2.3 Teaching function
The teaching function is used to teach the machine position such as XY coordinate values using a teaching unit
(camera or head). There are two teaching methods: "point teaching" and "cursor teaching".
2.3.1 Point teaching
Point teaching is further divided into "one-point input" and "multi-point input". The "one-point input" allows the
teaching data to be directly entered. The "multi-point input" gives the center coordinates in the multiple
positions which are specified by teaching.

Clamp a board on the conveyor.
2
Set the trace conditions.
Set the "teaching unit", "speed", and "fiducial correction".
See the previous section "2.1 Trace function" for the setting methods.
3
Select the item (data) to perform teaching.
4
Move the teaching unit to the target position.
Stay out of the axis movement range and then move the teaching unit to the target position using the
axis move keys.

If the "Outer Level" and "Inner Level" are OFF or set to "0", increase these lighting levels to about "+4" and
check that the target image is clearly displayed on the vision monitor. The "Coaxial Level" should be set
to "0" in this case.

TIP
The mark lights include the "Outer Level", "Inner Level", and "Coaxial Level". The “Outer Level” and “Coaxial Level” are
used when viewing thick land patterns with a flat surface. Set the lighting levels to an optimum value between "-1"
and "+5" while viewing the image on the vision monitor so that the land patterns are clearly seen.

Press the [Teach] button to perform teaching input.
There are two ways to perform teaching input: "one-point input" and "multi-point input".
1. One-point input
Check that the target position is aligned with the center of the vision monitor, and then press the
[Teach] button. The teaching data is input to the data item (XY coordinates) you selected in step 3.

2. Multi-point input
There are two ways to perform multi-point input.
Input method 1:
First move the teaching unit to the first teaching point (1) and press the [Set Point] button. Next
move the teaching unit to the second teaching point (2) and press the [Teach] button. The center
coordinates (XY) of the two points are input to the data item (XY coordinates) you selected in step 3.
The number of teaching points (2 in this case) is shown in the "Count" box.
