Protective stop while auto moving to start point

Hi there, here is some question what a little scare me because it happens time to time then I hold “auto” button and moving robot to the first position.

This UR5 standing at the solid welding table.

May it be a defect of a robot?

Hi @stim48,

That is odd that this happens while you’re holding the auto button. This type of protective stop normally happens when you try to tell the robot to do something “insane” like an extremely aggressive change in speed.

Could you share more info about the physical scenario that causes this? It could be that the robot is close to singularity (but I’d expect it to switch to a movej if that was the case).
