4 Faults and alarms
4.2 List of faults and alarms
- check that the electrical cabinet design and cable routing are in compliance with EMC regulations (e.g. shield of the
motor cable and brake conductors are connected with the shield connecting plate and the motor connectors are
tightly screwed to the housing).
- replace the Motor Module involved.
Operation with Safe Brake Module:
- check the Safe Brake Module connection.
- replace the Safe Brake Module.
Operation with Safe Brake Module (SBA):
- check the SBA connection and if required, replace the SBA.

A07931 (F, N) Brake does not open
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: Motor
Reaction: NONE
Acknowledge: NONE
Cause: This alarm is output for r1229.4 = 1.
See also: p1216 (Motor holding brake opening time), r1229 (Motor holding brake status word)
Remedy: - check the functionality of the motor holding brake.
- check the feedback signal (p1223).
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
A07932 Brake does not close
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: Motor
Reaction: NONE
Acknowledge: NONE
Cause: This alarm is output for r1229.5 = 1.
For r1229.5 = 1, OFF1/OFF3 are suppressed to prevent the drive accelerating by a load that drives the motor -
whereby OFF2 remains effective.
See also: p1217 (Motor holding brake closing time), r1229 (Motor holding brake status word)
Remedy: - check the functionality of the motor holding brake.
- check the feedback signal (p1222).
F07934 (N) Drive: S120 Combi motor holding brake configuration
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A connected motor holding brake has been detected with an S120 Combi. However, this brake has not been
assigned to just one Combi feed drive and, therefore, brake control is not configured (correctly).
Fault value (r0949, interpret decimal):
0: No motor holding brake is assigned (p1215 = 0 or 3 on all S120 Combi feed drives).
1: More than one motor holding brake has been assigned (p1215 = 1 or 2 on more than one S120 Combi feed drive)
- or there is more than one DRIVE-CLiQ motor with motor holding brake.
