Hi all,
I have an LR15 with OSP5020L control. This morning after being on for 10-15 minutes, I got a "201-4 Alarm-A servo amp ZA-axis 2E6" alarm. No error led's are present in the back, but 1 of the drives has no led's at all. The other 3 have both PON and OP/SAOP led's lit. Is it dead? Rebuildable? Or is this even the root of the problem?

At the time of the alarm nothing was really running, I was swapping tools out of the turret for the next job.

Any ideas?

I swapped the ZA and ZB connections to see if the problem followed... nope, same drive still dead, and the alarm code and axis didn't change.
