Drive: S120 Combi Motor Holding Brake Configuration; Drv: Motor Holding Brake Detected - Siemens Sinamics S120 Diagnostic Manual

40: Fault in "brake closed" state.
50: Fault in the brake control circuit of the Control Unit or communication fault between Control Unit and Motor Module
(brake control diagnostics).
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.

207934 <location>Drive: S120 Combi motor holding brake configuration
Message value: %1
Drive object: All objects
Reaction: Servo: NONE (OFF1, OFF2, OFF3)
Infeed: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A connected motor holding brake has been detected with an S120 Combi unit. However, this motor holding 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 assigned (p1215 = 0 or 3 on all S120 Combi feed drives)
1: Multiple holding brakes assigned (p1215 = 1 or 2 on more than one S120 Combi feed drive)
MHB: Motor holding brake.
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The fault will only be withdrawn once the motor holding brake has been assigned to just one of the S120 Combi feed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.

207935 <location>Drv: Motor holding brake detected
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: A motor holding brake was detected where the brake control has not been configured (p1215 = 0). The brake control
configuration was then set to "motor holding brake the same as sequence control" (p1215 = 1).
Remedy: None necessary.
