Tips: Variable frequency drive hardware replacement precautions
- Replace the IGBT. Measure whether the resistance value of each road is balanced.
- Replace the drive board. Need to carefully check whether the plug and socket number is consistent.
- Replace the main control board. After replacing the main control board, set the application parameters, motor parameters and protection parameters of VFD.
- Replace the PG card. Check whether the terminals are normal. If the motor has a vibration or cannot rotate after replacing the card, need to exchange the A and B phase.
- Replace the communication board. Simply check the DIP switch set by VFD hardware station number, and then check that the communication light is normal.
- The communication board of some VFD series is an independent CPU. After the replacement, need to upload configuration program.
