Cause : Output current has exceeded internal fault limit.
1. Check motor load.
2. Check that the start-up data in parameter group 99 corresponds to the motor rating plate.
3. 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).
4. Check motor and motor cable (including phasing and delta/star connection).
5. If problem continue then check drive using multi-meter.
6. Check rectifier & IGBT using multimeter.
