8.2.3
Changing the Operating Range of Axis 3
At the factory shipment of a robot, software limits and mechanical stoppers are preset so
that the Z stroke of Axis 3 is between 0 and 150 mm (0 through 300 mm for Z-long
specifications). Fig. 8.5 shows the settings of operating range at the factory shipment.
If the coordinates of Axis 3 are moved to
the position of "-3.3 mm," the upper limit
mechanical stopper and the ball screw nut
will contact each other.
If the coordinates of Axis 3 are moved to
the position of "155.5 mm," the lower limit
mechanical stopper and the spline nut will
contact each other.
Mechanical stopper 155.5 mm
Axis 3 coordinates 150 mm
Axis 3 coordinates 0 mm
Mechanical stopper -3.3 mm
