Hello, I have a robot that keeps losing comms at the same position every time. What I am going to try and do is reprogram so it avoids going to this position. Right now it's a MOVJ P105, can I change that to a linear position? What can I do to avoid this one position until we get a new servo in the robot? What is happening is I think the brake is wore out on the servo so it's losing track of where it's at; gravity it pulling it down.
Robot stop in same position every time

Is P105 out in space? Sounds like the orientation of the robot is wearing the harness. Pulling the harness apart due to extended out or crouched back.
Yes, you can change from a MOVJ to a MOVL. Test to see the new path. Depending on where the robot is vs. P015 the arm could try to run the tool into itself.
If the brake is worn, on a few year old robot, the arm may drift when servo power is off. Worse case, depending on axis, an out of range abso data or drop value alarm. Neither are a big deal.

Hi 95 Devils,
Yes, I get the out-of-range abso data or drop value alarm each time I the encoder loses comms. I have found this to be happening so much that it's making the robot almost useless. I can't figure anything else out but to have the servo changed out. Do you think this will solve the issue? We stack boxes 9 layers high it gets the ENCODER comms loss in the same spot every time on the 9th layer. This is killing production and killing the backs of the people that have to hand pack while the robot gets rebooted. Also, would it be wise to change the harness at the same time as the servo just to eliminate that?

Please do one at a time (like the harness first) or you will never know what the problem was.
