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.
G23 is normally made active at power-up, though this is ultimately
determined by your system installer in AMP. Any zone that is activated in
a program or MDI block, remains active even after a control reset, E-STOP
reset, or end of program block (M02 or M30).
Important: If programming a G22, any axis words included in the block
are stored as the coordinates for programmable zone 3 (see page 11-40).
If an attempt is made to program some other command in a G22 or G23
block, other than a G code in the same modal group, for example:
G22 G01 X12.;
the control issues the error message:
“UNUSABLE WORDS IN ZONE BLOCK”
