Hi community,I have previously connected multiple grippers using EtherCAT using KUKA iiwa robots. Usually no problem.I had this configuration saved, and everything was working well until last two days, the gripper constantly shows the red static color. The EtherCAT box says there is no error and I have changed and connected other similar grippers that immediately display the blue color as soon as I connect them to the same coupler. Strange.It leads me to believe there is an error with the gripper internally. How could I fix it? Is there anybody out there with an advise for me?Thanks,Walter.
