Cause : Short circuit comes when a short circuit within the motor itself or its connecting cables is a common culprit. This fault comes when internal components like the gate driver board or brake chopper IGBT can fail due to various reasons, leading to a short circuit fault.

1. Check motor and motor cable.

2. Check there are no power factor correction capacitors or surge absorbers in motor cable.

3. Remove motor cable then run drive , if fault not coming then drive ok,  run drive with another motor.
