OK...I think I know where this will end up but I thought I'd ask anyway.
Getting ready to connect up a VFD to my 'new' Whacheon lathe that uses a 7.5HP 3 phase motor. I like the idea of the VFD allowing me to run a 'large' motor on single phase 240V power, and the way it will ramp up the motor without full inrush. But, I don't like the way I will need to use the VFD controls to do the controlling....I'd rather use the switch that comes with the lathe.
So....theoretically...what would happen if the VFD were turned 'on' with no load - then the motor switch was flipped 'on' which placed the motor load on the VFD? I think it wouldn't like it...but I'm wondering if anyone has tried it?
