A. A variable frequency drive (VFD) refers to AC drives only and a variable speed drive (VSD) refers to either AC Drives or DC Drives. VFDâs vary the speed of an AC motor by varying the frequency to the motor. VSDâs referring to DC motors vary the speed by varying the voltage to the motor.. Yes, a variable frequency drive can replace a soft start starter, since most drives give you a current limiting ramp to start and stop your motor. BUT, if you do not need to vary the production speed of your motor, then the soft start starter is still the correct product for the application.
