KSS26012 Error in start-up mode for the fisrt time run of a new KR6 R900 sixxx

Good morning/evening to all of you,

I just finished installing and cabling a KUKA KR 6 R900 sixx (Kuka Agilus) robot and i am unable to move it. I understand that the X11 port must be wired so the robot can be moved but even in the "Strat-up mode" the robot does not move. The following error (KSS26012) shows up : "Ackn. General servo error (A6) - Originator : Drive". I also tried wiring the X11 port (pins 1-2 together and pins 10-11 together). See the joined photos.
How can i make this error disappear and be able to jog the robot in the start-up mode ?
Which of the X11 pins should i wire together to be able to use the robot out of the strat-up mode ?

Thank you.

First of all thanks to all of you for your responses. The error KSS26012 for me was caused by a "NOT WELL CONNECTED" X20 cable ! (See the photo) . The robot is jogging well in start-up mode. I will connect the X11 as in the schematics in the joined figure.

Thank you.
