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 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

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.
i used this one. seems to be the most common from what i've researched

Good, that is the one I picked on to replace the RS232 version I was using.
Thanks.

I added this switch panel I made, and I blew out three of the switches before I realized I was wiring them wrong.. I know stupid me. I’m worried I fried something somewhere. But everything seems to work fine. I’m cutting now As we speak. I just can’t get the rs485 to Communicate with the vfd.
I can't see as the photos are not very defined, you may have wired the sub box incorrect as well I don't see a separate Ground Bus as the Neutral has to be on it's own Isolated Bus, for any sub panels
Mounting component's on wood is a bad Idea you need a metal plate, Aluminum or steel unpainted where parts are mounted, this plate becomes the Ground Plane and is Ground bonded to the Main supply Ground

I’m not Much of an electrician, but my neutral is directly connected to the ground bus bar, wouldn’t that make them okay to ground to the panel?
That computer has been there for a long time. It’s just a bunch of scrap from an old drawer I threw together. I plan on making a better one later but this is low on my priority list.
My neutral is connected to the ground bus bar via a screw, I also ground the bus bar to the panel. , then I took a wire and connected my switch panel frame to the ground bus bar on my sub frame.
Ran my hits from the breakers and used the switch panel as the neutral/ground.
You think this wiring could be causing interference with the rs485 adapter or the vfd?
Oh, I see. That’s an easy fix. My sub panel came with the bus bar attached to the neutral connection, my mistake was assuming it was the same wiring as the main. So I’ll get a few bus bars, and run an isolated neutral, and ground inside both my switch panel and my sub panel.
Could this cause communication issues with the vfd?
You only need the panel to be wired correct any other wiring outside of the sub panel would be normal wiring practice's
Check that the Built in bus to see if it is isolated or not most sub box's are when you buy them and some you just need to add the Ground Bus which mounts direct to the metal Box
A power Filter will help with any EMI noise this should be mounted close to the input power to the VFD Drive and all mounted on a Grounded metal Plate
Lambada RSEN-2030L for your filter
