What it means
C01714 is the safety message "SI Motion P1 (CU): Safely-Limited Speed exceeded". The SI Motion P1 monitoring in the Control Unit (CU) raises it when the drive has moved faster than the velocity limit value configured in p9531, i.e. the active Safely-Limited Speed stage (SLS, also referred to as SG — safely reduced speed) has been exceeded. The drive is then stopped with the stop response configured in p9563.
Why it appears
- The drive has moved faster than the velocity limit value set in p9531; the message value shows which stage (SLS1 to SLS4) was exceeded.
- On G130, G150, S120 and S150 the message value can also report that the encoder limit frequency was exceeded (value 1000).
What to check
- Check the traversing/motion program in the control.
- Check the limits for SLS and, if required, adapt p9531 accordingly.
Reading the message value
The drive writes the message value for this code either into r9749 (interpret decimal — G130, G150, S120 and S150) or into r2124 (interpret decimal — G120). The decimal value identifies what was exceeded:
- 100: SLS1 exceeded
- 200: SLS2 exceeded
- 300: SLS3 exceeded
- 400: SLS4 exceeded
- 1000: Encoder limit frequency exceeded — printed for G130, G150, S120 and S150; for the G120 the manual lists only the values 100 to 400
Parameters the manual names
- p9531 — SI Motion SLS (SG) limit values (Control Unit): the SLS velocity limits; check them for this message and adapt if required.
- p9563 — SI Motion SLS (SG)-specific stop response (Control Unit): the stop response the drive executes when the SLS limit is exceeded.
- r9749 — SI message value: read here, interpreted as a decimal number, to see which SLS stage or limit was exceeded (G130, G150, S120, S150).
- r2124 — Alarm value: on the G120 the message value is read here, interpreted as a decimal number.
Acknowledging and restarting
Once the cause has been removed, the message is acknowledged before the drive restarts. The manuals describe a safe acknowledgment that avoids a POWER ON: This message can be acknowledged without a POWER ON as follows (safe acknowledgment)
— via the Terminal Module 54F (TM54F), via the onboard F-DI (only CU310-2), via PROFIsafe, or via the machine control panel. On the G120 the message is acknowledged using "Acknowledge internal event".
What differs between the drive families
Straight from the manuals' own fields — C01714 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1474 |
| S120, S150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS S120, S150 List Manual · p. 2694 |
| G120 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | — | SINAMICS G120 · p. 857 |

Questions technicians ask
What does SINAMICS fault C01714 mean?
The SI Motion P1 safety monitoring in the Control Unit has detected that the drive moved faster than the Safely-Limited Speed velocity limit value in p9531. The drive is stopped as a result of the stop response configured in p9563.
How do I acknowledge C01714 without a POWER ON?
On G130, G150, S120 and S150 the message can be acknowledged safely without a POWER ON via the Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe or the machine control panel. On the G120 it is acknowledged using "Acknowledge internal event".
Where do I read the message value for C01714?
In r9749 (interpret decimal) on G130, G150, S120 and S150, and in r2124 on the G120. Values 100 to 400 identify the exceeded stage SLS1 to SLS4; value 1000 means the encoder limit frequency was exceeded (not listed for the G120).
Which parameters belong to fault C01714?
p9531 holds the SLS limit values and p9563 the SLS-specific stop response of the Control Unit. Check the limits in p9531 and adapt them if required.
