Defect in a monitoring channel

What does C30711 mean?

A defect has been detected in a monitoring channel, with fault value r2124 providing more detailed information. This condition often initiates a STOP response and an inverter fault, indicating a critical issue with the safety monitoring system that requires immediate attention.

• Temporary discrepancy between redundant monitoring channels (e.g., processor 1 and processor 2) within tolerance limits but indicating instability.
• Data cross-check error between internal safety processors, specifically indicated by r2124 values (0-2, 4-43, 58-999).
• Fluctuation in internal supply voltage to the safety logic components, causing transient errors.
• Electromagnetic interference (EMI) event causing a transient disturbance in safety data processing.
• Pre-warning of an impending hardware defect in the safety monitoring circuit, requiring attention.

Click steps to track your progress.

1. 1

   Record the exact additional information from r2124 (safety monitoring diagnostic code) for detailed analysis.

2. 2

   Check the inverter's ambient temperature and the internal component temperature (r0037) to ensure it's within operating limits (e.g., 0-50°C).

3. 3

   Verify grounding integrity of the inverter housing and control cabinet (PE connection resistance below 0.1 Ohm).

4. 4

   If r2124 indicates a transient data error (e.g., value 1), power cycle the inverter to clear internal registers.

5. 5

   Monitor the frequency of this alarm (r2122); if it recurs, prepare for deeper diagnostics or safety module replacement.
