Re: Turning Spindle Off and On

Ok, I am going to order the Solid State relay from Fred today, I
have a vfd drive running a 3 phase motor. Here is a link to a
schematic for the control. I am assuming I run a 5v pin and ground
pin from the break out board to the SSR. Then where do I hook the
other terminals on the SSR to the vfd? Here is the link
