kuka KRC1 restarts

[j3rry]

Hello
I have this problem my robot is restarting during loading cross when there is dark screen with robot and it loads first module then it start shutdown procedure...
then the screen with "you can now turn off computer..." and it start to boot again...

also batteries don`t kick-in when i turn the power down

I already check that batteries are charging (27V)
and the MFC card is good becouse I replaced it with second one..

some guy from service told me that this is PM6-600 and I have to replace it..
and my question is there any way to repair it or some way check it??

May be there is RAM problem in the PC, did you check the other component in the PC other than MFC?

Check your motherboard for Blown capacitors.
Clean RAM modules and reinsert.
Try reinstalling the KRC software.

Maybe some loose connections for PC Unit power supply.

Hi,

Let me clarify that I don't know the answer to this one, but I'm interested to follow you to the solution.

I'm just curious....if it was a capacitor, or RAM, or other M/B fault, shouldn't the PC just drop dead instantly? Logically, if there was a PC hardware problem, it should just power-off, not perform the whole shutdown procedure.

Yes, I guess it could be a KSS or windows problem.

And one other thought....I don't know if it exists, please advise. Is there a "PC-stay-on" signal somewhere? If there is and this signal is lost, it does make some sense...the windows have finished loading, they detect the absence of that signal and they shut down...exactly when the KSS starts to load. The timing matches. If there is no such signal coming from the cabinet, could it be a malfunctioning PC Power Supply?

I've seen this problem before.

I'm pretty sure it's a PM6-600 problem. I'm affraid you have to replace it.
Don't ask me what's wrong with it because I don't know  :-)

Maybe you can check the circuit board inside the PM6-600?

Good luck...
