Siemens alarm F30600: SI MM: STOP A initiated
SINAMICS S120 drive fault · SINAMICS S120
What it means
The Safety Integrated function integrated in the Motor Module detected a fault and executed STOP A - pulse suppression via the module's own safety shutdown path. Typical triggers are an unsuccessful forced check of the safety shutdown path or the follow-up reaction to F30611 (defect in a monitoring channel). The decimal fault value identifies the source, including stop requests from the Control Unit and pulses-enabled/pulses-suppressed inconsistencies against STO state.
Likely causes
- forced checking procedure of the safety shutdown path failed
- follow-up response to fault F30611
- internal defect in the Motor Module safety circuitry
Triage note: Remedy per manual: select STO and de-select again; replace Motor Module if persistent.
