SINAMICS S List Manual (LH1), 07/2007
A07927
DC brake active
Drive object:
SERVO, VECTOR
Reaction:
NONE
Acknowledge:
NONE
Cause:
The motor is braked using DC current - the DC current brake is active.
Remedy:
1) An alarm with alarm response DC brake is active.
The motor is braked with the DC braking current p1232 for the duration in p1233. If the standstill threshold p1226 is
fallen below, then braking is prematurely canceled.
2) The DC braking function was activated at Bico input p1230 for a set DC brake p1230=4.
Braking current p1232 should be impressed until the Bico activation is canceled again.
F07930
Drive: Brake control error
Drive object:
SERVO, VECTOR
Reaction:
OFF1 (NONE, OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The Control Unit has detected a brake control error.
- no motor holding brake connected.
- motor holding brake incorrectly parameterized (p1278).
- the motor holding brake control on the Motor Module is faulty.
- a DRIVE-CLiQ communications error has occurred between the Control Unit and the Motor Module involved.
Fault value (r0949, interpret decimal):
10: No brake connected or fault in the Motor Module brake control circuit ("open brake" operation).
11: Defect in the brake control circuit of the Motor Module ("brake open" operation).
20: Short-circuit in the brake winding or fault in the brake control circuit of the Motor Module ("brake open" state).
30: No brake connected, short-circuit in the brake winding or fault in the Motor Module brake control circuit ("close
brake" operation).
31: Defect in the brake control circuit of the Motor Module ("close brake" operation).
40: Defect in the brake control circuit of the Motor Module ("brake closed" state).
50: Defect in the brake control circuit of the Motor Module or communications fault between the Control Unit and the
Motor Module (brake control diagnostics).
See also: p1278 (Brake control, diagnostics evaluation)
Remedy:
- check the motor holding brake connection. If there is not motor holding brake, set p1215 to 0.
- check the parameterization of the motor holding brake (p1278).
- check the function of the motor holding brake.
- check whether there is a DRIVE-CLiQ communications error between the Control Unit and the Motor Module
involved and if required, carry out a diagnostics routine for the faults identified.
- check the electrical cabinet design and cable routing for EMC compliance
- replace the Motor Module involved.
- operation with Safe Brake Module: Check the connection of the Safe Brake Module.
- operation with Safe Brake Module: Replace the Safe Brake Module.

A07931 (F, N)
Brake does not open
Drive object:
SERVO, VECTOR
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
