I am purchasing a new Fanuc robot (Model: M-710iC/70). I have been thinking about the design for the pneumatics that will govern the actuator to open/close. I am concerned with what will happen if/when the air pressure is lost. Naturally, I do not want the part being gripped to fall out of the gripper if air pressure is lost. I am thinking of using a set of pilot operated checks to help mitigate this scenario. I am wondering how others have dealt with this potential scenario. A portion of my schematic is attached.
Thanks
