in turn, 

causes distortion in the voltage waveform at the point-of￾common coupling. This distortion may impact other 

customers by reducing system efficiency or adding additional 

stress for equipment connected to the same power supply.

Siemens traditional implementation has a proven record that 

the performance of an 18-pulse drive is within the limits of 

IEEE 519. Typically, a VFD with 9 cell configuration lowers 

harmonic distortion at its input by phase shifting its 

transformer windings. The windings (one per each phase) are 

shifted 20° apart to achieve 18 pulse. As shown in Figure 18, 

with an 18-pulse VFD input, the current THD is 3.5% — well 

below the 5% limit set forth by IEEE 519. Telephone 

Interference Factor (TIF) is 114.

Figure 18: Input current harmonics with an 18-pulse VFD

As Siemens continue to improve performance of the 

SINAMICS PERFECT HARMONY GH180, we further reduce 

input harmonics with the same number of windings. Siemens 

new standard solution is 54-pulse 9-cell configuration. Each 

cell in SINAMICS PERFECT HARMONY GH180 has 6 pulse 

rectifier that in the past was shifted in the group of three (see 

figure 19). In the new configuration each individual cell 

winding is shifted 6.6° apart (see figure 19) to achieve 54 

pulse rectification without additional hardware and does not 

affect the drive footprint. The new design offers more than 

15 % improvement in current distortion and more than 30 % 

in TIF compared to 18-pulse configuration. 

Figure 19: Example of transformer winding phase shifting

Example of harmonic spectrum of 54 pulse is represented in 

Figure 20, the data show THD of the current is 2.9 % and the 

TIF is 77. 

Figure 20: Input current harmonics with an 54-pulse VFD

IEEE 519-2014 defines levels for Total Current Demand 

Distortion (TDD(I)). Most manufacturers measure and show 

cumulative amount of harmonic distortion or Total Harmonic 

Current Distortion (THD(I)). IEEE requires distortion measured 

at 100% load, at this point THD(I) equals to TDD(I). The 

improvement in current waveforms is shown in Figure 21.

Figure 21: Input line current waveforms

An additional benefit of 54-pulse solution compared to 18-

and 24-pulse configurations is cancellation of higher order of 

harmonics. Typical harmonic cancelation based on number of 

pulses:

18-pulse: 5, 7, 11, and 13 

24-pulse: 5, 7, 11, 13, 17 and 19 

54-pulse: 5, 7, 11, 13, 17, 19, 23, 25, 29, 31…, 47 and 49

The harmonics measurements mentioned in this discussion 

are based on ideal steady state operation of the drive and 

assuming the power supply network is symmetrical and free 

from harmonics. In real world conditions, the supply 

networks or connected equipment never follow the ideal 

environment and therefore, the actual measured harmonics 

would not be exactly as calculated or simulated. Our 

theoretical analysis and simulations for 54 pulse design were 

completed and verified by actual field testing and data.

SINAMICS PERFECT HARMONY GH180 water-cooled drive

SINAMICS PERFECT HARMONY GH180 water-cooled drives 

are designed to provide output power from 4,000 HP to 

33,000 HP (3 to 24.6 MW) in a single channel and output 

voltages from 3.3 kV to 11.0 kV. The GH180 water-cooled 

drives are approved for manufacturing only from the USA 

(New Kensington) location.

To support critical high power applications, Siemens 

redesigned its SINAMICS PERFECT HARMONY GH180 water￾cooled drive to be 20 % more compact and more powerful 

with cell current rating of 1375 A. The streamlined design 

offers the same proven reliability and performance as before, 

but within a smaller footprint and additional configuration 

flexibility that makes it even more versatile. 

The result is a simplified system that’s composed solely of a 

transformer cabinet, cell cabinet and cooling cabinet. There’s 

less programming needed, and fewer components with fewer 

connections means maintenance time is minimized, too.

Reliability is improved by reducing the number of threaded 

fittings on the water-cooled VFDs and replacing long hoses 

with copper pipe. Every aspect of the drive is optimized to fit 

small spaces while remaining compatible with — and 

delivering superior reliability to — virtually every application. 

Built-in safety

The inherent benefit of the distributed power structure of the 

PERFECT HARMONY multi cell topology results in significantly 

reduced fault energy stored in the inverter section (equivalent 

of the low voltage drive) as compared to other available 

technologies. To provide additional protection, every 

SINAMICS PERFECT HARMONY GH180 water-cooled drive 

includes the Arc Detection System as a standard feature in 

power cells since its design in 2006. 

