"Waiting for cyclic connection" error and "Emergency stop inoperative" on the smart pad

    Hello , I'm currently working on a KUKA KR30 2100 and CR4 controller , and I'm having some problems. I created a program with WorkVisual and sent it to the controller , but then the controller restarted, and since then, I can't connect to the robot. The smart pad shows a "Waiting for cyclic connection" error and "Emergency stop inoperative," and I can't do anything .

    The RDP setting doesn't show anything. When I try to send another program, it shows an error because I have to be in expert mode, but I can't access that since I can't do anything on the smart pad.

    Approved the thread.

    Get a monitor connect it directly to the control pc vga inside the krc4 cabinet to see if KSS starts at all. If so reactivate your last running WorkVisual project and do a complete cold start. If it is running you can activate expert mode. If this does not help restore the last valid image you took before this happened. Take a new image before doing this steps.

    How exactly did you get to the not working WorkVisual project? From scratch? By uploading a working project and modifying it and download?

    im just waiting for a monitor to teste now connecting directly to see what shows.

    i just created a new project and sent, i have not made any changes to the project

    I can see the programs that are in the robor, but i cant run them

    and if i try to send the program the other way is shows krl ethernet error

    Get the kuka recovery stick. Comes with a manual. Just need to boot from it and follow instructions on the screen. So basically the same way as any other imaging software but done with kuka usb stick and kuka recovery option bootimage installed on it. Needs to be purchased from Kuka if you do not have it already. Its highly recommended. If you do not yet have it buy it. Just to be safe in the meantime take a full archive and store your running WorkVisual project safely. These help restoring as well with expert knowledge but easiest way for beginners and fastest for beginners and experts is the kuka recovery with kuka usb option.

    thanks for the help, i have finaly been able to connect a monitor and with other user put the kuka in expert mode and send the previous prograng and finali solved my problem.


    Tanks for the help!
