Coordinate Control
Chapter 11
11-42
For example, the following block:
G22 X10 K2;
redefines the maximum X coordinate of programmable zone 3 at a value of
10, and the minimum Z coordinate of programmable zone 3 at a value of 2.
Any unspecified axis parameters remain at their currently defined value.
The coordinate 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 whether it is the minimum or maximum value that is
incorrect.
Important: You must program G22.1, G23, and G23.1 in blocks without
other commands. If programming a G22, the control stores any axis words
included in the block as the coordinates for programmable zone 3.
If other commands are programmed in a G22, G22.1, G23, or G23.1 block,
other than a G code in the same modal group, the control issues this error
message:
“UNNECESSARY WORDS IN ZONE BLOCK”
For details on how the control reacts to entry into a overtravel area, see
page 11-43.
