4 Faults and alarms
4.2 List of faults and alarms
Fault value (r0949, interpret decimal):
10, 11:
Fault in "open holding brake" operation.
- parameter p1278 incorrectly set.
- no brake connected or wire breakage (check whether brake releases for p1278 = 1 and p9602/p9802 = 0 (SBC
deactivated)).
- ground fault in brake cable.
20:
Fault in "brake open" state.
- short-circuit in brake winding.
30, 31:
Fault in "close holding brake" operation.
- no brake connected or wire breakage (check whether brake releases for p1278 = 1 and p9602/p9802 = 0 (SBC
deactivated)).
- short-circuit in brake winding.
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 diagnostics).
Remedy: - check parameter p1278 (for SBC, only p1278 = 0 is permissible).
- select Safe Torque Off and de-select again.
- check the motor holding brake connection.
- check the function of the motor holding brake.
- check the Safe Brake Module connection.
- 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 Safe Brake Module.
- replace Power Module.
- replace the Control Unit.
Note:
SBC: Safe Brake Control
SI: Safety Integrated
A01631 (F, N) SI P1 (CU): motor holding brake/SBC configuration not practical
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: A configuration of motor holding brake and SBC was detected that is not practical.
The following configurations can result in this message:
- "No motor holding brake available" (p1215 = 0) and "SBC" enabled (p9602 = 1).
- "Motor holding brake just like the sequence control, connection via BICO" (p1215 = 3) and "SBC" enabled (p9602 =
1).
Note:
SBC: Safe Brake Control
Remedy: Check the parameterization of the motor holding brake and SBC and correct.

enable Safe Brake Control (processor 2))
