    I haven’t this time around I forgot. But that’s only for the speed control correct? Either way my relay isn’t clicking. I do have a meter. So what should I check and for what voltage should I expect to see?

    Either you are not getting the control from signal from Mach or the output of the G540 may be shot.
    You should get ~1v or so from 48v GND (common) to the relay pin connected to the G540, and 48v from GND (common) to the other pin, if 48v on both, then the relay is not picked up.
    Do you have a diode to place across the coil?

    I got it to work with the rs485. I downloaded the haunyang vfd plugin from
    Mach 3’s website. Hooked up a couple wires and that was basically it.

    That's is the best way with these VFD Drives you have much better control with the speeds control

    If it was not clicking then you either have something wired incorrect or a configuration problem with your output pins

    Yes it is a very nice way for control and eliminates the necessity to convert the Mach digital signal to analogue.
    Which was the convertor interface you used?
    Did you use the plug-in from Sebastien?

    I tried that one first. But Mach 3 said that the plugin was defective and to remove it. Upon some short research I found the other plugin from
    The machsupport page

    https://www.machsupport.com/forum/index.php?topic=14182.0

    A big part of me wants to tear it back
    Apart to find out what I was doing wrong. But it’s working great now and I really don’t want to push my luck.
