This error occurs when an active ignore bit is detected outside of an EnDat forced dynamic sampling operation. This indicates an invalid state in the EnDat communication protocol or an unexpected condition related to encoder sampling, potentially affecting safety functions.
Click steps to track your progress.
Restart the control system completely (power cycle the controller).
If the error recurs, check the current software version of the controller and update it if a newer, more stable version is available.
Inspect the EnDat encoder and its wiring for any intermittent faults or communication issues that could lead to unexpected bit states.
Collect detailed diagnostic logs if available after a restart to pinpoint the exact timing and context of the ignore bit activation.
