Cause : Over Current comes when the instantaneous drive output current has exceeded the over current threshold of the drive. This error cannot be reset until 10 s after it was initiated.

1. Increase time taken for the drive to accelerate/decelerate.
2. Check for short circuit on the output cabling.
3. Check integrity of the motor insulation using an insulation tester.
4. Check the motor cable length is within limits of the drive.
5. Reduce the value set in Current Loop Gain (P3.23).
