What it means
C01709 is a safety message from the SI Motion P1 monitoring in the Control Unit (CU). The drive is stopped via a STOP D (braking along the path).
When the parameterized time has expired, "Safe Operating Stop" (SOS) is activated; the transition time from STOP D to SOS (SBH) is set in p9553. The message therefore reports that this safety-related stop has been initiated — either on request from the higher-level control or as the follow-up to one of the SI Motion messages C01714, C01715 or C01716. Abbreviations per the manual: SI — Safety Integrated; SOS — Safe Operating Stop; SBH — Safe operating stop.
Why it appears
- A stop request has been issued by the higher-level control.
- The message is the subsequent response to C01714 "SI Motion CU: 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 C01716 "SI Motion CU: tolerance for safe motion direction exceeded".
What to check
- Remove the cause of the fault at the control — establish why the higher-level control issued the stop request.
- If C01714, C01715 or C01716 was raised beforehand, carry out a diagnostics routine for message C01714/C01715/C01716.
Parameters the manual names
- p9553 — SI Motion transition time STOP D to SOS (SBH) (Control Unit); for this code it is the parameterized time that must expire after STOP D has been initiated before Safe Operating Stop becomes active.
Acknowledging and restarting
The message is acknowledged immediately by powering the drive off and on again (POWER ON). The manual also describes safe acknowledgment without a POWER ON, using one of the following: Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe, or the machine control panel. Before restarting, remove the cause of the fault at the control and resolve any preceding C01714/C01715/C01716 message.
The same on every family
Every manual that describes C01709 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. 2677 |
| G130, G150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1465 |

Questions technicians ask
What does C01709 mean on a SINAMICS drive?
It reports that the SI Motion P1 safety monitoring in the Control Unit has stopped the drive via a STOP D — braking along the path. Safe Operating Stop (SOS) is activated once the parameterized transition time (p9553) has expired.
Why was STOP D initiated?
Either the higher-level control issued a stop request, or the message is the subsequent response to C01714 (Safely Limited Speed exceeded), C01715 (Safely Limited Position exceeded) or C01716 (tolerance for safe motion direction exceeded).
Can C01709 be acknowledged without a POWER ON?
Yes. The manual lists safe acknowledgment via Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe or the machine control panel; otherwise the message is acknowledged immediately with a POWER ON.
What is p9553 used for with C01709?
p9553 is the SI Motion transition time from STOP D to SOS (SBH) in the Control Unit — the parameterized time after which Safe Operating Stop becomes active once STOP D has been initiated.
