C01714 SI Motion P1 (CU): Safely Limited Speed exceeded
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive has moved faster than that specified by the velocity limit value (p9531). The drive is stopped as a result of
the configured stop response (p9563).
Message value (r2124, interpret decimal):
100: SLS1 exceeded.
200: SLS2 exceeded.
300: SLS3 exceeded.
400: SLS4 exceeded.
Remedy: - check the traversing/motion program in the control.
- check limits for SLS and if required adapt accordingly (p9531).
This message can be acknowledged using "Acknowledge internal event".
Note:
SLS: Safely Limited Speed

1))
C01716 SI Motion P1 (CU): Tolerance for safe motion direction exceeded
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The tolerance for the "safe motion direction" function was exceeded. The drive is stopped as a result of the
configured stop response (p9566).
Message value (r2124, interpret decimal):
0: Tolerance for the "safe motion direction positive" function exceeded.
1: Tolerance for the "safe motion direction negative" function exceeded.
Remedy: - check the traversing/motion program in the control.
- check the tolerance for "SDI" function and if required, adapt (p9564).
This message can be acknowledged as follows:
- Deselect the "SDI" function and select again.
- carry out safe acknowledgment via "Acknowledgment internal event".
Note:
SDI: Safe Direction (safe motion direction)
SI: Safety Integrated

Motion SDI stop response (processor 1))
C01770 SI Motion P1 (CU): Discrepancy error of the fail-safe inputs
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The fail-safe digital inputs (F-DI) show a different state longer than that parameterized in p10002 / p10102.
Fault value (r0949, interpret binary):
Bit 0: Discrepancy error for F-DI 0
Bit 1: Discrepancy error for F-DI 1
...
Note:
If several discrepancy errors occur consecutively, then this message is only signaled for the first error that occurs.
