What it means
C01707 is a Safety Integrated (SI) message with the manual title SI Motion P1 (CU): Tolerance for safe operating stop exceeded
. It comes from the SI Motion monitoring in the Control Unit (CU) and signals that, during a safe operating stop — the function the manuals abbreviate as SOS (Safe Operating Stop) or SBH (Safe operating stop) — the actual position has moved further away from the target position than the standstill tolerance allows. The shutdown of the drive that follows is reported by message C01701 "SI Motion: STOP B initiated".
Why it appears
- During the safe operating stop, the actual position has moved further away from the target position than the standstill tolerance permits.
- The drive is shut down as a result, and this shutdown is reported by message C01701 "SI Motion: STOP B initiated".
What to check
- Check whether safety faults are present and, if required, carry out the appropriate diagnostic routines for the particular faults.
- Check whether the standstill tolerance (p9530) matches the accuracy and the control dynamic performance of the axis.
Parameters the manual names
- p9530 — SI Motion standstill tolerance (Control Unit): this is the standstill tolerance monitored by C01707; use it to check whether the tolerance matches the accuracy and control dynamic performance of the axis.
Acknowledging and restarting
The manual's remedy is to carry out a POWER ON to acknowledge the message and restart the drive. The message can also be acknowledged without a POWER ON (safe acknowledgment) via:
- Terminal Module 54F (TM54F)
- onboard F-DI (only CU310-2)
- PROFIsafe
- machine control panel
The same on every family
Every manual that describes C01707 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS S120, S150 List Manual · p. 2676 |
| G130, G150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1464 |

Questions technicians ask
What does message C01707 in SINAMICS mean?
The SI Motion monitoring in the Control Unit has detected that, during the safe operating stop, the actual position moved further away from the target position than the standstill tolerance allows. The drive is then shut down by message C01701 "SI Motion: STOP B initiated".
How do I acknowledge and clear C01707?
The normal way is to carry out a POWER ON. Safe acknowledgment without a POWER ON is also possible, via Terminal Module 54F (TM54F), onboard F-DI (only CU310-2), PROFIsafe or the machine control panel.
Which parameter sets the standstill tolerance for C01707?
p9530, the SI Motion standstill tolerance in the Control Unit. Check that this tolerance matches the accuracy and the control dynamic performance of the axis.
Why does C01701 appear together with C01707?
C01707 reports that the standstill tolerance was exceeded during the safe operating stop; the shutdown of the drive that this triggers is reported as C01701 "SI Motion: STOP B initiated".
