Seems like a defect DSE. Shut down controller using the main switch and reboot.
Fubini
The only reason i can think of that another RDC would get damaged that way (and in more or less the same place) is that feedback cable for one or more axis is defective (punctured, worn out etc.). If the internal robot harness was not routed correctly (too tight, too loose, was rubbing on something foreign, etc.), it could get compromised and trigger failure.
for example if insulation was rubbed off exposing conductors, and then robot moves so that the sore spot (jacket abrasion) reaches something else, it would short and fail.
have the same errors, the robot stopped in the exact same place as the first time.
More information on that would be very helpful - exact place
i recall doing some preventive maintenance on couple of 2000 series robots (KR150 i think). Once the black skirt around the robot base was removed to lube the harness, i was amazed to see numerous foreign objects. There was more than 10 pretty large metal chunks (several taps, drill bits of different size, one huge bolt some 20mm in diameter and maybe 230mm long etc.) and whole bunch of smaller ones (self tapping screws, washers, ...). several of them including the head of the big bolt was stuck into side of the plastic tube protecting harness and were riding along with it when ever A1 would move. And that was metal junk found in just one of the robots.
