A5E36968571; GH180; NXGPRO; A5E32168144; 6SR0960-0CC16-0AD0 The signal conditioning board is a board outside the controller. This board is responsible for collecting signals such as the input voltage and current of the inverter and the output voltage and current. These signals are not adjusted. These collections The incoming signal is transmitted to the system interface card through the 37-core cable. The circuit on the system interface card performs range conversion, filtering and A/D conversion on the feedback signal, and the converted digital signal is transmitted to the processor. The sampling rate during A/D conversion varies from 3kHz to 6kHz, which is a function of the carrier frequency (also the switching frequency of the IGBT) and the number of "effective" units in the system. The digital modulation card generates a signal that controls the start of sampling for A/D conversion. Once the A/D conversion sampling is over, the system interface card generates an interrupt request to the CPU to start the motor line current, motor line voltage, input voltage, and input current calculation cycle. The card also contains one analog input signal and one solid state relay contact input signal. The relay contact signal is used to realize the emergency stop function of the inverter.
