(1) This command positions the specified axis from the current position to the second
home position through the specified mid point at the rapid feed rate.
Current position
(2) Be sure to set the axis which executes the second home position return. The
second home position return is not executed without setting.
(3) Be sure to set the mid point coordinates.
(4) The mid point data setting can be made by direct setting (numerical value) or
indirect setting (variable : #
(5) The tool length offset and virtual mechanical coordinates (Refer to Section
7.13.29) of the axis which executed the second home position are cancel.
Mid point designation depends on the position command system (G90, G91)
currently selected.
(6) When the control unit is [degree], operation from the mid point to the second home
position differs between the absolute value command (G90) and incremental
value command (G91).
The axis travels in the nearest path under the absolute value command (G90), or
in the direction specified in the home position return direction parameter under the
incremental value command (G91).
Second home position address : The current value of the second home position is set.
