Programming zone 3 values (4 or more 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
4 or more axes have been configured on the system (this does not include
any spindle).
This method differs from the three axis method in that the same integrands
can be used again for different axes (necessary since the control only
supports three integrand words). Assume the following AMP
configuration:
Primary Axis name X Y Z U V W A B C
Axis Integrand I J K I J K I J K
These axis words can vary. Refer to your system installer’s
documentation.
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__;
G22 U__ V__ W__ I__ J__ K__;
G22 A__ B__ C__ I__ J__ K__;
Where: Defines:s
Primary axis words maximum zone limits
Integrand words
(normally I, J, and K) minimum zone limits
Using this method, the same integrand word assigned in AMP to more than
one axis correspond only to the primary axis words programmed in the
G22 block. Integrand words cannot be programmed alone (without a
primary axis word in the G22 block). The following example assumes a
machine with axes configured as shown above.
