PDMX 126 with AM822 drivers and relays.

[JAZZCNC]

JAZZ, most of my faults have been detected by controllers etc, but regarding the 882 error loop..... Do you know, or does anyone know 100% that it is the main motor DC power that needs to be cycled in order to clear the fault?

You have two choices to clear the Fault. Recycle power to the drives or use the Enable input.
To use the Enable input for a reset you'll need to set it up in the software. Then setup a Drive Reset button which cycles the Enable input.

Like has been suggested most use latching circuit because it's safest approach and kill power so the drives get reset by default so not an issue.

Take your pick.!
