Hello guys,
Yesterday i was testing a Kuka Robot for commissioning, a KR 470-2PA, KRC4 Controller
Everything was good at the beginning, in Start-up mode, i was able to move the robot, test I/O signals from the tooling, check programs, points, everything. After a couple of hours i tried again to check some programs, and motion was not possible, even in start-up mode, with the Robot disconnected from the PLC, i restarted several times the controller with the same result.
One strange thing that i noticed was that the "key" for change between T1, T2, Auto, External, it wasn't showing anything on the screen when i was moving it. Also when i hit the Emergency stop of the Teach pendandt, none message was on the alarm history about emergency stops.
I am a little bit lost with this, because i went for lunch, and when i returned the robot was not moving anymore :(.
What should i check? Try a different pendandt?.
Cheers!
