I have a new (has had power on for about a week, right out of factory) IRC5 Controller running an IRB660. Yesterday found an issue with temp sensors on drive 1, also throwing overcurrent alarms at times. That turned out to be a loose R1MP plug in the back of the robot. We plugged it in nice and snug and power cycled. Right after the power came on again, we got issue 90819 "Voltage Test Failed". Because the robot has safe move basic, this opens the superior stop and the robot is unable to move.
We have checked all the plugs and harnesses in the robot, and swapped the safety board with another robot we have straight from the factory too. We've also swapped the R1MP cable to see if something was wrong in there, the issue remains. Has anyone seen this before?
