have problem with irb2400 robot 5axis

If you had a safety chain fault none of the axes would work.
Does that model have a brake release?, if so, release the brake on axis 5 and check it moves freely by hand.

Solved: Harting connecting pin was broken.

Glad you found the problem.

We had a same problem with 5 and 6 th axis. Finally the technician came a change the sensibility of this axis.

I can show you the parameters because the technician did not show me.

This values are betwen 1 and 10. We had all axis in 1 level. The 5 and 6 th axis be changed to 3.

If i can found the values, I type for you. Sorry

First i try to remove wrist, thinking that its could be broken, but its ok.
also try to experiment and swap 6 and 5 axis motor. the problem are the same even with the another motor.

the robot was in working condition until I move it to another place.about30 meters, maybe I disconected something of safety chain?
