I wired this up this morning to ensure if there is a drive fault it will stop the program from running/crashing. All of the drives are wired as per the instructions (pmdx provided) and I will try to explain how I did that to the best of my typing abilities. I have a wire going from the PMDX126 ERR+ to my Z drive +5V. I have a wire going from the PMDX126 "COM" to the Z drive +5V. I have a wire coming from the PMDX126 "RST" and another wire coming from the PMDX126 "ERR-" to a soldered joint which splits 3 ways to go the each drives "ERR/RES" terminal. When I manually get a line count fault to fault the drives the PC/Mach III see the error on axis Y and Z but not from X and will also reset the Y and Z drives but not X. I have CONFIG on the PMDX126 to have terminal 1 and 7 to OFF and the rest ON. In Mach III I had the E-stop enabled to pin 10 already and added the "enable charge pump" to pin 17 active low with a red X as per the instructions. I have gone over the drives to make sure they were setup the same and they are. I verified the wiring and I see no difference with the X wiring versus any of the others as they are jumpered together. Any thoughts?

I should add that if I swap the reset wire to a different drive the problem stays with the drive and not the reset wire. I have an E-mail in with Gecko but I am guessing the problem is there.

I agree that the issue may be with the drive.
You might test the drivers one at a time to be sure there are no interactions.
I am not sure you can mix the old G320 and the new G320 on the same
reset circuit from a PMDX-126.
