4.16 Quick magnetization for induction motors
The flux control configuration (p1401) settings are inconsistent.
Fault codes:
1 = quick magnetization (p1401.6) and smooth starting (p1401.0)
2 = quick magnetization (p1401.6) and flux build-up control (p1401.2)
3 = quick magnetization (p1401.6) and Rs identification (stator resistance identification) after
restart (p0621 = 2)
Remedy:
● For fault cause 1:
● For fault cause 2:
● For fault cause 3:
Flux controller output limited
If the current limit p0640[D] is set very low (below the rated magnetization current value in
p0320[M]), the parameterized flux setpoint p1570 [D] might not be reached at all.
As soon as the time in p0346 (magnetization time) is exceeded, fault F07411 is output.
Generally, the magnetization time is significantly longer than the flux build-up time
associated with quick magnetization.
Reaction: OFF2
Acknowledgement: Immediately
Cause:
With quick magnetization configured (p1401.6 = 1), the specified flux setpoint is not reached
even though the current setpoint = 90 % of maximum current.
● Motor data are incorrect.
● Motor data and motor connection type (star/delta) do not match.
● Current limit in p0640 is set too low for the motor concerned.
● Induction motor (encoderless, open-loop control) at I2t limit.
● Motor Module rating is too low.
Remedy:
● Correct the motor data.
● Check the motor connection type.
● Correct the current limits (p0640, p0323).
● Reduce the load on the induction motor.

– Deactivate smooth starting: p1401.0 = 0
– Deactivate quick magnetization: p1401.6 = 0
– Deactivate flux build-up control: p1401.2 = 0
– Deactivate quick magnetization: p1401.6 = 0
– Change Rs identification parameter settings: p0621 = 0, 1
– Deactivate quick magnetization: p1401.6 = 0
