When a new tool is mounted, position the tip of the tool on the two corners
of the limit area, and specify the machine coordinates of the corners in the
parameters for stroke limit 1. The machine coordinates are stored in the
CNC as the limit positions. Then input signals for setting the stroke limit.
Stroke limit setting signals are provided for each axis and each direction.
Checking of the stroke limit can also be selected by turning on or off the
limit release signal common to all axes.
