Hi Pros,

I wanted to share with you how to configure Robotiq's 2-Finger Gripper on a UR so that it loses its power when the e-stop button is pressed. Here is how I do it: 
  • Instead of connecting the 2-Finger Gripper's red wire to a 24V pin, I connect it to a configurable output. In this example, I connected it to configurable output 0 (CO0). 
  • I connect the rest of the wires as described in the instruction manual

  • On the UR teach pendant, open a Robot program and go in the Installation tab. Click on Safety and enter the password, if required. 
  • From the Safety I/O tab, change the function assignment of the configurable output you connected the red wire to. Change it to System Emergency Stopped. In the example, I changed CO0 and CO1. 

Performing this will cut power to the gripper when the robot's e-stop button is pressed. When it is restored, the gripper will get power back again. Remember that you will need to activate the gripper since it lost power.
