Hey everyone,
My machine keeps going into drive fault at the end of jobs, right after the spindle raises in the Z axis. This happens with about a third of the jobs I run, it happens inconstantly even when running the same exact job back to back. At first I thought it might be something to do with the Z axis travel, but then today it happened right as the spindle was slowing down after a spindle warmup. I got the message on the screen that the “warmup is complete”, and then the spindle began to slow down and the machine went into drive fault. When it does this, I reset the fault and try to jog the machine but as soon as I try to jog it in any axis it immediately goes into drive fault again. I’ve been having to shutdown and restart the machine every time this happens, and then when I start the machine up I can jog it around no problem. I have a AV40s spindle and a EX controller.
Any help is appreciated thank you
