Cause : Current limit - when the motor power rating does not correspond to the inverter power rating.

1. the motor power rating does not correspond to the inverter power rating

2. motor cables are too long

3. ground fault

Please check the following:

1. does the motor power rating (P0307) match the inverter power rating (r0206) ?

2. are the limit values for the cable lengths maintained ?

3. does the motor cable or motor have a short-circuit or ground fault ?

4. do the motor parameters correspond to those of the motor being used ?

5. stator resistance value (P0350) correct ?

6. is the motor overloaded or is the rotor locked (cannot rotate) ?

7. ramp-up time P1120 too low ?

Other Solutions :

1. Check whether the motor power corresponds to the inverter power

2. Check that the cable length limits have not been exceeded

3. Check motor cable and motor for short- circuits and earth faults4. Check whether the motor parameters correspond with the motor being used.

5. Check the stator resistance

6. Increase the ramp-up-time

7. Reduce the boost

8. Check whether the motor is obstructed or overloaded
