Si Motion Cu: Tolerance For Safe Operating Stop Exceeded; Si Motion Cu: Stop C Initiated - Siemens Sinamics S120 Diagnostic Manual

201707 <location>SI Motion CU: Tolerance for safe operating stop exceeded
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The actual position has distanced itself further from the target position than the standstill tolerance.
The drive is shut down by the message C01701 "SI Motion: STOP B initiated".
Remedy: - check whether safety faults are present and if required carry out the appropriate diagnostic routines for the particular
faults.
- check whether the standstill tolerance matches the accuracy and control dynamic performance of the axis.
- carry out a POWER ON.
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
SOS: Safe Operating Stop / SBH: Safe operating stop

201708 <location>SI Motion CU: STOP C initiated
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: STOP2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP C (braking along the OFF3 deceleration ramp).
"Safe Operating Stop" (SOS) is activated after the parameterized timer has expired.
Possible causes:
- stop request from the higher-level control.
- subsequent response to the message C01714 "SI Motion: Safely reduced speed exceeded".
- subsequent response to the message C01715 "SI Motion: Safe end stop exceeded".
See also: p9552 (SI Motion transition time STOP C to SOS (SBH) (Control Unit))
Remedy: - remove the cause of the fault at the control.
- carry out a diagnostics routine for message C01714.
This message can be acknowledged 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
