Si Motion Mm: Sos/Sls Enable Missing; Si Motion Mm: Safely-Limited Speed Limit Value Too High; Si Motion Mm: Actual Value Synchronization Not Permissible - Siemens Sinamics S120 Diagnostic Manual

Remedy: - de-select the monitoring function involved (p9301, p9301, p9303, p9601, p9801).
- Upgrade the Motor Module firmware.

230683 <location>SI Motion MM: SOS/SLS enable missing
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The safety-relevant basic function "SOS/SLS" is not enabled in p9301 although other safety-relevant monitoring func-
tions are enabled.
Note:
This message does not result in a safety stop response.
Remedy: Enable the function "SOS/SLS" (p9301.0).
Note:
SI: Safety Integrated
SLS: Safely-Limited Speed / SG: Safely reduced speed
SOS: Safe Operating Stop / SBH: Safe operating stop

230685 <location>SI Motion MM: Safely-Limited Speed limit value too high
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The limit value for the function "Safely-Limited Speed" (SLS) is greater than the speed that corresponds to an encoder
limit frequency of 500 kHz.
Note:
This message does not result in a safety stop response.
Fault value (r0949, interpret decimal):
Maximum permissible speed.
Remedy: Correct the limit values for SLS and carry out a POWER ON.
Note:
SI: Safety Integrated
SLS: Safely-Limited Speed / SG: Safely reduced speed

230688 <location>SI Motion MM: Actual value synchronization not permissible
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: - It is not permissible to enable actual value synchronization for a 1-encoder system.
- It is not permissible to simultaneously enable actual value synchronization and a monitoring function with absolute
reference (SCA/SLP).
Note:
This fault results in a STOP A that cannot be acknowledged.
