    If the VFD can only be programed to 120Hz max then you will burn smoke your 400Hz spindle so don't run it to long or your cheap drive will be an expensive drive when you have to replace your spindle motor as well

    How does a low frequency burn a motor? The inverter I got with the spindle motor (as a set) can be set with a pot from 0 to 400hz. I also set the drive for a low current and voltage

    I guess you will find out the VFD Drive Parameters must be set to the 400Hz or the motor spec's for the spindle to survive
