For the people that don't know Nez, he is a perfectionist and does very nice clean work.All of his projects are well thought out.
Not sure why you need the logic board and relays as the VFD has all the logic control within itself to run all the controls in a lathe. E-Stop, forward / Stop / reverse, jog, speed (RPM), coolant pump.
The units that have a potentiometer will allow you variable speed with a twist of a knob. You can add braking resistors for instant stoping.
