F048

Params Defaulted

Allen-Bradley · PowerFlex 520-series Adjustable Frequency AC Drive

What does F048 mean?

The drive has received a command to write its factory default values to the EEPROM (non-volatile memory), overwriting any custom configuration settings. This fault often occurs after a parameter reset operation, meaning the drive will now operate with its base settings and requires reprogramming for specific applications.
