Connection IOs between Kolver EDU 2AE/TOP/NT/TA and UR 5e?

Hello!

I am currently working on integration of robot screwdriving application that involves using a Kolver 2AE controller and UR 5e robot. I would be really grateful if someone can help me with the electrical connection process.

In my case I have to connect all the pins from Kolver’s CN1 connector to the UR robot and also pins 2, 11, 12, 13 and 14 from Kolver’s CN2 connector. In the following images I am sharing the tables and schemes for the connectors.

I understand how I should map the IOs between the control units, however I have a little problem with how to ground everything the right way.

I would be grateful for any advice that you could provide me with! Thank you in advance.

Best regards,
Aleksandar
