I have 2 irb2400 m2004 irc5 robots that reboot during normal operation. sometimes they come back on but in a system failure state requiring a B-Start, other times it shuts down and shows "connecting to controller" until the power is disconnected and reset also needing a b-start. So far I have checked power supplies, changed main computers, the axis computer, verified Ethernet cables in the cabinet, and replaced the backup capacitor bank. I am running out of ideas on where to go from here
irc5 reboots intermittently

Halo
It sounds more or less as the same problem we had the robot works fine an then keeps on rebooting until you switch of the mains and sometimes it would reboot again or go to the Abb screen. We had a backup and we had a copy of the system on a usb. We had to do a C-start and reload the backup. The c-start wipes your system so dont do a c-start if you dont have a copy of your current system -

Sounds like a possible intermittent issue with incoming power on one or more phases. What was done to correct the 24V?

Are you still having the reboot issue?
If so, when you tried replacing the parts, did you put the originals back in after it didn't fix the problem?
Have you tried monitoring the incoming power? I've seen loose wire on the disconnect cause this. -
Can you associate it with temperature? Warm different areas and see if you can get it to reboot. You can also try cooling with freeze spray or use a can of dusting air turned upside down. I would start with the main computer.

HI all,
The cause of the problem is more than one thing.
First propose if you can downgrade the teach pendant software and upgrade after that.
Check the pendant cable, or if it possible replace for test.I think this is not a software problem.
70 percent of cases, pendant cable change soluted this problem.
The remaining 30 percent is software or main computer or pendant.BR/Attila

We have experienced the same kind of mysterious reboots and software crashes (hangs) on a new IRC5 controller. The reboots are random and don't seems to be tied to anything obvious. My gut tells me maybe it is caused by intermittent noise on the incoming power lines but I don't have any way to monitor them. We have had plenty of KUKA robots in the same building, using the same incoming power and have not seen this. But then again, KUKA controllers have backup batteries installed (not capacitors) so perhaps they are acting as a UPS.
