Parameters (Nos. 1322, 1323) or commands set these boundaries.
Inside or outside the area of the limit can be set as the forbidden area.
Parameter OUT (No. 1300#0) selects either inside or outside as the
forbidden area.
In case of program command a G22 command forbids the tool to enter
the forbidden area, and a G23 command permits the tool to enter the
forbidden area.
Each of G22; and G23; should be commanded independently of
another commands in a block.
The command below creates or changes the forbidden area:
