Hello. In the power panel, the two cards with the green and red leds. I don't have any manuals that tell me what they indicate. Both of them are on on both the Y & X boards.

I am having an issue of negative readout being displayed but when moving positive, no displayed readout.

When jogging from the controller the same thing happens, but when moving positive, it alarms as runaway.

Any help with a manual or direction to troubleshoot would be appreciated.
