8. How to use Variable Frequency Drive (VFD) for Manual Lathe?
VFDs can actually make MORE low RPM torque if they're vector type. Those are becomming more common, but the really cheap ones are still straight v/hz which provides a constant torque over most of the RPM band. You can get away with a cheap v/hz type VFD on that lathe because of the range of speeds it has. You really don't need to boost the low RPM torque, but it COULD be nice. If it were me, I'd get a vector type drive.
Third, NO, you can wire the fwd/neutral/reverse switch to the VFD to do the same functions. In fact, where the power and e-stop are is where I'd put your speed control knob. Looks like there's a couple spots for controls blocked off. So, you wouldn't need a control box! You can also wire the e-stop to the VFD, which is the way I'd do it.
Fourth, the foot brake needs to be wired to the VFD the same way you would the e-stop. You'll also need to set the VFD to free run stop so it doesn't try to fight the foot brake, but that's easy.
Fifth, the control box isn't necessary, as stated above, all the lathes controls can be wired to the VFD to make it do what the controls originally did.
Sixth, see above! All you need for a speed control is a potentiometer. Put the pot where the unused holes are by the e-stop.
