F07411 Drive: Flux controller output limited
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: 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 larger power unit.
- check motor supply cable.
- check power unit.
- increase p0346.
A07416 Drive: Flux controller configuration
Reaction: NONE
Acknowledge: NONE
Cause: The configuration of the flux control (p1401) is contradictory.
Error IDs:
1 = Quick magnetizing (p1401 bit 6) for soft starting (p1401 bit 0)
3 = Quick magnetizing (p1401 bit 6) for Rs identification after restart (p0621 = 2)
Remedy: Re error ID 1:
- De-energize soft starting: p1401 Bit 0 = 0
- De-energize quick magnetizing: p1401 Bit 6 = 0
Re error ID 3:
- Re-parameterize Rs identification: p0621 = 0, 1
- De-energize quick magnetizing: p1401 Bit 6 = 0
F07426 (A) Technology controller actual value limited
Reaction: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The actual signal of the technology controller has reached its limit.
- Fault value = 1: upper limit reached
- Fault value = 2: lower limit reached
Remedy: - Adapt the limits in P2267, P2268 to the signal level.
- Scaling of the actual signal.

(Technology controller lower limit actual value)
A07427 Motor staging alarm
Reaction: NONE
Acknowledge: NONE
Cause: - Alarm value = 1: The technology controller is not active or is not being used to control the main setpoint (see p2251).
- Alarm value = 2: At least one external motor operating time limit has been exceeded.
Remedy: Alarm value = 1:
- enable technology controller (p2200)
- set technology controller mode p2251 = 0 (main setpoint)
Alarm value = 2:
- increase p2381, p2382 or set p2380 to zero.
