Dear Sirs,

I have a new problem with a KUKA KRC2 cabinet.

Today, after switch in, the boot process stopped at the loading step ( on the screen: "LOADING" )

I tryed several times to switch in the robot again,but the result was the same. Stop at "LOADING..."
I changed the memory card, the result was also the same.
After them I installed the windows and KSS again, first time the boot process was succesfull, but by the second start ( cabinet off, cabinet on ) the problem came again.

If somebody have any idea, what is it, I would be grateful for the help.

Thanks a lot in advance.

So, you:

Replaced the RAM
Re-installed Windows and KSS from the install CDs

If the problem is still occurring, the next items on the suspect list are the motherboard itself, and the hard drive.  You might want to remove the hard drive, connect it (via IDE-to-USB converter) to another computer, and run a sector scan on it.  Or, simply replace the hard drive with another, compatible, unit, and perform a fresh install of Windows and KSS.

For the motherboard, about the only thing to try is swapping it with another unit.  You can also try visually examining the motherboard for any obvious issues -- scorch marks, swollen capacitors, etc, but most of the time motherboard hardware issues tend not to be visible to the naked eye.

Thank you for the prompt reply,

RAM changed,

In the PC is a 4GB Flash Module.

Another issue, that the button battery from 2010...but I don't know, can it cause so a problem, or not...

On motherboard I do not found any mechanical lesions.

In the installation process it was a strange thing , KSS installer said :

that battery need to be changed every 5 years so... it's been dead for years.
when you replace it load KUKA default BIOS settings and save them.

Ok,
Before battery change should I save out any info from BIOS, or simply use all default parameters ?

Nope...!


battery is required...

It provides power to CMOS RAM, which is where the BIOS settings are stored. Without correct settings, PC may work... but not correctly. without it, PC is not functional. installing software on a not-functional hardware is ... not smart (most likely just waste of time).

As soon as you switch power off, CMOS RAM is going to be corrupted again (unless CMOS battery is good).
So saving settings with no battery (or with DEAD battery) is pointless.

Thanks for information,

I changed the battery at now, and the next surprise :   

The servo drives, the power, 24V, cooler fan - all works , but the PC do not starts....

It's very interesting, the Interbus PCI card LED are on, but the PC do not moves. Not inside fan, not the display.....nothing... :(

well... what happened exactly? did you pay attention to ESD measures? is everything connected back the way it should?


assuming everything is fine and this is just result of battery replacement, check YOUR motherboard manual for POWER_ON button info. it is normally on a 0.1" header with bunch of pins. you need to find the pair for POWER_ON and briefly short it (without touching anything else), then get into BIOS, load defaults and save them.

Here is an example for one motherboard:
