I'm changing my SB lathe from an expired 1/2hp single phase to a new Emerson 1/2hp 3 phase and a VFD. After wiring everything and testing I found I was only getting 630 rpm from the motor and I can stop the pulley with my bare hand. Set all the parameters needed and no change in the rpm. I thought maybe I wired in accidentally the motor for high voltage. But after checking the label I confirmed I wired it for low. Thats when I first noticed the label shows the high and low to be wired the same. Can this be correct or am I missing something?
