Si Mm: Sign-Of-Life Error In Safety Data; Si Mm: Brake Control Error - Siemens Sinamics S120 Diagnostic Manual

230625 <location>SI MM: Sign-of-life error in safety data
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-based "Safety Integrated" function on the Motor Module (MM) has detected an error in the sign-of-life of the
safety data between the Control Unit (CU) and MM and initiated a STOP A.
- there is either a DRIVE-CLiQ communication error or communication has failed.
- a time slice overflow of the safety software has occurred.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - select Safe Torque Off and de-select again.
- carry out a POWER ON (power off/on) for all components.
- 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.
- 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

230630 <location>SI MM: Brake control error
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-based "Safety Integrated" function on the Motor Module (MM) has detected a brake control error and initi-
ated a STOP A.
Fault value (r0949, interpret decimal):
10:
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 de-
activated)).
- Ground fault in brake cable.
30:
Fault in "close holding brake" operation.
- No brake connected or wire breakage (check whether brake releases for p1278 = 1 and p9602/p9802 = 0 (SBC de-
activated)).
- Short-circuit in brake winding.
40:
Fault in "brake closed" state.
60, 70:
Fault in the brake control circuit of the Control Unit or communication fault between the Control Unit and Motor Module
(brake control).
