F07404 Drive: Upper DC link voltage threshold reached
Message value: -
Drive object: All objects
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The DC link voltage monitoring is active (p1240 = 4, 6) and the upper DC link voltage threshold (p1244) was reached in
the "Operation" state.
Remedy: - check the line supply voltage.
- check the infeed unit or the Braking Module.
- increase the upper DC link voltage threshold (p1244).
- if necessary, deactivate the DC link voltage monitoring (p1240 = 0).
F07405 (N, A) Drive: Kinetic buffering minimum speed fallen below
Message value: -
Drive object: All objects
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: During kinetic buffering the speed fell below minimum speed (p1257 or p1297 for vector drives with U/f control) and the
line supply did not return.
Remedy: Check the speed threshold for the Vdc_min controller (kinetic buffering) (p1257, p1297).
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F07410 Drive: Current controller output limited
Message value: -
Drive object: All objects
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: The condition "I_act = 0 and Uq_set_1 longer than 16 ms at its limit" is present and can be caused by the following:
- motor not connected or motor contactor open.
- no DC link voltage present.
- Motor Module defective.
Remedy: - connect the motor or check the motor contactor.
- check the DC link voltage (r0070).
- check the Motor Module.
F07411 Drive: Flux controller output limited
Message value: -
Drive object: All objects
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: The specified flux setpoint cannot be reached, although the set maximum field current is specified (p1603).
- incorrect motor data.
- motor data and motor configuration (star-delta) do not match.
- the current limit has been set too low for the motor (p0640, p0323, p1603).
- induction motor (encoderless, open-loop controlled) in I2t limiting.
- the Motor Module is too small.
