Siemens SINAMICS S110 List Manual page 1113

Note:
The following causes may apply to fault values:
- motor cable is not shielded correctly.
- defect in control circuit of the Motor Module.
See also: p1278 (Brake control, diagnostics evaluation)
Remedy: - check the motor holding brake connection.
- check the function of the motor holding brake.
- check whether there is a DRIVE-CLiQ communication error between the Control Unit and the Motor Module
involved and, if required, carry out a diagnostics routine for the faults identified.
- 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 Modules 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: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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). It is also not permit-
ted to assign the brake to the spindle.
Fault value (r0949, decimal interpretation):
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.
