Defect when processing F-IO

What does C30712 mean?

A defect has occurred during the processing of fail-safe inputs/outputs (F-IO), potentially due to incorrect wiring or parameter settings. This can compromise the integrity of safety-related I/O signals, leading to unpredictable safety reactions or system failures.

• Incorrect wiring of fail-safe digital inputs/outputs (F-DI/F-DO) to external devices (e.g., short to ground, short to 24VDC, open circuit).
• External F-IO device (e.g., safety light curtain, safety gate switch) malfunction or faulty output signal.
• Discrepancy in dual-channel F-IO signals (e.g., both channels not switching simultaneously) exceeding the parameterized discrepancy time (P30700).
• Parameterization error for F-IO (e.g., P30701, P30702 for input/output type) not matching physical setup.
• Electromagnetic interference (EMI) affecting the F-IO signal integrity, causing transient errors.

Click steps to track your progress.

1. 1

   Identify the specific F-IO channel (e.g., F-DI0/F-DI1) indicated by the diagnostic message (r2124).

2. 2

   Perform continuity checks on the wiring for the affected F-IO channel from the inverter terminal (e.g., X1:F-DI0) to the external device.

3. 3

   Measure the voltage levels at the F-IO terminals (e.g., X1:F-DI0, X1:F-DI1) to confirm signal integrity (e.g., 24VDC present).

4. 4

   Test the external safety device connected to the F-IO for correct operation (e.g., actuate a safety switch and observe its output voltage).

5. 5

   Verify the discrepancy time setting (P30700) for relevant F-DI pairs and adjust if necessary, ensuring it allows for natural switching delays.

6. 6

   Perform an F-IO cross-check test (e.g., via P30709) if available in the safety diagnostics, monitoring result r2125.
