1.3 Point teaching
Point teaching can be performed by "one-point input" or "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 that were specified.
1
Press the [Teach] button to open the Teach screen.
TIP
When you perform teaching on a board and the board is not yet clamped on the conveyor, a check dialog box
appears asking you to load a board. Follow the message on the screen to load the board on the conveyor.
When you perform teaching on a mask, clamp the mask on the printing table.

Check the [Point] tab is opened.
3
Set the speed and operation mode.
Use the [Up Arrow] button or enter the desired speed in the box set the axis movement speed during
teaching. Setting to a lower speed is recommended for safety.
When the [Step Mode] button is pressed, you can move the teaching unit in the inching mode (jog
mode).
4
Follow the message on the screen to load a board on the conveyor.
This step is skipped when a board has already been clamped on the conveyor.
After the board is clamped, the board fiducial mark will be automatically recognized with the vision
camera. (This mark recognition is skipped if not using the fiducial mark function.)
5
Select the data item for which you want to perform teaching.
Line up the cursor with the data line on the upper part of the Teach screen.
6
Move the teaching unit to the target position.
Check safety and stay out of the axis movement range, then use the arrow buttons to move the
teaching unit to the target position. Hold down the arrow button for a continuous movement. The
current XY coordinates are shown on the arrow buttons.

lighting levels. After adjusting, press the [Close] button to return to the Teach screen.
Light level adjustment
64604-L3-00
TIP
Optimum light levels depend on the materials of the board, mask frame and mark. Use the following method to find
optimum light levels.
1. Turn off all light units.
2. Turn on, one at a time, "Outer Light", "Inner Light", "Coaxial Light, "IR Outer Light" and "IR Inner Light" at the
maximum level, to see how clearly the mark can be seen.
3. Combine the light units that were effective, and adjust their light levels.
As a general guide for adjusting board mark lighting, try these suggestions.
• Flat surface marks reflecting light : "Coaxial Light" is effective.
• Flat surface marks made of copper oxide : "IR Inner Light" is effective.
• Marks with uneven surface diffusing light : "IR Outer Light" is effective.

Press the [Teach] button to perform teaching input.
There are two ways to perform teaching input: "one-point input" and "multi-point input".
l
One-point input
After checking that the center of the target point is aligned with the center of the vision monitor,
press the [Teach] button.
One-point input
Center position data is input. [Teach] button

TIP
When the [Click Move] button is turned on (pressed), clicking the mouse at the target point where you want to
perform teaching makes it easier to align the target point with the center of the vision monitor.

Multi-point input
The following steps explain the teaching method when the [Click Move] button is pressed. (If not using click movement,
use the [Axis movement] buttons to move the teaching unit to each target point.)
1. Click the mouse button at the first point.
The teaching unit moves to the first point and the first point is displayed at the center of the vision monitor.
2. Press the [Set Point] button.
3. Click the mouse button at the second point.
The teaching unit moves to the second point and the second point is displayed at the center of the vision monitor.
4. Press the [Set Point] button.
5. Click the mouse button at the third point.
The teaching unit moves to the third point and the third point is displayed at the center of the vision monitor.
6. Press the [Set Point] button.
7. Click the mouse button at the fourth point.
The teaching unit moves to the fourth point and the fourth point is displayed at the center of the vision monitor.
8. Press the [Teach] button.
The center position of the four points is input as the teaching position.
TIP
For two-point input, perform teaching at two points as shown below. The center coordinates of the two points are
input as the teaching position. The number of teaching points (2 in this case) is shown in the "Count" box. To cancel
the previous point, press the [Clear Point] button.
