5-6. Coordinate Systems Used with the Teaching Feature
3 Use to
move the X, Y, and Z axes to the location you
want to make the optional origin. Press
.
This registers a single optional origin. To cancel and re-
turn, press
instead of .
4 Repeat steps 2 and 3 as to register a second
and third optional origin. When you're done,
press
several times to go back to the top
screen.
I Level and R Level
These are special points used for positioning the Z axis. You use them only with the teaching feature. They are used with
the [MOVE-ZI], [CUT-ZM], and [CUT-ZI] commands. When you use any of these commands, you need to register the
I level and R level in advance.
The I level and the R level both take the Z0 position as their reference point. If the Z0 position changes, the locations of
the I level and R level also change accordingly. Also, selecting an optional origin in a sequence using the [SEL ORG]
command makes the I level and R level change to locations that reference the selected optional origin.
Using these makes it simple to change such things as the distance for operating the Z axis at the highest speed, and lets
you make fine adjustments to perform operations with less wasted effort. This can help make for efficient cutting as a
result.
Registering the I Level and R Level
1 Press several times to display the screen
shown at right, then move the blinking cursor
to [TEACHING]. Press
. Move the blink-
ing cursor to [SETTING], then press .
2 Press several times to display the screen
shown at right. Move the blinking cursor to ei-
ther [I LEVEL] or [R LEVEL], then use
to raise or lower the value.
This value indicates the number of steps above (positive
value) or below (negative value) the Z0 position. As with
coordinate values, one step is 0.01 mm.
3 Press .
The I level and R level locations are registered.
