What it means
The drive reports SI Motion P2: STOP E initiated: a STOP E (retraction motion) has been started, so the drive is stopped, and once the parameterized transition time has expired, "Safe Operating Stop" (SOS) is activated. This Safety Integrated (SI) condition is described identically for the S120/S150 and the G130/G150. No message value is output with the message.
Why it appears
- A stop request was issued from the higher-level control.
- The message appears as a subsequent response to C30714 'SI Motion MM: Safely-Limited Speed exceeded'.
- The message appears as a subsequent response to C01715 'SI Motion CU: Safely-Limited Position exceeded'.
- The message appears as a 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 the messages C30714, C30715 and C30716.
Parameters the manual names
- p9354 — sets the SI Motion transition time from STOP E to SOS on the MM; this is the parameterized time after which SOS is activated once STOP E has been initiated.
- p9554 — sets the same SI Motion transition time from STOP E to SOS for the SBH on the CU.
Acknowledging and restarting
The manual explicitly describes how this message can be acknowledged without a POWER ON (safe acknowledgment): via the Terminal Module 54F (TM54F), via the onboard F-DI (only CU310-2), via PROFIsafe, or from the machine control panel. Remove the cause of the fault at the control before the drive is returned to operation.
The same on every family
Every manual that describes C30710 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. 3001 |
| 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 C30710 mean on a SINAMICS drive?
The Safety Integrated function STOP E (retraction motion) has been initiated: the drive is stopped and Safe Operating Stop (SOS) is activated after the parameterized transition time has expired.
Why was STOP E initiated?
Either the higher-level control issued a stop request, or C30710 appears as a subsequent response to C30714, C01715 or C30716.
How can C30710 be acknowledged without a POWER ON?
The manual lists safe acknowledgment via the Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe or the machine control panel.
Which parameter sets the time from STOP E to SOS?
p9354 sets the transition time on the MM and p9554 the corresponding time for the SBH on the CU; SOS becomes active once this parameterized time has expired.
