5.4 Standard Motion Range
The following “motion range” diagrams show the standard (maximum) specification.
When each Joint motor is under servo control, the center of Joint #3’s (shaft’s) lowest point
moves in the areas shown in the figure.
“Area limited by mechanical stop” is the area where the center of Joint #3’s lowest point
can be moved when each joint motor is not under servo control.
“Mechanical stop” sets the limited motion range so that the center of Joint #3 cannot move
beyond the area mechanically.
“Maximum space” is the area that contains the farthest reach of the arms. If the maximum
radius of the end effector is over 60 mm, add the “Area limited by mechanical stop” and
“radius of the end effector”. The total value is specified as the maximum area.
