I have a working E-stop now. Still no power to the coil of CNT1 however.
MPG1 encoder error and Spindle fault. I expect the SF since I have not got the VFD fully wired yet.

Still not getting power to the E-Stop for some reason.
It is pretty hard to provide guidance here without seeing your as-built wiring diagram.

Let us suppose, in the absence of any real information, that you have:
1) A transformer with a 24VAC secondary (call these wires 24VAC L1 and L2)
2) A fuse in one leg of that 24VAC output supply (say, in the 24VAC L1 leg)
3) An emergency stop coil circuit that includes only OUT1 and the Emergency Stop pushbutton, as follows:
a) From the 24VAC L1 fuse to OUT1 COM
b) From OUT1 to one side of one of the E-stop button NC contacts
c) From the other side of that NC contact to the contactor A1 terminal
d) From the contactor A2 terminal back to the 24VAC L2.
This makes perfect sense to me the way you wrote this out. Why doesn't the diagram I was given with the kit have the woring this way? Maybe it does and I am not seeing it....

Will introduce the 24VAC into the E-stop wiring as you suggest.

Thanks!

One more question while I am looking at the E-stop...the one on the remote control panel is also not working. How does one connect the two E-stops together?

The print shows them both but not how they interact from what I can see.

additional estop switches are wired in series.

Supposing that you are using schematic S14746.R18:
1) A transformer with a 24VAC secondary --> see component "T1", location B4, wires 501 and 502
2) A fuse in one leg of that 24VAC output supply --> see fuse "F5", location D3, wire 501 in, wire 503 out
3) An emergency stop coil circuit that includes only OUT1 and the Emergency Stop pushbutton, as follows:
a) From the 24VAC L1 fuse to OUT1 COM --> wire 503 RED, locations D3 and F1
b) From OUT1 to one side of one of the E-stop button NC contacts --> wire 509 RED, locations F1 and D5
c) From the other side of that NC contact to the contactor A1 terminal --> wire 536 GRN, locations D5 and B2
d) From the contactor A2 terminal back to the 24VAC L2 --> wire 502 BLU, locations B2 and B4.

When you talk of "the E-stop", you need to be clear when you are talking about the pushbutton, and when you are talking about the contactor.

Also, your diagram does not show two emergency stop pushbuttons. It shows the circuit for one button, in the control pendant or console. That one button is connected to circuits on the control panel via a 4-position plug. The plug connection has two sides: one side leads to the button in the pendant or console; the other side leads to various points on the control panel in the cabinet.

The emergency stop button has two circuits going through it, via two separate normally-closed contacts. That is why there are four wires through the plug. One circuit, with wires 509 and 536, carries 24VAC power to the emergency stop contactor coil. The other circuit, with wires 901 and 902, carries 24VDC to INP11 on the PLC.

Up early and got both push buttons that say "Emergency Stop" working correctly. Now on to tbe VFD. Since we have a spinde fault I am assuming that is why I still do not have a working coil on CNT1.

I followed this document...ignore where I penciled in VAC...it was late last night when I was trying to decipher l. I have checked this with multimeter as well as physically tracing it out.

The buttons work but the CNT1 24vac coil is not energized.

Am I missing something?

Look on the Alt-i screen.

If OUT1 is red, then the control is in a Fault condition.

If the control is in a fault condition, then the OUT1 relay will be open, and the emergency stop contactor will not close.

So yes, you have to address any fault conditions before you can expect your emergency stop contactor to close.

What kind of spindle drive do you have? What do you have wired to INP10 on the Allin1DC?
