What it means
F30672 signals that the software installed on the existing Control Unit does not support the safe drive-based motion monitoring function. SI stands for Safety Integrated. The manuals describe this fault identically for every family that lists it, so the same cause and the same remedy apply regardless of which of these converters shows the code.
Why it appears
- The software installed on the Control Unit does not support the safe drive-based motion monitoring function.
What to check
- Check whether faults are present in the safety function alignment between the two monitoring channels; these faults are signalled as F01655 and F30655. If faults are present, carry out the diagnostics for the faults involved.
- Use a Control Unit that supports the safe motion monitoring function.
- Upgrade the Control Unit software so that it supports the function.
Reading the message value
- The manual prints the message value only as the placeholder %1.
- For this fault the fault value can be read in r0949 and is to be interpreted as a decimal number.
- No decoding of the value is published: the manuals state that it is meant only for internal Siemens troubleshooting.
Parameters the manual names
- r0949 — holds the fault value belonging to F30672, to be read as a decimal number; the manual publishes no decoding because the value serves only internal Siemens troubleshooting.
Acknowledging and restarting
The fault itself triggers a STOP A that cannot be acknowledged, so the incompatibility has to be removed first (see the checks above). For the fault message, the manuals specify immediate acknowledgement via POWER ON, i.e. the drive power must be switched off and on again. While the fault is active the drive coasts down (OFF2) and will not start again until it has been acknowledged.
The same on every family
Every manual that describes F30672 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 | IMMEDIATELY (POWER ON) | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2987 |
| G130, G150 | OFF2 | IMMEDIATELY (POWER ON) | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1686 |

Questions technicians ask
What does fault F30672 mean on a SINAMICS drive?
It is raised when the software installed on the Control Unit does not support the safe drive-based motion monitoring function; SI stands for Safety Integrated.
How is F30672 cleared?
The fault causes a STOP A that cannot be acknowledged, so first remove the incompatibility itself — use a Control Unit that supports the safe motion monitoring function or upgrade the Control Unit software. The fault message is then acknowledged immediately via POWER ON.
Which other faults should I check together with F30672?
Check whether F01655 or F30655 are present, as these report faults in the safety function alignment between the two monitoring channels, and run the diagnostics for those faults if required.
What does r0949 show for F30672?
It holds the fault value of the message, interpreted as a decimal number. The manuals publish no decoding, since the value is intended only for internal Siemens troubleshooting.
