Odd programming?

I am cutting some plate for parts on my Bridgeport conversion project, had some good success and a couple of oddities. The most annoying one is my motor VFD has shut down twice now with an error that shows as short-circuit on motor phases, each time i reset and it carried on ok, there was a month between faults - the annoying part is i don't have the fault relay in my e-stop loop (yet) so the motor quits and the motion caries on - snap goes another £8 tool :(

The rest of my issues are experience, or lack of, related so in the end i worked them out, but I'm getting pretty good at re-homing and starting over with modified code ;)
