I've been searching for an answer to this with no avail... Our machine has a PMDX-126, and I want to use the fault reporting of our VFD and servo drives. So far I have them working, by designating them as limit switches for axes we don't have (no conflict). But I would much prefer to see "Spindle Alarm" or "Servo Alarm" as opposed to "Limit switch triggered" Does anyone have a tip for this?

Yep Write some CB code for the macropump that monitors the inputs from the VFD/drives. If tripped then Estop the system and write a message to the OP advising of the error.  That way you know exactly what tripped the error.
