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. This allowed the Anilam 240V contactors to power up the VFD so it was able to report un-faulted. This is documented some more here:
