Setup & Operation 5. Motion Range
G3 Rev.14 65
5.2 Motion Range Setting by Mechanical Stops
Mechanical stops physically limit the absolute area that the Manipulator can move.
Both Joints #1 and #2 have threaded holes in the positions corresponding to the angle for
the mechanical stop settings. Install the bolts in the holes corresponding to the angle that
you want to set.
Joints #3 can be set to any length less than the maximum stroke.
