Hello,
I have a UP6/XRC welding robot that after done a welding routine go to home position, stays at home position for a millisecond, and the T axis “slides” out of home position like 15°. Then when I tried to run the next welding routine it gives me an alarm 1326(defective encoder absolute data), I reset the robot and then I am able to set home position and run a few times the robot until come to home position error again.
