kuka krc2 indication of the robot stopped

  • Hello, I have for project the implantation of a robot kuka krc2

    The problem is that I only have the x11 party on the cabinet which can provide me with outputs. But is there an output in these outputs that indicates when the robot is at a standstill?

    So that I can use it for a PLC input

    Thank you

  • Define "standstill". There are many ways for the robot to be stationary:


    1. Program paused at a WAIT instruction

    2. Program halted

    3. Motors off / brakes engaged


    Also, what version KRC2? That defines what signals may or may not be available on the X11.

  • check AutoExtern configuration... there are system variables for robot moving and robot stopped

    X11 is a safety interface and should not have I/O on it. check your controller and see what is wired to it

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2

  • so if i cant use an one output on x11. I will have to add a card again?
    Because on the cabinet I only have this x11 output for cabled with peripherals.

  • All KRC2s came with a DeviceNet Master port (X801) on the MFC card. So if your PLC can support DeviceNet, you could use that. Or you could buy a cheap DN Slave I/O module, and wire that to some discrete I/O on the PLC.


    What I/O options does the robot have installed? Check the motherboard.

    this is not proper terminology which could be result of online translator or just lack of experience.

    X11 is just a pass-through-interface... a simple connector... no electronics or onboard intelligence... it could survive nuclear winter or hottest desert...


    "card" (EN) or "Klemme" (DE) refers to something that does have some sort of intelligent circuitry that provides some form of signal conversion between some bus and signals like I/O. this means some LEDs and electronics circuits, such as shown in pictures here:

    or

    Re: Wago and Beckoff


    nobody here can tell you if if someone did or did not bring such I/Os to X11. that would require opening cabinet end examining what is on the other end of the wires that reach X11 interface. if this is beyond your skill level, take some pictures of the X11 (front and back) and anything that connects to it. then we may offer some more suggestions.
