Now I prepared the X11 service jumper plug as per kuka manual ,but what is the safeguard connection about ? pin7 to pin25
safeguard is for wiring operator safety. usually this is cell doors circuit.
i am also a bit nervous reading your posts and numbers... not sure how you came up with 7-25. and i hope you did not connect 7 to 25.
there need to be closed circuit on channel 1 (X11.7 to X11.8) and channel 2 (X11.25-X11.26).
