You got it working for now, but I can assure you that you are going to come back. So plan ahead. Maybe getting a simple UC100 and upgrading to UCCNC would be the simplest way out:...

That fault signal is common with the mains of the motor. You cannot hook it up directly to inputs on the masso as it will create a ground loop. Please check these boards that will help you wire...

Maybe this one will work for you:

I would think that the dual probe should work, but I really have never tried it. I checked the manual, but did not find anything that would shed light on the issue. I know that on other programs...

UCCNC or Mach4 are good options for your UC100. Mach3 has been unsupported for about 8 years now.

The probe is just a switch.

You could get this working with these servos:

Nice looking? What control software are you using?

The higher the resolution the smoother the motion is, but you tend to lose torque. So you need to play with them while the motors are working under load until you get the optimal performance. Maybe...

Maybe these recomendations may help:

This unit cannot process the input signals in real-time, so input signals may not be that useful anyway.

If you are on a tight budget, you can retrofit this keeping the original motors and just replace the servo drivers:

Ethernet may be a much better option. Consider the UC400ETH. It is more stable.

You need to configure UCCNC to control the spindle using PWM and use two outputs to control the FOR and REV signals. The info you are looking for is in the manual of the G540.

Arturo Duncan...

From what you are saying, I see that you have the jumpers set to operate the spindle on international mode. Check the jumpers and move them to US Mode. Note that on international mode relay1 is...

Here is how this works:
1. Your VFD is expecting FOR and REV signals, so make sure the jumpers on the C76 are set to US Mode.
2. Verify that when you call M3 Relay1 activates and when you call M4...

We have a connector board for those servos:

Use Mach4 or UCCNC.

Did you get this sorted out?

The first thing that comes to mind, is to run the Utilityxxx software to reestablish the connection. Maybe you just need to whitelist the device on the networks firewall.
