Technical Questions

I’m encountering an error with the UR5 with a C4A14. When I enter PolyScope Expert mode to the Low Level Control it shows that
Join 0 and 1 are in Bootloader mode but all the other joints are offline. When I remove the covers on the side of the joints it appears all of them are getting power and signal.

I’ve also tried replacing the safety board and updating the software without any success.

Hi,
please reach out to the integrator/distributor where you have bought the robot.
They will setup a support case and have more options to provide direct support here.
