Programmable Zone 3
This area becomes Programmable
Zone 3 if the zone is enabled
when tool is inside of this area
Programmable Zone 3
if enabled when tool
is outside of this area
Programmable zone 3 becomes active when either the G22 or G22.1 code
is executed. It is made inactive when the G23 or G23.1 code is executed.

these zones:
G22 2 and 3 not applicable
G22.1 3 2
G23 not applicable 2 and 3
G23.1 2* 3
* A G23.1 only turns on programmable zone 2 if it is
activated via a control reset or power up condition.
G23.1 does not turn on programmable zone 2 if it is
programmed. To turn on programmable zone 2 and
turn off programmable zone 3, first program a G22
followed by a G23.1 to turn off programmable zone
3. Programming G23.1 has no affect on zone 2.
G22.1 and G23.1 are modal (G22.1 cancels G23.1, and G23.1 cancels
G22.1).
Important: G22.1, G23, and G23.1 must be programmed in blocks
without other commands. If you program a G22, any axis words included
in the block are stored as the coordinates for programmable zone 3.