The inverter section consists of cells equipped with arc 

detection sensors and the control to communicate with the 

drive system. This communication is supported by the 

Advanced Protocol software. In the rare event of cell arcing, 

the Advanced Protocol will initiate the shutdown of the 

inverter within 20ms and the drive control will issue a trip 

signal to an external breaker. 

When combined with suitable fast acting circuit breakers on 

the input and output circuits, the SINAMICS PERFECT 

HARMONY GH180 VFD can be effectively disconnected from 

the input line and the motor in a short duration. 

Recommended total opening time of the circuit breaker must 

not exceed 80. The drive monitors the total opening time.

The purpose of Arc-Fault Detection is to minimize the impact 

of the arc by reducing the time needed to trip the circuit 

breaker and interrupt the fault. 

Advanced cooling cabinet option

Customers that require high level of monitoring and 

redundancy will benefit from advanced cooling cabinet option 

(W32). This option offers a larger cabinet to provide easier 

access to components and for easier maintenance. To support 

maintenance, the cabinet has a built-in hoist and rail system 

for changing the pumps. The pumps are equipped with two 

low-voltage variable speed drives for better motor control of 

the pumps which, in turn, increases the reliability, efficiency 

and life of the pumps. Automatic switchover between pumps 

will occur in the event of one of the pumps failure or loss of 

flow. The customer has the freedom to program pump cycling 

based on their system requirements. The advanced cabinet 

supports both air-to-water and liquid-to-liquid heat 

exchangers. 

There are several signals available for remote monitoring 

through customer SCADA or plant HMI to provide timely 

feedback on performance of the entire cooling system 

including external heat exchanger. Increased monitoring 

allows for advanced indication of coolant system issues 

before the drive control issues an alarm or trip. These signals 

include: 

• water level

• flow 

• conductivity

• pressure and temperature

• In addition to pump status, pump VFD status is also 

available for remote monitoring 

• individual fan monitoring/status of the external liquid-to-air 

heat exchanger.

Option descriptions

Availability options

Cell redundancy

Processes that cannot tolerate a reduction in drive power 

when one or more cells are in bypass should select the cell 

redundancy option. This option significantly increases drive 

availability when long intervals between services are required. 

This option is scalable depending on your process 

requirements. Cell Redundancy options require cell bypass.

Option Description

U13 One redundant cell per phase (for air cooling only)

Option U13 provides full output power with a bypassed 

cell in each phase. This option adds extra three cells to 

the drive (i.e. one cell per phase). 

Note: Option U13 requires cell bypass (U11) and redundant 

blower (M61). 

Not available for output voltages 6.6, 6.9, 7.2, 11 kV.

U21 N+1 cell redundancy (for water cooling only)

Option U21 provides rated power operation with one 

cell bypassed.

Note: Option U21 requires cell bypass option (U11) and 

redundant pump. Not available with all output 

voltages. For details, please contact your Siemens sales 

partner.

U22 N+2 cell redundancy (for water cooling only)

Option U22 provides rated power operation with two 

cells bypassed. 

Note: Option U22 requires cell bypass option (U11) and 

redundant pump. Not available with all output voltages.

For details, please contact your Siemens sales partner.

Option Description

U11 Advanced cell bypass

Cell bypass provides a higher level of system 

availability and process reliability. In less than a 

quarter of a second (250 ms), the drive can bypass 

failed cells and maintain a balanced output voltage. 

With one cell in bypass, the drive still produces 

sufficient voltage to allow the process to continue 

uninterrupted, and the quality of the voltage and the 

waveform remain virtually unchanged. 

To ensure the most reliability and availability, the VFD 

is equipped with mechanical cell bypass with 

independent power supply and control 

communication. This cell bypass can be tested and 

demonstrated during witness testing.

Loss of cells reduces the drive’s power capability; 

torque is reduced only when the drive’s power 

capability exceeds the designed limit. Faulted cells 

can be replaced at a convenient planned maintenance 

window.

For some applications with low load inertia, such as 

an ESP, during the cell bypass the speed may rapidly 

decelerate. In such applications where a process trip 

may be issued by the system control, use of manual 

cell bypass is recommended.

Manual cell bypass is configured in the drive 

operating system. When a cell fault occurs, the drive 

will trip on the cell fault. The user can reset the fault, 

which triggers a cell bypass, and can then proceed to 

re-start the drive. The reset can be done through 

plant HMI or SCADA.

