Paul your not listening properly because if you'd done as I suggested then the spindle wouldn't start at all. And the speed would be controlled from the VFD using what ever speed you set.

You need to take a few steps back and deal with one problem at a time. Stop changing settings willy nilly because this makes the Job of helping so much harder. All this does is waste yours and my time by chasing false issues. I need you to only change one thing at a time then report what happens.

First all you need to do is get Relay #1 working. Forget #2 & #3 we don't need them so you can turn them off on the BOB and disable them in Mach3.

Straight away I see that you have the Wrong Pin number set for Relay #1. It should be Pin 16 not 14.
Pin 14 is for the PWM Speed control which I believe is working fine just needs setting up for correct speeds which can be done later. NOT NOW.!!

So to re cap Tell me which terminals your connecting to on the Relay.
Set Output #1 = pin16 Active LO.
Turn off the Enable for Outputs #2, #3.


Next the relay will have 3 terminals which are you connecting to.?
