Resetting a Fuji Electric variable frequency drive back to its original factory default settings requires navigating the digital keypad interface. To execute this on models like the Frenic series, enter the menu screen by pressing the Program button, navigate down to the data check parameter section, and locate function code H03. By holding down the stop button while pressing the upper navigation arrow, you can change the parameter value to initial settings. Storing this selection resets the drive parameters, after which you should cycle power to the unit by turning off the main disconnect until the display blanks out completely before powering it back on.