Option Description

U10 Process Tolerant Protection Strategy - ProToPS™

With a proven record of 99.99 percent process uptime, 

ProToPS™ protects the customer process from faulty 

sensors or data. ProToPS™ offers a proactive control 

strategy for applications where failure avoidance is 

critical. It provides a hierarchical system of warnings in 

advance of potential drive system trip. This control 

strategy allows time for the operator to evaluate the 

situation and respond appropriately to avoid a system 

shutdown.

This option requires advanced cell bypass (option U11) 

and redundant blower (option M61) for maximum 

performance.

Option Description

M61 Redundant blower

To improve system availability, an additional blower is 

added to the air-cooled drive. If a blower fails, the 

cooling system is automatic switched over to 

redundant blower to ensure uninterrupted drive 

operation. A fan alarm fault will be annunciated. This 

prevents production down time or disruptions.

Option Description

L53 UPS for power supply of the control

In the instances where UPS back up for low voltage 

network is not available on site, the drive can be 

equipped with a UPS to maximize up time during low 

voltage power interruptions. The UPS provides back 

up power for the drive control and is configured for a 

buffer time of up to 8 min.

Note: Option L53 is available for 120 V or 220 V AC only.

Option Description

L85 Redundant control power (for water cooling only)

This option provides a second low voltage network 

control input with automatic switch over to prevent 

unnecessary interruptions and down time in case the 

first low voltage supply fails. This option includes UPS. 

Note: Option L85 is available for water-cooled drives only and 

requires an additional cabinet.

Safety options

Option Description

K86 Safe Torque Off (STO)

The option K86 provides an efficient electronically 

based "Safe Torque Off" (STO) sub function which can 

be easily integrated into a completed machine's Safe 

Torque Off safety function.

The safety related STO function is a mechanism for 

preventing the drive from unexpectedly starting 

according to EN 60204-1:2006/A1:2009, Section 5.4. 

The function is integrated in the drive and is 

independent of the converter operating functions. It 

is used in conjunction with a machine function – or in 

the case of a fault – to disconnect the torque￾generating energy feed to the motor in a safety￾related fashion. 

There are two independent switch-off signal paths, 

which are both failsafe (low-active). This ensures that 

when a component fails or a cable is interrupted, the 

system always goes into the safe state. 

The following points apply when the STO function is 

selected: 

• The motor cannot inadvertently start. 

• The torque-generating energy feed to the motor is 

safely interrupted because of the safety-related pulse 

cancellation. 

• VFD output is not electrically disconnected. 

The STO function is certified in accordance with 

IEC 61800-5-2 with a safety integrity level (SIL) of up 

to 3 with a hardware fault tolerance (HFT) of 1 as 

defined in IEC 61508. STO meets EN ISO 13849-1:2015 

Safety Category 3 Performance Level e.

Option Description

A76 System arc detection

To provide additional protection, the SINAMICS 

PERFECT HARMONY GH180 IQ drive has the arc

detection system option. Optical arc flash detection 

sensors are located in each power cell and transformer 

cabinet. In the rare arc fault event, the signal will be 

sent directly to the upstream protection device and 

the drive will de-energize as quickly as possible.

Option Description

M57 Arc resistant design 40 A to 430 A

Arc resistant option is designed to help minimize the 

risks associated with an arcing fault and provides 

increased protection of customers' personnel and

Door interlocks

SINAMICS PERFECT HARMONY GH180, 6SR5 drives are 

designed with bolted covers as a standard option. For 

customers that would like to have keyed access, there are 

4 types of mechanical interlocks available depending on 

customer preference. Safety closing/interlocking system is 

based on the key transfer system. 

Typically, the circuit breaker is opened, and a feeder earthed 

to release a key to the drive key exchange unit which in turn 

releases the keys to the cabinet bolted covers of the power 

section(s). This ensures that the drive is isolated from the 

input medium voltage and that the medium voltage is no 

longer present. The number of keys will depend on the 

number of cabinets.

Option Description

M08 Superior - mechanical door interlocks

M09 Kirk - mechanical door interlocks

M10 Castell - mechanical door interlocks

M38 Fortress - mechanical door interlocks

M46 INDAC - mechanical door interlocks

M12 Electrical door interlocks

The electrical door interlock system prevents access to 

the energized sections in the drive as long as 

hazardous voltages are present. This system also 

prevents the drive from being switched on until all 

doors of the energized sections in the drive are closed.

