Siemens SINAMICS G List Manual page 539

Cause: The safe standstill function has been selected on the control unit and is active.
Note:
This fault does not result in a safety stop response.
Remedy: None necessary.
Note:
CU: Control unit
SI: Safety Integrated
Reaction upon F: OFF2
Acknowledge IMMEDIATELY (power on)
upon F:
Reaction upon A: NONE
Acknowledge NONE
upon A:
F01625 SI CU: Sign-of-life error in safety data
Reaction: OFF2
Acknowledge: IMMEDIATELY (power on)
Cause: The Safety Integrated function on the control unit has detected an error in the sign-of-life of the safety data and ini-
tiated a STOP A.
- there is either a DRIVE-CLIQ communications error or communications have failed.
- a time slice overflow of the safety software has occurred.
Fault value (r0949, decimal):
Only for internal Siemens troubleshooting.
Remedy: - select safe standstill and then de-select again.
- carry-out a POWER ON (power off/on) for all components.
- 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.
- de-select all drive functions that are not absolutely necessary.
- reduce the number of drives.
- check the electrical cabinet design and cable routing for EMC compliance

CU: Control unit
SI: Safety Integrated
F01630 SI CU: Brake control defective
Reaction: OFF2
Acknowledge: IMMEDIATELY (power on)
Cause: The Safety Integrated function on the control unit has detected a brake control fault and initiated a STOP A.
- no motor holding brake connected.
- 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, 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).
Remedy: - check the motor holding brake connection.
- 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.
