Chris.....from the drive manual_"PD008 Max. Voltage Set Range:0.1—* Unit:0.1V Factory Setting:220/380VThis parameter should be set according to the rated value of the motor’s nameplate. The factorysetting is 380V for 380V class motor and 220V for 220V class motor. The setting range of thisparameter is restricted by the voltage rating of the inverter. In case of the motor relatively far awayfrom the inverter this set value can be increased properly."