Note: GH180 air-cooled as a default is supplied with M09, 

Kirk key interlocks in North America or M12 electrical

door interlocks in Europe and China.

Option Description

N10 Prepared for input contactor 

Input contactor allows customers to isolate medium 

voltage drive for maintenance or repairs purposes 

without disconnecting primary protection. This option 

is recommended when multiple medium voltage drives 

are installed at the single site connected to common 

upstream protection. The benefit of an input contactor 

is that it is capable to break full current while input 

disconnect only can be opened after primary 

protection is opened.

Selecting this option will add switchgear to the drive 

on the side. When option N10 is chosen, the 

appropriate switchgear sizing is automatically selected 

based on the other drive parameters.

Note: The input contactor option is available when the 

primary input voltage is less than 7.2 kV.

Option Description

N13 Prepared for input circuit breaker

Input contactors are only available for input voltage up 

to 7200V. When input voltage exceeds this, a circuit 

breaker is an appropriate solution.

Selecting this option will add switchgear to the drive on

the side. When option N13 is chosen, the appropriate 

switchgear sizing is automatically selected based on 

the other drive parameters.

Option Description

N94 Grounding studs 

This option provides protective grounds to create an 

electrically safe work condition during maintenance. 

The ground studs will be installed in the following 

locations: Input and output power terminations and 

ground pads. The terminations will be equipped with a 

ball type ground stud. 

Note: Grounding cable and/or clamps are not included

Option Description

N44 Make-proof grounding switch at drive input 

With option N44, a grounding switch is installed at the 

drive input. The switch connects each phase to ground 

to prevent unexpected reconnections during 

maintenance. 

For safety reasons, the drive control locks the ground 

switch open (OFF) using electromagnetic interlocks 

until the drive input voltage is removed (OFF) and 

10 min have passed to allow the power cell capacitors

closed (ON). The control is integrated into the 

protection and monitoring circuit of the drive.

In the event of maintenance work on the drive, it must 

be ensured on the plant side that there is no external 

voltage present, e.g. auxiliary voltage for blowers, the 

cooling system, controller and closed-loop control and 

any external drive outputs.

an additional cabinet 

Option Description

N45 Make-proof grounding switch at drive output

With option N45, a grounding switch is installed at the 

drive output. Some applications (ex: gas turbines or 

permanent magnet motor) may regenerate and feed 

energy back to the drive. In such instances, a make￾proof grounding switch is recommended. The switch 

connects each phase to ground to prevent unexpected 

voltage during maintenance. 

For safety reasons, the drive control locks the ground 

switch open (OFF) using electromagnetic interlocks 

until the drive input voltage is removed (OFF) and 

10 min have passed to allow the power cell capacitors 

to discharge; only then can the ground switch be 

closed (ON). The control is integrated into the 

protection and monitoring circuit of the drive.

Note: This option for 9 cell air-cooled configuration requires 

an additional cabinet

Options N44 and/or N45 are recommended for 

applications within Europe.

front/rear

With these options, the drive is prepared for 

connection to an external exhaust air system, which 

shall connect to the front (M64) of the blower 

assembly or to the rear (M68) of it. Only one of the 

options per drive.

These options are applicable when the customer is 

providing external exhaust ducting to carry the hot 

air blowing out of the drive cabinet outside the 

room.

When configuring the exhaust air ducts for the drive 

ventilation system, it is essential to ensure that the 

air flow rates stipulated in the drive data sheets or 

drawings are observed. The pressure drop between 

the air inlet and the air outlet of the drive is 

different for different configurations. 

Note: The following requirements shall be met when

• Provide openings in the air duct to allow for the 

blowers’ maintenance.

• After fitting the air duct, the cabinet doors must 

still be able to be opened and closed for 

maintenance purposes.

This option can affect the values for sound pressure 

level depending on the design of the exhaust air 

system. For more details, please contact your 

Siemens sales partner.

Synchronous transfer options

Option Description

L29 Bidirectional synchronized transfer 

Option L29 provides the capability for synchronized, 

seamless transfer of the one motor to the line and take￾over of the motor from the line. Before connecting the 

motor to the line, the converter synchronizes the motor 

to the supply/utility voltage phase, frequency and 

amplitude. Most applications do not require output 

reactor. 

Output reactor should be considered when the 

following conditions are present:

• Excessive system short circuit current ratings 

• Excessive torque variations during steady state 

operation, and 

• Extremely low motor/load inertia

Note: The circuit-breakers/contactors are not included in the 

scope of delivery. A motor protection relay should also 

be considered in the bypass circuit by the customer.

