I have an ABB IRB6400R with S4C+ M2000 controller.
I had to replace the main computer module, the slide out cabinet because It was showing CPU overtemperature.
It would boot up ok but after 10 seconds it would shut down and then give this message.
I took the unit to my workshop wwhere I have several of these systems in storage, I use these sometimes for testing.
I fitted this module into a known good robot system, and the error followed the module. I am happy the error lies within the module.
I have several spare computer units so I set one up to test and got it to run ok, starting up without any issues.
Took this unit to site and fitted it into the robot and set it up and it ran fine for hours, working as you would expect.
It then suddenly locked up, the EN light went out and the system was totally unresponsive, not showing any error, not responding to any TP buttons or the MAN-Auto Key switch.
The STATUS and PWR indicators on the CPU board were solid green.
After cycling the power the robot would not complete the power up. PWR indicator would illuminate green,
after about 5-10 seconds the HDD indicator would flicker for about 2 seconds after which the STATUS indicator would flash continuously at around 1HZ.

After 10 to 20 minutes there was no change. Tried restarting several times but without success.
I had another computer module, I fitted it and set it up and it ran all day yesterdayfrom around Midday up until about 20:00 and the same thing happened.
I also replaced the Power supply module before I fitted this computer module, just in case.
I am puzzled. Can you give me any idea of what this could be? I would greatly appreciate any comment. Thanking you in advance.
