This area is determined by the current wheel location when programmable
zone 3 is made active.

Programmable Zone 3
This area becomes Programmable
Zone 3 if the zone is enabled
when wheel is inside 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.
Programming
this G-code:
turns Zone 2: turns Zone 3:
G22 On On
G22.1 Off On
G23 Off Off
G23.1 No Change* Off
* A G23.1 turns on programmable zone 2 if it is the default
power up condition configured in AMP (also activated at a
control reset). G23.1 does not turn on programmable zone 2
when it is activated in a part program.
You can reassign values for the parameters that establish programmable
zone 3 by programming axis words in a G22 program block. Main axis
words (normally X and Z) define maximum zone limits. Integrand axis
words (normally I and K ) define minimum zone limits. These axis words
can vary. See documentation prepared by your system installer.
