Tom,
So you are killing the AC power when you hit e-stop. If you are using the C23 and have enabled the Safety Charge Pump, you can use pin 17 for that. This should not blow the fuse. Have you talked to Larry? I am sure he can suggest something. This sounds like a problem with the power supply.
On large machines I always recommend users to not leave the limits and e-stop at software control. Our boards come with an external enable terminal marked EN. You can use that to connect e-stop and limits to have these disable the outputs and stop the machine at hardware level.
