4 Faults and alarms
4.2 List of faults and alarms
40:
Fault in "brake closed" state.
50:
Fault in the brake control circuit of the Control Unit or communication fault between the Control Unit and Motor
Module (brake control).
80:
When using the Safe Brake Adapter (SBA), a fault has occurred in the brake control of the Control Unit.
See also: p1278 (Brake control diagnostics evaluation)
Remedy: - check the motor holding brake connection.
- for a parallel connection, check the setting of the power unit data set to control the holding brake (p7015).
- 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 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
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
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).
