Cause : Over Current fault.

Possible Causes
1. Motor power (P0307) does not correspond to the inverter power (r0206)
2. Motor leads are too long
3. Motor lead short circuit
4. Earth faults

Diagnose & Remedy

Check the following:
1. Motor power (P0307) must correspond to inverter power (r0206)
2. Cable length limits must not be exceeded
3. Motor cable and motor must have no short-circuits or earth faults
4. Motor parameters must match the motor in use
5. Value of stator resistance (P0350) must be correct
6. Motor must not be obstructed or overloaded
7. Increase the ramp time
8. Reduce the boost level (V/f control: P1311 & P1312
