1. Check whether the three-phase output voltage and current of the inverter are balance. 2. Check whether the power cables of both motor and inverter are tightened or the motor has lost phase. 3. Change the operating frequency and check if it is a mechanical resonance situation. Find quick answers in the Shihlin Electric FAQ—selection, wiring and troubleshooting for circuit breakers, magnetic contactors, AC drives, servo, HMI and PLC control.
