Cause : Output current is excessive due to load, wrong parameter or sensing problem in control card of drive and some time faulty motor. These are the step for fault correction :

1. Check motor load, due to motor overload drive generate fault.

2. Check motor data in drive parameter.

3. Check output current and compare with clamp-meter.

4. Check drive IGBT using multi-meter.

5. Check current sensing circuit in drive.
