It looks like the E-Stop on that board comes out to a relay, that is a good thing as it means you can do several things with it such as conecting as mentioned previously.
For example it would seem your relay has both normally open and normally closed contacts, so the normally open can feed to the  stepper drives enable inputs and the normally closed can feed to the ESS input as an E-Stop input. You can also put your other E-Stop switch in the chain just by connecting it in series with that relay.

Hood,
The C25 break out board doesn't have an enable terminal.
stepper drives enable inputs?  Where is that at?
A while back, I touched on this subject with Arturo, and these are his replies:
Mike,
Please note that the original wiring diagram for your machine showed e-stop as removing power to the entire system. We did not change that, as that is how the original equipment manufacturer designed it, and I do not like changing this without been familiar with the machine.
In this case, I would suggest that you connect the enable in series with the existing e-stop button.
Please verify that power consumption of the system does not exceed the ratings of the relay.

Hood, here I was referring to the wiring instruction for the C22 pendant interface board. And here is Arturo's reply:
Mike,
This wiring diagram does not apply to the C25 as the C25 does not have an external enable terminal.

Hi rcaffin,
The ferrites I show are on the home switch wires. The reason they (wires) look messy now is, because on the picture the the ESS is missing, and the wires are just hanging there. There is one thing I don't understand:

No, dressing the power wires together is not just 'pretties', it does help.

I am meaning the enables on your stepper drives. They really should be called Disables as when they are left unconnected the drives are enabled, that is why you could use the Normally Open contact on the E-Stop for them.

Hood,
Now I kind of understand. What I really need is, for this wiring to be shown on the Jinan2 diagram. Is that possible?

Do you have a version of that wiring diag that can be edited?

Yes, there is a R2010 ASCII.dxf file, it is 18.1MB, and a .dwg (Autocad) that is almost 30MB. How can I send one to you?

Hood,
I can compress it down to 872 KB as a .rar file, but i think it'll only work if I send it in an email.
Mike

PS. It did go thru on this forum.

Ok I have tried to open but my cad is a PITA with large dxf's.
Is the C22 in that dxf?

No Hood, I inserted the pict of the C22 terminals into the drawing, tried to send it to you and the forum didn't accept it. I use DrafSight, ( a vector program) it is very similar to Autocad that I know. It is a free program, I downloaded it from the internet. I'll rename the rar file and try to send it again. Last year you gave me your email address to send a large file over to you. But I'll try to attach it to this message.
