Overtravels and Programmable Zones

Using this method, the same integrand word assigned in AMP to more than
one axis correspond only to the absolute axis words programmed in the
G22 block. Integrand words cannot be programmed alone (without a
absolute axis word in the G22 block). The following example assumes a
machine with axes configured as shown above.
These blocks: Results in:
G22 X10 I--10 Y14J--14 Z1 K--1;
G22 U5 I--5 V13J--2 W11 K10;
G22 A3 I2 B7 J--7 C12K11;
upper andlower zone 3limits for all9 axesare
changed. Zones 2 and3 are both activated when
the first block in thisseries of blocksis executed.
G22 X1 Y2 Z3 U4V5 W6A7 B8C9; upper zone3 limitsare changedfor all 9axes.
Zones 2and 3are bothactivated.
G22 X1 Y2 Z3 U4V5 W6A7 B8C9 I--1 J--2 K--3; upper and lower zone3 limitsfor all 9axes are
changed. (I sets lower for X, U, andA: J sets
lower for Y, V, and B: Ksets lower limitsfor Z, W,
and C). Zones 2 and 3 are bothactivate.
G22 K--10; error isgenerated. Current status of zones
remains incurrent state (onor off).
WARNING: When using multiple blocks to set the zone 3
limits, keep in mind zone 3 is activated after the first G22 block.
This will result in zone 3 being activated before you have
completed changes to the zone 3 values. This can cause the
control to miss-interpret zone 3 as an internal or external zone,
depending on the tool location at the time of the zone activation.
The zone values entered in a G22 block always reference coordinate values
in the machine coordinate system.
If a value for a maximum axis parameter is less than the value set for an
axis current minimum parameter, or if a value for a minimum axis
parameter is set greater than the value set for an axis current maximum
value, the control displays the message:
“INVALID VALUE (MAX < MIN) FOR ZONE 3 AXIS (X)”
This message displays the name of the axis that has been set incorrectly. It
does not indicate if it is the minimum or maximum value that is incorrect.
