The model of the CPU board kit is 6SR0900-0CB00-0AM0, and the weight is about 1.2KG. It is the most important board of the entire inverter.
The failure rate of the CPU motherboard is relatively low, accounting for about 20% of the total failure rate. Faults mostly occur in fault detection circuits and control terminal circuits. The maintenance of the fault detection circuit has become an important maintenance content of the CPU motherboard. When the fault detection circuit (subsequent circuit for voltage and current detection, temperature detection circuit) itself is damaged, the information will be wrong. It is clear that the main circuit is good, but an "output short circuit" fault or output phase failure is reported. It is obvious that the fan is OK, but reported overheating fault, etc., so that the inverter cannot be put into normal operation. The failure of the control terminal is mostly caused by the user mistakenly connecting the high voltage, which burns out the 24V power supply of the terminal, the open circuit of the terminal input circuit is damaged, and the input side circuit of the photocoupler is damaged. The damage rate of the CPU chip itself is less than 2%. Due to the technical blockade involved, the internal program is not easy to crack. General maintenance personnel do not have the relevant conditions to repair the chip, they can only purchase the original manufacturer's parts, or replace the CPU motherboard, so-called "board-level repair". But for the local damage of the CPU chip, you can try to repair it with alternative means.
The main features of the CPU board are as follows:
1. Intel Pentium MMX CPU 266 MHz
2. System memory: Two 144-pin SODIMM RAM slots support 8M-256MSDRAM memory
3. CompactFlash IDE interface disk for storage
4. Inverter control software
5. System program
6. Configuration file,
7. Built-in Ethernet controller: Intel SB82558/SB82559, RTL-8139; 10/100 Mbps
The CPU is also called the central processing unit. It is generally composed of arithmetic units, controllers, internal memory, input/input devices, interface circuits and buses. However, with the advancement and update of technology, its functions and structures are constantly expanding. It turns out that the peripheral circuits of the CPU are also integrated inside the device. Expand its hardware equipment to a certain scale, so that it can independently complete a more complex control function, this device is called a microprocessor. In the microprocessor family, in order to be suitable for a certain application field, it is different from general-purpose microprocessors (such as 80C51) in hardware composition, and has certain uniqueness. The microprocessor often used in the frequency converter has six PM wave output functions, which can realize specific control functions, and is also called a microcontroller.
