Siemens SINAMICS S210 - Drive: S120 Combi Motor Holding Brake Configuration

Cause: The drive-integrated "Safety Integrated" function in monitoring channel 2 has detected a brake control error and initiated
a STOP A.
- OCC cable shield is not correctly connected.
- defect in the brake control circuit of the drive.
Fault value (r0949, interpret decimal):
10, 11:
Fault in "open holding brake" operation.
- brake not closed or interrupted cable.
- ground fault in brake cable.
20:
Fault in "brake open" state.
- short-circuit in brake winding.
30, 31:
Fault in "close holding brake" operation.
- brake not closed or interrupted cable.
- short-circuit in brake winding.
40:
Fault in "brake closed" state.
50:
Fault in the brake control of the drive or a communication error (brake control diagnostics).
Remedy: - select STO and then de-select again.
- check the motor holding brake connection.
- check the function of the motor holding brake.
- carry out a diagnostics routine for the faults involved.
- check for EMC-compliant control cabinet design and cable routing (e.g. shield OCC cable with shield terminal and shield
plate, check the connection of the brake conductors).
- replace drive.
Note:
OCC: One Cable Connection (one cable system)
SBC: Safe Brake Control
SI: Safety Integrated
STO: Safe Torque Off

F07934 (N) Drive: S120 Combi motor holding brake configuration
Message value: %1
Drive object: All objects
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.
2: Brake was accidentally assigned to the spindle (p1215 = 1); this is not permitted for this software release.
3: An attempt was made to enable the function "Safe brake control" (SBC, p9602 = p9802 = 1) for the spindle. This is not
permitted for this software release.
Remedy: Check whether the motor holding brake has been assigned to one S120 Combi feed drive exclusively (p1215 = 1 or 2).
The fault will only be withdrawn once the motor holding brake has been assigned to just one of the S120 Combi feed drives
(p1215 = 1 or 2 for this one drive). From this point, the motor holding brake will be controlled by this drive.
