Hello, I have a IRB6400 M97, its throwing mainly 2 errors but the joints change. I cannot get any of the joints to move as they throw these errors. I cannot manually move them either via the brake buttons. There is no click at all.
Error 50056 - Actual torque on Joint IRB_4 is higher than ordered while at low or zero speed
Error 50021 - Actual position of joint IRB_3 is too far away from ordered position
I have tried to look at previous threads about checking the KM3 contactor. I don't see this anywhere I assume I have a different year/model.
Any help on this is greatly appreciated.
