Link the Universal Robots' e-stop to the Gripper's power supply

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.
