PM-935TV has the typical bridgeport-style mechanical vari-speed head, thus no need for a VFD.I hope you mean single phase VFD with a 3 phase motor, unless this is a vari-speed type of mechanical system.
The PM-935TS has the typical multi-belt reduction system; ordering with a three phase motor and adding a VFD increases the convenience in selecting the speed of your choice.
