    A softstart could be a lower cost option over a VFD. We used softstarts on all pumps 10 hp and up to keep the pressure surges from damaging the membrane systems we built. I personally have done installations up to 150 hp. They are very compact, only a little bigger than a contactor. Once motor is at full speed a mechanical contactor jumps out the semiconductor switch. The mechanical contactor see no arcing or starting currents so it can be very tiny, and there is no power loss.

    The OP is talking about a CNC lathe with a VFD--not a manual lathe.

    I installed a soft start on my 15 hp manual turret lathe so the inrush wouldn't kick out my CNC lathe if I was using them at the same time.
