Si Motion Cu: Stop B Initiated; Si Motion Cu: Sbr Limit Undershot - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
Remedy: - remove the cause of the fault on the second monitoring channel
- carry out a diagnostics routine for message C01706.
- carry out a diagnostics routine for message C01714.
- carry out a diagnostics routine for message C01701.
- check the value in p9557 (where available), increase the value if necessary, and carry out a POWER ON
- check the shutdown path of the Control Unit (check DRIVE-CLiQ communication if it has been implemented)
- replace the Motor Module/Power Module
- replace Control Unit.
This message can be acknowledged without a POWER ON as follows:
- motion monitoring functions integrated in the drive: via Terminal Module 54F (TM54F) or PROFIsafe
- motion monitoring functions with SINUMERIK: via the machine control panel in acceptance test mode only

SI: Safety Integrated
201701 <location>SI Motion CU: 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 deceleration ramp).
As a result of this fault, after the time parameterized in p9556 has expired, or the speed threshold parameterized in
p9560 has been undershot, message C01700 "STOP A initiated" is output.
Possible causes:
- stop request from the second monitoring channel
- subsequent response to the message C01714 "SI Motion: Safely reduced speed exceeded".
- subsequent response to the message C01711 "SI Motion: Defect in a monitoring channel".
Remedy: - remove the cause of the fault on the second monitoring channel
- carry out a diagnostics routine for message C01714.
- carry out a diagnostics routine for message C01711.
This message can be acknowledged without a POWER ON as follows:
- motion monitoring functions integrated in the drive: via Terminal Module 54F (TM54F) or PROFIsafe
- motion monitoring functions with SINUMERIK: via the machine control panel in acceptance test mode only
Note:
SI: Safety Integrated
201706 <location>SI Motion CU: SBR limit undershot
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 C01700 "SI Motion: 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 be acknowledged without a POWER ON as follows:
- motion monitoring functions integrated in the drive: via Terminal Module 54F (TM54F) or PROFIsafe
- motion monitoring functions with SINUMERIK: via the machine control panel in acceptance test mode only
