Programming zone 3 values (3 or less axes)

You can reassign values for the parameters that establish programmable
zone 3 by programming axis words in a G22 program block. Two methods
are available. This section discusses programming values for zone 3 when
3 or less axes have been configured on the system (this does not include
any spindle).

Define values for programmable zone 3 using the G22 command followed
by axis words in the following format:

G22 X__ Y__ Z__ I__ J__ K__;

Where:

Defines:s

Primary axis words
(normally X, Y, and Z)

maximum zone limits

Integrand words
(normally I, J, and K)

minimum zone limits

These axis words can vary. Refer to your system installer’s
documentation.

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.

If the same integrand word is assigned in AMP by the system installer to
more than one axis, that integrand word will set the lower zone 3 limit for
all axes with that integrand.
