I'm looking to replace the existing drive in my Colchester Chipmaster lathe (Kopp variator + 3hp/2.2kw single-phase motor) with a VFD and 2 or 3hp (1.5 or 2.2kw) 3-phase motor, running over a 20Hz-120HZ frequency range (nominal line frequency is 60Hz). I've tried to educate myself by reading various posts and tutorials, but I've only managed to absorb the basic concepts, so when it comes to choosing the right vfd for the job, I'm not convinced I'v selected the right piece of hardware. I also want to be sure a remote potentiometer may be wired in, instead of using the one next to the keypad. I am aware of the motor losing torque at lower frequencies and the pitfalls of using a non-inverter rated motor, etc. etc. The unit I've picked out (please see specifications in the image below--hope it's readable) seems like the best bang for the buck, but if anyone can suggest a better unit for the application, I'm all ears. This unit is selling for about $225 USD + shipping.
EDIT: Input to the vfd will be single-phase, not 3-phase, so correct model no. is L510-203-H1-U; all other specs are the same.
