Ugh... I realized I was trying to reply on this thread from a different
email account and the mails didn't come through. In any case, I ended up
solving this with a classicladder program for estop and a separate one to
delay the spindle fault estop signal until one second after the machine was
on.

I am working on the finishing touches of an Anilam 1100 knee mill
conversion to EMC2, with details here:

Over the last couple of months our spindle VFD (a Compumotor SpindleBlok)
has faulted 5 or 6 times (a description of that partic
