What it means
C30707 is a safety message from the Safety Integrated Motion monitoring (SI Motion P2). The Safe Operating Stop (SOS) watches a standstill axis: the drive compares the actual position of the axis with the target position. When the actual position has distanced itself further from the target position than the standstill tolerance allows, this message is raised. The shutdown of the drive is not carried out by C30707 itself — the drive is shut down by the accompanying message C30701 "SI Motion MM: STOP B initiated". In the manual's abbreviations, SI means Safety Integrated, SOS means Safe Operating Stop and SBH means safe operating stop.
Why it appears
- The actual position of the axis has distanced itself further from the target position than the standstill tolerance.
- The drive is shut down by the message C30701 "SI Motion MM: STOP B initiated", which accompanies this tolerance violation.
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 matches the accuracy and control dynamic performance of the axis (p9530).
Parameters the manual names
- p9530 — SI Motion standstill tolerance (Control Unit): the standstill tolerance against which the SOS monitoring judges the axis position; for this message, check whether it matches the accuracy and control dynamic performance of the axis.
Acknowledging and restarting
The message must be acknowledged before the drive will run again; a POWER ON does this. This message can be acknowledged without a POWER ON as follows (safe acknowledgment)
— via the Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe, or the machine control panel.
The same on every family
Every manual that describes C30707 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. 3000 |
| G130, G150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1694 |

Questions technicians ask
What does C30707 mean on a SINAMICS drive?
The SI Motion P2 Safe Operating Stop monitoring has detected that the axis actual position moved further from the target position than the standstill tolerance allows. The drive is shut down by the accompanying message C30701 "SI Motion MM: STOP B initiated".
How is C30707 acknowledged without switching the power off?
Through a safe acknowledgment: the Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe, or the machine control panel. Otherwise the message is acknowledged by a POWER ON.
Which parameter belongs to C30707?
p9530, the SI Motion standstill tolerance (Control Unit). Check whether this tolerance matches the accuracy and control dynamic performance of the axis.
What should I check first when C30707 appears?
Check whether other safety faults are present and, if required, carry out the diagnostic routines appropriate to those particular faults. Then verify that the standstill tolerance of the axis suits its accuracy and control dynamic performance.
