Question on e-stop wiring

I am wiring up my plasma controller and wasn't sure what connects up to relay OUT1 that says NoFaultOut in red. Is that part of the e-Stop circuit? or does it just turn on the LED for the output?
Thanks in advance

Usually the No fault out runs to the E stop or contactor that cuts power to other supply's in the cabinet
Here's an e-stop contactor schematic example

Is there a schematic for a plasma setup? I don’t have a VFD in my system. On my other table the e-stop switch only shut off the control board not any motors directly. The table would stop moving and shut off the torch. Is there a configuration in Acorn for dealing with the signal on the input for the estop?
taking a closer look at the schematic - it seems that I would need a 1 pole contactor to shut off the power to my steppers, probably put it after the circuit breaker to the steppers. Then the e-stop would shut off all of the steppers but still leave the control board powered up to hopefully shut off the torch
Does that sound correct?
I have a 10 amp circuit to my steppers - would I also need a 10a contactor? Do the contactors usually include a built in snubber? Be interested in part numbers and manufacturers if you have any recommendations

Yes in the Wizard you will Assign the E-Stop to the acorn input it is connected too. When the Acorn E-stop input is triggered the No fault output will be close if assigned.
For your application Ignore the VFD in the Schematic

The Contactor is totally up to you but it is recommended by Centroid for Safety. Powering off the control with the No fault out and E- stop is not recommended or necessary.
The Torch will be wired to the Output board as Normally open. So even if the Board and relay loose power the Output will Open since it needs power to close the relay.