Option Description

N17 Bidirectional synchronized transfer of one motor, 

switchgear provided by Siemens

Selecting this option, in addition to synchronous transfer 

control function, it will add switchgear to the drive

lineup. The appropriate switchgear is selected and 

sized automatically based on the drive parameters. 

Note: Reactor-less bidirectional synchronized transfer is 

default. Option L09 must be selected if requested by 

the customer.

A motor protection relay (MPR) is part of the scope 

and installed in the bypass circuit. Siemens integrates 

an MPR with associated CTs and PTs into the 

switchgear line-up. Customer is responsible for 

programing the MPR.

Option Description

L09 Output reactor

Depending upon the installation or application an 

output reactor may be required for bidirectional 

synchronized transfer. The output reactor decouples 

the converter output during the transfer process.

For air-cooled drives the output reactor cabinet can 

be ether included in the drive lineup with the same 

degree of protection as the drive or housed in a 

separate NEMA 3R/IP14 cabinet designed for outdoor 

installation.

For water-cooled units, the water-cooled reactor 

cabinet will be included in the drive lineup with IP 

protection same as power section of the drive.

Option Description

N18 Bidirectional synchronized transfer of multiple 

motors, switchgear provided by Siemens

With this option in addition to the Sync Transfer 

Control system, Siemens will add switchgear to the 

drive based on the number of motors handled by the 

drive and system setup. When option N18 is 

selected, the appropriate switchgear sizing is 

automatically selected based on the drive 

parameters. Siemens can provide switchgear based 

on the customer preferred manufacturer.

Note: When a customer selects synchronous transfer 

option Siemens recommends customers to install a

Option Description

L20 Bidirectional synchronized transfer of multiple 

motors, switchgear provided by customer

In the cases where the customer either has already 

all required switchgear or prefers to procure their 

own equipment, Siemens offers just the Sync Transfer 

Control system (STC) which provides for the 

synchronous transfer of two to eight motors directly 

to or from a line source of power. The system is 

designed to handle induction motors or synchronous 

motors and connection of motors to a source the 

same as the drive or to an alternate source. The STC 

has a local color HMI to support the configuration 

and status of the system. The STC can be mounted in 

the options cabinet, switchgear (if space available) or 

a separate enclosure. The synchronous transfer 

control logic can be demonstrated during the witness 

test.

Note: When customers select synchronous transfer option 

Siemens recommends customers to install motor 

protection relay (MPR). Once a motor is transferred 

directly on line it is no longer protected by the VFD.

Due to the use of a rotor with permanent magnets 

any rotation of the shaft will induce voltage on the 

motor terminals. This has several implications:

• Precautions must be taken to ensure there is no 

voltage induced on the motor terminals.

• Equipment such as Variable Frequency Drives (VFD) 

must be applied such that power flow back from 

the motor will not damage equipment.

• The selected VFD must be able to tolerate the 

highest possible voltage which could be generated 

by a spinning PM motor. This is especially 

important for ESPs which may backspin after 

shutdown or motors operated in overspeed

Option Description

N26 Synchronized pre-charge and transformer pre￾magnetization 

Remote locations with such weak lines where starting 

a large VFD can cause a voltage dip, synchronized pre￾charge and pre-magnetization of transformer option 

is recommended. The inrush current is reduced to 

only 1 to 2 per unit.

With option N26, the synchronized pre-charge option 

is configured and installed. It allows precharge of not 

only the DC-link capacitors in all power cells, but in 

addition, to build-up the input transformer flux in 

close phase relation with the incoming medium 

voltage feed; hence, minimizing the transformer 

inrush currents when the circuit-breaker is closed. 

When the synchronous pre-charge option is selected, 

a separate auxiliary voltage supply is required by 

others. 

This option is only available for water-cooled drives.

Note: It is the responsibility of the supplier of the auxiliary 

feed to ensure the voltage phase difference between 

the medium voltage feed and the auxiliary feed are 

within the +/-15 degrees tolerance and that there is 

the same frequency between the medium voltage 

input and precharge to allow proper operation of the 

synchronous precharge.

Options Requiring Customer Specific Input

Option Description

Y05 Customer-specific nameplate

As standard the nameplate shows the rated data of 

the drive under nominal conditions.

If data on the nameplate should be adapted to 

special ambient conditions (temperature, altitude) 

or should reflect special load conditions (e.g. 

derating because of operation at low frequency) the 

option Y05 must be selected.

