Defect in a monitoring channel

Was bedeutet F30611 ?

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.

• Internal hardware defect within the safety-related drive option module or integrated safety board.
• Discrepancy between redundant monitoring channels (e.g., processor 1 and processor 2) exceeding internal tolerance.
• Corrupted EEPROM data in the safety module preventing proper initialization or operation.
• Electromagnetic interference (EMI) affecting internal communication paths within the safety circuit.
• Permanent internal power supply failure to the safety logic components.

1. 1

   Record the exact fault value from r0949 (fault code additional info) for detailed diagnosis.

2. 2

   Power cycle the inverter and observe if the fault persists after re-initialization.

3. 3

   Perform a safety function hardware test by triggering STO and monitoring diagnostic bits r0947.x for correct response.

4. 4

   Verify module temperature (r0037) to rule out overheating of internal safety components.

5. 5

   If r0949 indicates an internal hardware error (e.g., value 10), prepare for safety module replacement.
