A defect has been detected in a monitoring channel. The fault value r0949 provides more detailed information on the specific issue. This indicates a critical problem with safety monitoring that needs further investigation to ensure safe operation.
Click steps to track your progress.
Record the exact fault value from r0949 (fault code additional info) for detailed diagnosis.
Power cycle the inverter and observe if the fault persists after re-initialization.
Perform a safety function hardware test by triggering STO and monitoring diagnostic bits r0947.x for correct response.
Verify module temperature (r0037) to rule out overheating of internal safety components.
If r0949 indicates an internal hardware error (e.g., value 10), prepare for safety module replacement.
