Siemens SINAMICS S210 Operating Instructions Manual page 489

Cause: The "Safety Integrated" function integrated in the drive has identified a brake control fault in monitoring channel 2, and has
initiated STO.
- 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 deselect 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

F07935 Drive: Incorrect motor holding brake configuration
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: An incorrect motor holding brake configuration was detected.
Fault value (r0949, interpret decimal):
0:
A motor holding brake was detected where the brake control has not been configured (p1215 = 0).
The brake control configuration was set to "motor holding brake the same as sequence control" (p1215 = 1) (only when
commissioning for the first time).
1:
A motor holding brake was detected where the brake control has not been configured (p1215 = 0).
The brake control configuration was left at "No motor holding brake available" (p1215 = 0).
