Error 20312 when attempting to jog the robot

Robot Controller

Hello,

We bought a used robot. When attempting to jog a joint via flexpendant I receive an error 20312 (attached image file)

Any idea what can be the cause of this?

Check all ethernet cables going from the main computer box, they are colored so they should be fairly easy to follow

-Check the cable from Axis Computer to Contactor board.

-Check the cable from Contactor board to Panel board.

-Check if the jumper for robot 2, 3 and 4 are OK in the Panel board.

I checked all the cables - tested them with a tester. They all worked fine. The only empty ethernet hole that I found was x20.

Is there anything else that might cause this? Perhaps external connections to the manipulator? (These were already connected when I 1st saw the robot)

Could I get a reference as to what I should check the jumpers against?
