Cause:
During a flying restart, it was identified that the search current reached is too low.
It is possible that the motor is not connected.
Remedy:
Check the motor feeder cables.
F07331
Flying restart: Function not supported
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY
Cause:
It is not possible to power up with the motor rotating (no flying restart).
In the following cases, the "flying restart" function is not supported:
PMSM: operation with U/f characteristic and sensorless vector control.
Note:
PMSM: permanent-magnet synchronous motor
Remedy:
Deactivate the "flying restart" function (p1200 = 0).
F07332
Flying restart: maximum speed reduced
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY
Cause:
The maximum speed that can be reached is reduced; at very high speeds problems associated with the flying restart can
be encountered.
Possible causes:
- power ratio, power unit/motor too high
Remedy:
Parameter changes are not required.
Note:
A flying restart at speeds above 3000 rpm should be avoided.
A07352
Drive: Limit switch signals not plausible
Reaction:
NONE
Acknowledge:
NONE
Cause:
Limit switch signals are not plausible.
Possible causes:
- BICO interconnections are not OK (p3342, p3343).
- sensors are not supplying a valid signal (both supply a 0 signal).
Remedy:
- check the BICO interconnections for the limit switch signals.
- check the sensors.

A07353
Drive: DC quantity control deactivated
Reaction:
NONE
Acknowledge:
NONE
Cause:
The DC quantity control has deactivated itself.
The manipulated variable of the DC quantity control was at its limit.
Remedy:
Optimize the DC quantity controller (Kp, Tn, bandwidth, PT2 filter).
Note:
After changing the corresponding parameters, the DC quantity control is re-enabled and the alarm is automatically
withdrawn.

F07390
Drive: DC link capacitor forming fault
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
