3.6 External Wiring and Piping Box
The air hose that is connected inside the robot, the optional hand output cable, the hand input cable, etc., can all
be pulled out from the rear of the No. 2 arm.
These can be used to connect a customer supplied solenoid valve to the hand output cable, etc.
When using this option, J1 axis operating range is limited ±120 degree. And a stopper for changing the operating
range option is required.
