What it means
The manuals print this safety message as “SI Motion P2: STOP D initiated”. It is raised by the Safety Integrated (SI) motion monitoring when the drive is stopped via a STOP D — braking along the path. “Safe Operating Stop” (SOS) is activated after the parameterized time has expired; the transition time from STOP D to SOS is set in p9353 (Motor Module) or in p9553 (SBH, Control Unit). The STOP D itself is either a stop request from the Control Unit or the subsequent response to one of the safety messages named under causes.
Why it appears
- A stop request from the Control Unit.
- The message is the subsequent response to C30714 “SI Motion MM: Safely-Limited Speed exceeded”.
- The message is the subsequent response to C01715 “SI Motion CU: Safely-Limited Position exceeded”.
- The message is the subsequent response to C30716 “SI Motion MM: tolerance for safe motion direction exceeded”.
What to check
- Remove the cause of the fault at the control.
- Carry out a diagnostics routine for messages C30714, C30715 and C30716.
- Acknowledge the message via one of the safe acknowledgment paths listed under reset below.
Parameters the manual names
- p9353 — SI Motion transition time STOP D to SOS (Motor Module): holds the parameterized time after whose expiry SOS is activated once the STOP D has been initiated, for the Motor Module.
- p9553 — SI Motion transition time STOP D to SOS (SBH) (Control Unit): holds the corresponding parameterized STOP D to SOS transition time for the SBH in the Control Unit.
Acknowledging and restarting
The manual describes a safe acknowledgment for this message: it can be acknowledged without a POWER ON via a Terminal Module 54F (TM54F), via the onboard F-DI (only CU310-2), via PROFIsafe, or via the machine control panel. Before acknowledging, remove the cause of the fault at the control and carry out the diagnostics routine for messages C30714, C30715 and C30716.
What differs between the drive families
Straight from the manuals' own fields — C30709 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | — | — | 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. 1695 |

Questions technicians ask
What does C30709 SI Motion P2: STOP D initiated mean?
The Safety Integrated motion monitoring has stopped the drive via a STOP D, i.e. braking along the path. After the parameterized transition time has expired, Safe Operating Stop (SOS) is activated.
Why does C30709 appear?
Either a stop request came from the Control Unit, or the message is the subsequent response to C30714, C01715 or C30716.
How do I acknowledge C30709 without a POWER ON?
Via safe acknowledgment: a Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe, or the machine control panel. Remove the cause at the control and run the diagnostics routine for C30714, C30715 and C30716 first.
Which parameters set the STOP D to SOS time for C30709?
p9353 sets the transition time for the Motor Module, and p9553 sets the corresponding time for the SBH in the Control Unit.