Information to be supplied:

• Altitude

• Coolant temperature

• Rated voltages

• Rated current

• Rated power

Y10 Circuit diagrams with customer-specific description 

field

The circuit diagrams are given customer-specific 

headers. The data for the header must be specified 

in plain text (up to three lines of 45 characters per 

line).

Y15 Output filter

The filter is typically required when cable lengths at 

the drive output exceed 2.3 km (7500 ft). At such 

long distances, the effective switching frequency 

harmonics and sidebands may excite a cable 

resonance resulting in transmission line 

overvoltages at the motor terminals. 

This option may also be used to address EMI or 

dV/dt requirements. The filter effectively removes 

all frequency components above 2000 Hz in the 

drive output voltage. Because SINAMICS PERFECT 

HARMONY GH180 is already free of low-order 

output harmonics, the result is a nearly perfect 

sinusoidal output waveform.

Depending on the drive configuration, the filter may 

be located in transition cabinets. The filter 

components are dimensioned based on the 

continuous current rating of the power cells and 

maximum drive voltage. 

For more detailed information, please contact your

Siemens sales partner.

Y36 Customer-specific cabinet labels

Labels with customer-specific information are 

attached to the drive cabinets according to Siemens 

standard. The text and quantity of these labels need 

to be specified as plain text. As standard, the labels 

will be manufactured out of Formica, using black 

letters on a white background.

1) Torque response values are valid for drive without an output filter. Tuning may be required to achieve these values.

2) Approx. 0.3 % speed error is typical. Worst-case speed error is equal to approximately 30 % of rated motor slip.

3) 0.1 % can be achieved with a 1024 PPR encoder. Speed accuracy depends on the encoder PPR. 

4) For specific applications, 0.01 % accuracy can be achieved – contact your Siemens sales partner.

5) Speed response numbers apply as long as torque limit is not reached.

6) Testing is required to determine exact value.

Note: Applications that require lower than 1 % speed operation under high load torque should use the CLVC mode. In such cases it 

is preferable to select a motor that has high full-load slip (> 1.0 %) and high breakdown torque.

Voltage sag, undervoltage conditions and interruptions performance

At full speed, SINAMICS PERFECT HARMONY GH180 provides 

regular operation for dips down to 90% of nominal voltage. 

After that the drive output power is rolled-back linearly from 

100 % power at 90 % of input voltage down to 50 % power at 

66 % of nominal input voltage. Output power is reduced by 

limiting the available motor torque. The drive can operate 

continuously in this mode. 

When the input voltage falls below 66 %, then the power is 

quickly reduced to a slightly negative value (regenerative 

limit, see Figure 22). This limit forces the drive to absorb 

power from the motor and maintain the DC bus voltages in 

case the input voltage recovers during medium voltage ride￾through. The limit is implemented as an inverse function of 

speed in order to maintain constant power flow to the DC￾bus.

Figure 22: Drive power (Pmax) as a function of input voltage 

magnitude (Erms)

When the input voltage falls below 66 % (or other limit 

defined by manufacturer), the drive will ride-through without 

tripping up to 500 milliseconds with all cells functioning and 

100 milliseconds with cells in bypass. During ride-through 

the motor voltage is maintained but no torque is produced 

until the input voltage is re-established. The drive provides 

only magnetizing current to a motor leaving energy stored in 

the DC link to generate output voltage. Automatic restart 

into spinning load is possible with no load or line disturbance 

as long as the motor flux is present. 

SINAMICS PERFECT HARMONY GH180 requires a separate low 

voltage input for control and auxiliaries provided by the 

customer that is typically backed up by UPS. In the case 

where a UPS is not available the GH180 drive has the option 

to incorporate a UPS into the drive design to ensure smooth 

performance during voltage sag and undervoltage conditions 

for low voltage network. Without UPS, the SINAMICS 

PERFECT HARMONY GH180 control ride-through is 5 cycles. 

Applications with very low inertia like ESP might come to a 

complete stop during power loss ride-through and require 

either automatic or manual restart depending on operator 

preferences.

according to customer application and specification. They 

can be selected from more than 200 parameters and 

variables available in the system. The table below shows 

some of the parameters available.

