What happens if you just turn the shutdown switch on the controller without selecting shutdown option from the KSS menu? Usually that is the rightway to shutdown KRC2 controller. There is no need to first choosing the shutdown menu option. With shutdown option choosing from the KSS menu, the controller just reboots. If I can remember correctly, it has been always like that.

When I turn the key switch, the system does shut down — no issues there. I had just assumed that doing it that way (without using the KCP shutdown menu) might be harmful to the mechanical DOMs or IDE HDDs, since it felt like cutting power without giving Windows a chance to close things properly.

That’s what led me to believe there must be a more “correct” or graceful software-based shutdown method, which is why I came here to ask the great and all-knowing minds of this forum!

Sounds like maybe I was overthinking it — if the key switch is designed to signal a proper shutdown sequence internally, and Windows handles it cleanly, then I guess that really is the intended way.

Thanks for the clarification!

Thanks for the reply!

Yes, to clarify — right now our shutdown process is:

1. Press the KCP “Shutdown” softkey (not the Windows Start Menu).
2. Wait for Windows XP to fully shut down (black screen, no drive activity).
3. Then we turn the cabinet key switch to OFF (0) to fully cut power.

If we don’t throw the switch quickly enough after shutdown, the KRC2 logic reboots the PC again, which is what we're trying to avoid — mostly to protect the old mechanical HDDs from power cycling stress.

We were hoping to configure the system to stay off after shutdown, so we wouldn't need to rely on someone manually throwing the switch every time. But it sounds like, based on what you said, that’s just how KRC2 systems work until at least KSS V7 — the PLC sees the shutdown and re-applies power unless the key is off.

Hi all,

I’m working with a KUKA KRC2 robot running Windows XP, and I’m trying to configure it so that when I issue a shutdown from the KCP, the system stays powered off. Currently, every time I shut it down (using the KCP or Windows), the controller powers back on automatically within a few seconds.

Here’s what I’ve tried so far:

• Checked the BIOS for “Power On After Power Loss” or auto-boot settings — nothing relevant found.
• Used the ColdStart.reg file from C:\KRC\UTIL\REGISTRY\, but the CCU\Startup key doesn't exist in the registry.
• Manually created the missing registry path:
  HKEY_LOCAL_MACHINE\SOFTWARE\KUKA Roboter GmbH\CCU\Startup
  and added ReStartType=0 as a DWORD (hex) value.
• Enabled “Cold Start” and “Disable Power Off Delay” in the KUKA HMI On/Off Options.

Despite all of that, the robot still reboots automatically after shutdown unless I physically turn the cabinet key switch to OFF (0). Ideally, I’d like to be able to shut it down remotely or at least via software only.

Has anyone successfully solved this behavior on an older KRC2 (non-ed05) system? Is there a hardware jumper or relay I’m missing that causes the PC to repower?

Thanks in advance for any insight!
