Signal supervision

What does A8B0 mean?

This warning is generated by a signal supervision function, indicating an abnormality or unexpected condition in a monitored signal, potentially due to out-of-range values, signal loss, or noise. This can affect the drive's control accuracy or lead to unexpected behavior.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the integrity of the sensor, wiring, and input module associated with the supervised signal.

2. 4

   Adjust supervision thresholds if the signal's normal operating range has changed due to application requirements.
