The frequency converter's parameter settings have been reset to their factory default values, typically following a manual reset operation. This means all previous application-specific configurations are lost, and the drive will operate with generic settings.
Click steps to track your progress.
Confirm if a factory reset (e.g., P14-22 = 1 or 2) was intentionally performed or accidentally triggered.
Reload the last known good parameter set from a backup (e.g., using LCP copy/paste function or PC software tool).
Manually re-enter all necessary application-specific parameters, paying close attention to motor data (P1-20 to P1-25).
After re-entering parameters, perform an Automatic Motor Adaptation (AMA) to optimize motor control.
Check the control card's error log (if available) for any underlying internal faults that might have triggered the reset.
