4 Faults and alarms
4.2 List of faults and alarms
A07200
Drive: Master control ON command present
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Reaction:
NONE
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
Message class:
Communication error to the higher-level control system (9)
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- the higher-level control has withdrawn the "master control by PLC" signal.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
Message class:
Auxiliary unit faulted (20)
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.

F07320
Drive: Automatic restart interrupted
Message class:
Application/technological function faulted (17)
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
- the specified number of restart attempts (p1211) has been completely used up because within the monitoring time
(p1213) the faults were not able to be acknowledged. The number of restart attempts (p1211) is decremented at
each new start attempt.
- the monitoring time for the power unit has expired (p0857).
- when exiting commissioning or at the end of the motor identification routine or the speed controller optimization, the
drive unit is not automatically switched on again.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy:
- increase the number of restart attempts (p1211). The actual number of starting attempts is displayed in r1214.
- increase the delay time in p1212 and/or the monitoring time in p1213.
- either increase or disable the monitoring time of the power unit (p0857).
- reduce the delay time to reset the start counter (p1213[1]) so that fewer faults are registered in the time interval.
