Params Defaulted

Allen-Bradley · PowerFlex 4M Adjustable Frequency AC Drive

What does F48 mean?

This fault indicates that the drive has been commanded to restore its parameters to factory default values, typically through a user action or system command. While not a malfunction, it means previous custom configurations are lost, which could lead to incorrect operation if not re-programmed.
