ST500 | Factory Settings – How do I reset the inverter?

To reset the frequency inverter ST500 to factory settings, the parameter must be y0.00 = 1 or y0.00 =3 . In y0.00 =1 all parameters are set back to the factory settings but without engine data, at y0.00 =3 all parameters, including motor data are reset.

During the initial installation, we recommend to always use y0.00 = 3 to ensure that all parameters are at factory settings.
