Page 20: O Control
3 I/O Control The I/O mode is a common control method in industry. The grippers will monitor the pin states of Input 1 and Input 2 (0V and high resistance states). For these two pins, there will be four logic states:00,01,10,11. You can control this gripper through changing the states of Input 1 and Input 2. -
