Acknowledge:
NONE
Cause:
The ON/OFF1 command is present (no 0 signal).
The command is either influenced via binector input p0840 (current CDS) or control word bit 0 via the master control.
Remedy:
Switch the signal via binector input p0840 (current CDS) or control word bit 0 via the master control to 0.
F07220 (N, A) Drive: Master control by PLC missing
Reaction:
OFF1 (NONE, OFF2, OFF3, STOP2)
Acknowledge:
IMMEDIATELY
Cause:
The "master control by PLC" signal was missing in operation.
- interconnection of the binector input for "master control by PLC" is incorrect (p0854).
- the higher-level control has withdrawn the "master control by PLC" signal.
- data transfer via the fieldbus (master/drive) was interrupted.
Remedy:
- check the interconnection of the binector input for "master control by PLC" (p0854).
- check the "master control by PLC" signal and, if required, switch in.
- check the data transfer via the fieldbus (master/drive).
Note:
If the drive should continue to operate after withdrawing "master control by PLC" then fault response must be
parameterized to NONE or the message type should be parameterized as alarm.
F07300 (A)
Drive: Line contactor feedback signal missing
Reaction:
OFF2 (NONE)
Acknowledge:
IMMEDIATELY
Cause:
- the line contactor was not able to be closed within the time in p0861.
- the line contactor was not able to be opened within the time in p0861.
- the line contactor dropped out during operation
- the line contactor has closed although the drive converter is switched off.
Remedy:
- check the setting of p0860.
- check the feedback circuit from the line contactor.
- increase the monitoring time in p0861.

F07311
Bypass motor switch
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
Fault value (r0949, interpret bitwise binary):
Bit 1: Switch "Closed" feedback signal missing.
Bit 2: Switch "Open" feedback signal missing.
Bit 3: Switch feedback signal too slow.
After switching, the system waits for the positive feedback signal. If the feedback signal is received later than the specified
time, then a fault trip (shutdown) is issued.
Bit 6: Drive switch feedback signal not consistent with the bypass state.
The drive switch is closed when switching-on or when switching-in the motor.

Remedy:
- check the transfer of the feedback signals.
- check the switch.
F07312
Bypass Line Side Switch:
Reaction:
