Cause : OverCurrent - comes when unwanted, unused, waste current flowing from a live conductor or terminal to the ground or earth through the ground conductor or any other conductive path.

Check the following:

1. Cable length limits must not be exceeded.
2. Motor cable and motor must have no short-circuits or earth faults
3. Motor parameters must match the motor in use
4. Value of stator resistance (P0350) must be correct
5. Motor must not be obstructed or overloaded
6. Increase the ramp time
7. Reduce the boost level
8. Connect a smaller motor (lower rating)

Remove fault and reset fault memory by disconnecting the

1. drive converter from the line supply and powering-up again
2. Press the Fn key on the BOP or AOP
3. Acknowledge fault P2103, P2104
4. P0952 (complete fault memory)

Cause

1. Short circuit at the output
2. Earth faults
3. Excessively large motor
4. Defective end stage
