I'm seriously considering one of these.
VFD
I'd like to be able to power my 5hp lathe and my 3hp mill with their original 3ph motors. I converted them to 3hp & 1hp motors years ago but kept the motors in "inventory".
I have no intention of running the 2 machines simultaneously, god knows, I have enough trouble running one machine at a time.
I'm just wondering if there's a way to safely perform the changeover from one machine to the other.
I've read that there can be no switches between the VFD and the motor(s) it's powering while the VFD is powered up.
I'd also like to know if the VFD would need to be reprogrammed/adjusted going from 3 to 5 hp. and vice versa.
Anybody have any thoughts?
