Is this right?

Power supply connection.

Thanks,
For the A/C side, do I have that right?
Green is ground - bolt to chasis or power supply
Black to HoT
White to Neutral?

And the E-Stop has 4 terminals
One of the green pin 10
One of the red to -V

Thanks, don't want to be guessing here

Green/Ground connects to the FG terminal.

Black connects to pin1 AC/L (line)
White connects to pin2 AC/N (neutral)

E-STOP SWITCH: Connect a single pole, single throw (SPST) switch to the DISABLE input Pos 10 on the MAIN TERMINAL BLOCK. The other end of the switch goes to Pos 12 on the terminal block. Opening the switch disables the G540 and closing the switch enables it. While disabled, the motors freewheel (zero torque) and the OUTPUT
terminals shut off.

Ok I think I got it now.
On the Gecko G540 manual, in the suggested wiring diagram, it specifies a Relay power supply with two dc relay coils. Do I need that? What is that for? They connect to pins 5 and 6.
Will pins 7,8, and 9 if connected to my X2 motor control actually control my spindle speed with mach 3? I think I asked this already but didn't get any clear answers.

The relay's are optional, they could be used to control a coolant pump or a simple enable/disable spindle motor etc...

You may be able to use the VFD output for your X2, the Gecko VFD connection would take the place of the potentiometer on the X2.

I am not sure which one of the wires on the pot is the output though.

The attached video is informative.

Well I got all the motors turning fine in mach3. I used the G540 presets. Has the steps at 20000 and they seem to turn pretty slow. Anyone know the ideal settings for the 387 motors with the cnc fusion ballscrew upgades. I'm referring here to steps, velocity, acceleration under the motor tuning page.
