I am planning the electrical connections (first time) to a KUKA KR6 robot that has the AIR CTR GIG connection configuration.
The robot has 2 pneumatic valves (5/3) and 4 digital inputs avaliable.
I thought that in order to connect to these inputs/outputs (that will be monitored/controlled with an external PLC) that the connection goes through the robot. I thought that we will connect the cable from the PLC to the robot to a connector on the base of the robot (but as far as I saw in the user manual the only connector that goes from the base of the robot to the end of the robot arm is the GIG connection (X74). Is this correct? Do we really need to guide a cable to control/monitor the available valves and inputs on top of the robot? Am I missing something?
I just looked throgh the manual and one explanation could be that the solenoids and digital inputs are controlled/monitored by the robot controller? We just wire the end switches from the griper to the avaliable digital inputs on X41?
I hope that I explained so that you understand what I mean.
Thanks, in advanced for any information.
