What it means
C30715 is a safety message of SI Motion: the axis has moved past a parameterized position that is monitored by the "SLP" function (Safely-Limited Position). The G130, G150, S120 and S150 manuals describe this message with the same cause and the same remedy, so everything below applies to each of them. Which of the two monitored limits was passed — SLP1 or SLP2 — is read from the message value in r9749.
Why it appears
- The axis has moved past a parameterized position that the "SLP" (Safely-Limited Position) function monitors.
- Either of the two monitored limits can be the one that was passed: SLP1 or SLP2 — the message value shows which.
What to check
- Read the message value in r9749 and interpret it as a decimal number: 10 = SLP1 violated, 20 = SLP2 violated.
- Check the traversing/motion program in the control.
- Check the limits for the "SLP" function and, if required, adapt them (p9534, p9535).
Reading the message value
- The manual prints the message value as a placeholder (%1); the drive writes it into r9749 (SI message value). Interpret the value as a decimal number.
- 10: SLP1 violated.
- 20: SLP2 violated.
Parameters the manual names
- r9749 (SI message value / SI msg_value): read here, interpreted as a decimal number, to see whether SLP1 or SLP2 was violated.
- p9534 (SI Motion SLP (SE) upper limit values (Control Unit)): check the upper SLP limit here and adapt it if required.
- p9535 (SI Motion SLP (SE) lower limit values (Control Unit)): check the lower SLP limit here and adapt it if required.
- p9334 (SI Motion SLP upper limit values (Motor Module)): the note to this message cross-refers to these upper SLP limit values of the Motor Module.
- p9335 (SI Motion SLP lower limit values (Motor Module)): the note to this message cross-refers to these lower SLP limit values of the Motor Module.
Acknowledging and restarting
The message is normally acknowledged with POWER ON. The manual also describes a safe acknowledgment without POWER ON. Prerequisite: deselect "SLP" function and retract the axis into the permitted position range
. The safe acknowledgment is then carried out using one of the following options:
- Terminal Module 54F (TM54F)
- onboard F-DI (only CU310-2)
- PROFIsafe
- machine control panel
The same on every family
Every manual that describes C30715 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1699 |
| S120, S150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS S120, S150 List Manual · p. 3008 |

Questions technicians ask
What does SINAMICS fault C30715 mean?
It is an SI Motion safety message telling you that the axis has moved past a parameterized position monitored by the Safely-Limited Position (SLP) function. The message value in r9749, read as a decimal number, shows whether SLP1 (10) or SLP2 (20) was violated.
How can I clear C30715 without switching the power off and on?
Deselect the "SLP" function and retract the axis into the permitted position range, then carry out a safe acknowledgment via the Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe or the machine control panel.
Which parameters hold the SLP limits for C30715?
p9534 and p9535 contain the upper and lower SLP limit values in the Control Unit; check them and adapt them if required. The manual also cross-refers to the corresponding Motor Module limit values p9334 and p9335.
