To reset the Inovance MD520 Series inverter to factory default settings, set parameter FP-01 to one of the following values:

- Set FP-01 = 0: No action.
- Set FP-01 = 1: Restore parameters (excluding motor parameters and frequency reference) to factory settings.
- Set FP-01 = 503: Restore all parameters (including motor parameters) to factory settings, except FP-00, FP-01, and parameters in group FF.

This will reset the inverter according to the selected option.
