Cause : Output current has exceeded internal fault limit.

1. Check motor load.

2. Check acceleration times in parameter group

23 Speed reference ramp (speed control),

26 Torque reference chain(torque control) or

28 Frequency reference chain (frequency control).

3. Also check parameters

46.01 Speed scaling,

46.01 Speed scaling and

46.03 Torque scaling.

4. Check motor and motor cable (including phasing and delta/star connection).

5. Check that the start-up data in parameter group 99 corresponds to the motor rating plate.

6. Check that there are no power factor correction capacitors or surge absorbersin motor cable.

7. Check encoder cable (including phasing).
