6 POSITIONING CONTROL
POINTS
(1) Circular interpolation including the axis which set the stroke limit as invalid
cannot be executed.
(2) When the upper/lower limit value of the axis which set the stroke limit as valid
are changed, perform the home position return after that.
(3) When the stroke limit is set as valid in the incremental data system, perform
the home position return after power supply on.
(4) Do not use the high-speed oscillation in the axis that invalidates a stroke limit
of control unit "degree".
(5) The unlimited length feed is possible by setting the stroke limit to invalid even
the control unit is "other than degree axis" (mm, inch, pulse).
(Refer to Section 4.2.3.)
