Sd3 Interruption of the digital frequency coupling

What does x083 mean?

The input signal 'Lamp Control' at terminal X9/8 is LOW, indicating an interruption of the digital frequency coupling. If the response (C0587) is set to 'Warning' (2), continued operation without addressing this fault can potentially damage the drive.

• Broken or loose wire connection to terminal X9/8, causing the digital input signal to drop to LOW.
• External control device (e.g., PLC, safety relay) failing to provide the expected HIGH signal to terminal X9/8.
• Power supply issue to the external control device or sensor that drives the signal at terminal X9/8.
• Incorrect configuration of parameter C0587 (Digital Frequency Coupling Response) allowing operation under fault conditions.
• Internal hardware fault on the drive's input X9/8, preventing proper signal detection.

Click steps to track your progress.

1. 1

   Measure the voltage at terminal X9/8 relative to ground (0V) with a multimeter; expect a HIGH (e.g., 24VDC) signal when active.

2. 2

   Inspect the wiring connection at terminal X9/8 for continuity and secure fastening, checking for breaks or corrosion.

3. 3

   Verify the output status of the external control device (e.g., PLC output card) that supplies the signal to X9/8.

4. 4

   Check parameter C0587; if set to 'Warning' (2), change it to 'Fault' (1) for immediate shutdown upon signal loss for diagnostic purposes.

5. 5

   If the external signal is confirmed HIGH and wiring is intact, perform an input self-test if available, or consider an internal hardware fault.
