Cause : Flux controller output limited comes when quick magnetizing is configured (p1401.6 = 1) the specified flux setpoint is not reached although 90% of the maximum current is specified.

- incorrect motor data.

- motor data and motor configuration (star-delta) do not match.

- the current limit has been set too low for the motor.

- induction motor (encoderless, open-loop controlled) in I2t limiting.

- power unit is too small.

- the magnetizing time is too short.

Remedy:

- correct the motor data. Perform motor data identification and rotating measurement.
- check the motor configuration.
- correct the current limits (p0640).
- reduce the induction motor load.
- if necessary, use a larger power unit.
- check motor supply cable.
- check power unit.
- increase p0346.
