Siemens SINAMICS G120XA - Flying Restart: Function Not Supported; Flying Restart: Maximum Speed Reduced; Drive: Limit Switch Signals Not Plausible; Drive: DC Quantity Control Deactivated

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withdrawn.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
