Si Motion Mm: Stop B Initiated; Si Motion Mm: Sbr Limit Exceeded - Siemens Sinamics S120 Diagnostic Manual

Remedy: - remove the cause to the fault on the Control Unit.
- check the value in p9357, if required, increase the value.
- check the shutdown path of the Control Unit (check DRIVE-CLiQ communication).
- carry out a diagnostics routine for message C30706.
- carry out a diagnostics routine for message C30714.
- carry out a diagnostics routine for message C30701.
- replace the Motor Module/Power Module
- replace Control Unit.
This message can only be acknowledged via the Terminal Module 54F (TM54F) or PROFIsafe.

SI: Safety Integrated
230701 <location>SI Motion MM: STOP B initiated
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF3
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP B (braking along the OFF3 ramp).
As a result of this fault, after the time parameterized in p9356 has expired, or the speed threshold parameterized in
p9360 has been undershot, message C30700 "SI Motion MM: STOP A initiated" is output.
Possible causes:
- stop request from the Control Unit.
- subsequent response to the message C30714 "SI Motion MM: Safely limited speed exceeded".
- subsequent response to the message C30711 "SI Motion MM: Defect in a monitoring channel".
Remedy: - remove the cause of the fault on the Control Unit
- carry out a diagnostics routine for message C01714.
- carry out a diagnostics routine for message C01711.
This message can only be acknowledged via the Terminal Module 54F (TM54F) or PROFIsafe.

SI: Safety Integrated
230706 <location>SI Motion MM: SBR limit exceeded
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Motion monitoring functions with encoder: SBR - Safe Acceleration Monitoring. After initiating STOP B (SS1) or STOP
C (SS2), the speed has exceeded the selected tolerance.
Encoderless motion monitoring function: SBR - Safe Brake Ramp Monitoring. After initiating STOP B (SS1) or SLS
changeover to the lower speed stage, the speed has exceeded the selected tolerance.
The drive is shut down by the message C30700 "SI Motion MM: STOP A initiated".
Remedy: Check the braking behavior and, if necessary, adapt the tolerance for the "Safe Acceleration Monitor" or modify the
parameter settings for the "safe brake ramp".
This message can only be acknowledged via the Terminal Module 54F (TM54F) or PROFIsafe.
