Sorry for the cross post. Didn't see the Fanuc Subforum....

Hello,

I am adding a serial spindle to a Fanuc Powermate D (B501), and have the ladder written/modified and its basically working. Still working on getting the speed to work the way I want. The problem I am having is that when I give it an M05 it just coasts to a stop. I've reviewed other ladders I've written for other Fanuc CNC'c (16, 16i, 18i) and my code is very similar. I have tested that M05 is being processed by the PMC, but the spindle just coasts to a stop.

Any ideas? I've looked though all the parameters and can't find anything. I'm using a 6078 alpha spindle amp.
