Gonna be a warranty/replacement part claim to UR I think. Had something happen to ours recently too. Ended up being the Power Supply Unit that went bad. UR Tech came out, swapped it, and we were back up and running. It’s either that or the Safety Control Board ---

All the more reason to get someone to fix it, while there is still warranty. 🙂 It does sound like faulty hardware. Contact your local UR distributor, and they should handle it. ---

The problem I described happened to our robot with 0 on time. Couldn’t boot it fresh out of the box. So yes, get it serviced by a UR Tech / Distributor
