Pm 935 Tv Ordered

[tmarks11]

I hope you mean single phase VFD with a 3 phase motor, unless this is a vari-speed type of mechanical system.

PM-935TV has the typical bridgeport-style mechanical vari-speed head, thus no need for a VFD.

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.

The TV uses a mechanical/belt system for the variable speed like a BP IIRC.
