4680 - Accessor Y motor did not move

The Y motor on the robotic accessor did not move. This could be caused by a motor cable not being fully seated, a robot cable being improperly plugged, or damage to the Y motor or drive electronics on the robotic accessor. This fix procedure describes how to diagnose and correct this issue.
