System information

SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)
A coordinate system used to align the work part dimensions to the machine's programs is called a
work coordinate system. The work coordinate system is set by either of the following methods.
1. using a G92 command
2. using a G53 command
3. using G54 -G59 commands
4. using A G52 command
Work coordinate systems (G54 - G59)(G5#0…G5#9)
The dimensions of the work coordinates are always relative to the G92 Floating Zero Point. To
set a work coordinate system, press F7 (Parms) - F2 (Coord). The work coordinate menu will
appear allowing you to enter the offset coordinates for each work coordinate system. The Home
Position offsets are parameters which shift all coordinate systems relative to the Machine Zero
Point. Normally the Machine Zero Point and the Home Position are the same.
The following extended work coordinate systems are available.
G540 - G549
.
. (60 total work offsets)
.
G590 - G599
Note: G540 - G590 are the same as G54 - G59
G55 X1 Y1 moves to X1 Y1 in work offset 2
G59 X1 Y1 moves to X1 Y1 in work offset 6
G54 is always the power on coordinate system
Note: G54 - G59 offsets are not zeroed on power-up or after homing. The control will remain in
the selected coordinate system until another G54-G59 is executed.
Local coordinate system (G52)
The G52 command is similar to the G92 command in that it uses the current coordinate system
zero as its reference point instead of the current machine position (G92). When using the G52
command, think of it as “shift the work coordinate by”
X____ Y ____ Z____.
Notes on Local Coordinate System
Note 1: A G52 is modal; therefore it will affect all coordinate systems once set.
Note 2: To cancel a G52, enter G52 X0 Y0.
