Your system installer can also turn zones on and off with PAL. Refer to
your system installer’s documentation for more information.
For details on how the control reacts to entry into a prohibited area see
section 12.5.
Important: G22.1, G23, and G23.1 must be programmed in blocks
without other c ommands. If programming a G22, any axis words included
in the block will be stored as the coordinates for programmable zone 3.
Programmable zone 3 can define an area which the tool may not enter or
exit. Generally, zones are used to protect some vital area of the machine or
part located within the software overtravels.
Important: Programmable z ones are defined using coordinates in the
machine coordinate system. They are not
affected by any changes in the
work coordinate system, including external offsets. They do however take
into account any active tool offsets.
Values for programmable zone 3 are entered either in the programmable
zone table (discussed in section 3.5) or through a G22 program block. A
maximum and a minimum coordinate value (in the machine coordinate
system) is assigned for each axis. The resulting coordinates define the
boundaries for programmable zone 3.
