What should we do when error SCP occurs? | Shihlin Electric

1. Disconnect the inverter with motor, then operate the inverter and see whether the SCP alarm still occurs. If not, please check whether the motor power cable and motor winding are short circuit or burned. 2. If the motor power cable and windings are normal, please check if the output of the inverter has a contactor. Please ensure the inverter switch only when there is no output. 3. If SCP alarm still occurs after disconnecting with the motor, please contact Shihlin for more details. Find quick answers in the Shihlin Electric FAQ—selection, wiring and troubleshooting for circuit breakers, magnetic contactors, AC drives, servo, HMI and PLC control.