• First 4 synchronized to operator panel display

• Fault and alarm indicators (traffic lights: red = fault, 

yellow = alarm, green = none)

Drive Tool

Its purpose is to manage all of the drive features and provide 

the user with a user-friendly view of the drive. The Drive 

Tool's main features include:

• Drive configuration

• Drive variable graphing

• Drive status (provides real time status of various 

parameters, measured values, and calculations)

Debug Tool

This application provides a remote graphical user interface. 

With the Debug Tool, the user can examine drive variables 

using a PC in a simple and quick manner. The debug utility is 

intended for use during test, commissioning, and 

troubleshooting of the drive.

SOP Utilities

The System Operating Program (SOP) is the logic that maps 

the internal and external I/O into the functionality of the 

drive. In its simplest form, it just maps internal states to 

external points. It performs most of the functionality on the 

PC running the ToolSuite, it also offers serial communications 

capability for uploading and downloading the System 

Program directly to the drive via an Ethernet interface 

between the drive and the PC.

Protection and monitoring functions

Vector control The drive can be controlled by means of vector control algorithm without an encoder: open-loop 

control (standard) or with it: closed-loop control (option).

Auto tuning Auto tuning is available to optimize the control performance of the drive.

Automatic restart Automatic restart is a custom feature used to purposely restart and restore the drive operation 

after a power failure or power removal. When Automatic Restart function is specified by the 

customer, qualified Siemens personnel must configure and ensure the function executes as 

specified.

Energy saver Energy saver control allows the reduction of motor losses, and improves overall efficiency, when 

the demanded motor load is low. Depending on the motor load, the control will reduce motor 

flux.

As motor load increases, the control will increase motor flux.

Flying restart The flying restart function permits smooth connection of the drive to a rotating motor.

Diagnostics functions • Self-diagnosis of control hardware

• Non-volatile memory for reliable diagnosis when the power supply fails

• Monitoring of IGBTs with individual messages for each cell

The amount of time that the drive was operational since it was commissioned can be displayed. 

The switching cycle counter can be generated by means of an event log from the drive controller.

Detection of actual motor 

speed

The control algorithm calculates actual motor speed from currents and voltages measured at the 

drive output.

Emergency stop button The drives are equipped as standard with an Emergency Stop button (red mushroom button with 

yellow collar) which is fitted in the cabinet door. The contacts of the pushbutton are connected 

in parallel to the terminal block so they can be integrated in a protection concept on the plant 

side.

Ground fault protection An optional output signal can be provided to operate the customer protection.

I/O monitoring I/O signals allow user customization of the system and they can be monitored remotely or by 

using the operator panel display.

Thermal overload protection Based on the output signals of the drive, the thermal motor model is calculated. The motor 

thermal overload protection algorithm prevents the motor from being exposed to excessive 

temperatures.

Air cooling requirements

Power losses of drive system

Traditional way to publish heat losses for a VFD is based on the drive's efficiency – heat rejection of the drive itself or 

kW.PowerLoss = (100 % – DriveEfficiency) x kW.DrivePower

The limitation of this approach is incorrect sizing of the VFD at full load resulting in less current required by the motor – potentially 

starving the motor at full load. That is why Siemens uses system approach and includes not only VFD efficiency but also motor 

efficiency when calculating losses for the drive: 

kW.PowerLoss = kW.Input – kW.Output 

This ensures that a customer can not only get properly size HVAC but also properly sized drive. Typical motor efficiency used to 

calculate heat losses in the tables below is 95.2 %.

Air-cooled drives rely on circulating air to cool the components within the drive. The amount of heat generated is equivalent to the 

drive losses. As the drives take in as much air as is output, no building make-up air is required unless the drive has the option "drive

prepared for duct flange connection" (M64 or M68), in this instance depending on your site and building configuration, Siemens will 

provide the required airflow and pressure drop to ensure proper drive function.

Water cooling requirements

Drive with integral liquid-to-liquid heat exchanger

SINAMICS PERFECT HARMONY GH180 6SR327 as a default is 

offered with an integral plate and frame heat exchanger. This 

heat exchanger consists of a series of thin, corrugated plates, 

spaced with rubber gaskets, to transfer heat between two 

fluids. This type of heat exchanger is very efficient because 

the fluids are exposed to the entire surface area of the plates. 

This is the best option if customer has water available on site.

Liquid-to-liquid heat exchanger data:

• Made of stainless steel alloy 304 or 316. 

• Customer inlet water temperature: 32 - 104F (0-40C)

• Heat exchanger design pressure – 150 psi (1034.2 kPa)

The raw water must be chemically neutral, clean and free of 

solids. Additional specifications relating to the quality of the 

raw water are listed in the following table.

