KUKA Not moving!

Maverick · 2022-06-13T18:06:55+02:00

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!

CCU has a lot of things on it... power distribution, managed switch, high speed inputs, safety node (for enabling switch, mastering reference switch), etc. on compact controllers it also integrates entire SIB. considering complexity it is remarkable how rarely it need to be replaced.
1) read pinned topic: READ FIRST...
2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly
3) read 1 and 2