In case of deviations it is recommended to carry out an 

analysis of the water in order to ensure the heat exchanger's 

endurance strength. If the water is supplied from a lake or 

river, W55 option is recommended for 6SR327 – prepare for 

inlet water filter or specify a shell and tube heat exchanger. 

This is a drop ship option. 

Customer Water Connections Interface: customer is 

responsible for water connection to the drive:

• SINAMICS PERFECT HARMONY GH180 6SR327 - 2” ANSI 

flange (DIN 50 flange) 

Cold Side Flow Requirements for GH180 6SR327 with integral 

liquid-to-liquid heat exchanger:

• 9 cell – 100 GPM (378.5 LPM)

• 12 cell – 150 GPM (567.8 LPM)

• 15 cell – 200 GPM (757.1 LPM)

• 18 cell – 225 GPM (851.7 LPM)

• 24 cell – 275 GPM (1,041 LPM)

Example of an integral liquid-to-liquid heat exchanger:

Variable Specified value 

Grain size of any entrained

parts 

< 0.5 mm 

pH value 6.5 to 8.0 

Carbonate hardness < 0.9 mMol/l (5 °dH) 

Total hardness < 1.7 mMol/l (9.5 °dH)

Chlorides < 60 mg/l 

Sulfates < 80 mg/l 

Nitrates < 10 mg/l 

Iron (Fe) < 0.2 mg/l 

Ammonia < 10 mg/l

Dissolved substances < 3.4 mMol/l (340 ppm)

Drive prepared for liquid-to-air heat exchanger 

When water is not available on site SINAMICS PERFECT 

HARMONY GH180 6SR327 has an option to be installed with 

external liquid-to-air heat exchanger (W32). In this case, 

integral heat exchanger is removed from the circuit and 

replace with set up to directly connect to external heat 

exchanger. 

In this set up the coolant flows through the system, collecting 

the heat that has dissipated from the power cells and 

transformer, and then exits the drive, passing through the 

heat exchanger. As the coolant passes through the external 

tubing (coil) of the heat exchanger, it is cooled by a network 

of blowers, blowing cooler air onto the coils and reducing its 

temperature by means of forced convection. 

Each heat exchanger fan motor has a non-fused disconnect 

mounted on the heat exchanger unit. The contactors for each 

of the fans are located inside the converter heat exchanger 

control panel. A separate auxiliary feed is required to the 

converter that powers all of the contactors.

The heat exchanger is designed to operate with standard 

capacity fans. There are several options available for heat 

exchanger: additional capacity (N+1) as an option and the 

heat exchanger copper coil can be coated with Heresite to 

protect the cooling coils from corrosion. It can be designed to 

be vertical or horizontal air flow. Shown below is a horizontal 

heat exchanger design and its installation.

Below is an example of the flow diagram: 

6SR327 with W32 Option flow requirement:

The flow rate depends on customer site and conditions - it is 

impacted by installation distance, size of the pipe and other 

conditions. As long as the pressure drop external to the VFD 

coolant cabinet is less than 15 psi (103.4 kPA) and the heat 

exchanger is at or below the VFD elevation, the coolant 

system should operate as designed. 

Customer Water Connections Interface: customer is 

responsible for water connection to the drive

• GH180 6SR327 W32 – 3" ANSI flange (DIN 80 flange) 

When installing external heat exchanger, it is recommended 

to evaluate if you need freeze protection. When freeze 

protection is not required 100 % deionized water is 

recommended. If freeze protection is required glycol should 

be limited to the range of 25 to 60 % by volume. 

Freezing point of coolant % Propylene glycol by 

volume (by mass)

+10 °F / –12.2 °C 25 (25) 

0 °F / –17.8 °C 32 (33)

–10 °F / –23.3 °C 39 (40)

–20 °F / –28.9 °C 44 (45)

–30 °F / –34.4 °C 48 (49)

–40 °F / –40.0 °C 52 (53)

–50 °F / –45.6 °C 55 (56)

–55 °F / –48.0 °C 60 (62)

The volume of coolant required for the drive is approximately 

100 U.S gallons. To determine the total system volume, the 

volume in the piping to and from the main heat exchanger 

and the volume of the main heat exchanger must be 

determined by the customer. A drive in the system with total 

volume < 250 U.S. gallons can operate with one coolant 

expansion tank. A drive in a system with total volume 

between 250 and 500 U.S. gallons requires one high capacity 

coolant expansion tank.
