Figure 7.3.1.1
2. Press the CAMERA key on the HOD to start teaching.
The camera moves to the X- and Y-coordinates of the mark, and the selected
mark appears on the monitor. If the mark does not appear on the monitor, check
if the entered coordinates are correct.
If you do not use a camera as a teaching device, an error sound beeps, and the
machine cannot perform teaching recognition.

3. Use the +Y and/or –Y key of the HOD to select which direction the recognized
image data is to be rotated: positive or negative. After selecting the rotating
direction, press the ENTER key.
Note: The machine detects a white part as a mark. Whether the mark is
recognized as white or black with respect to the board color depends on
the contrast between the mark and the board, and on the light level for
the camera’s field of view. Normally, the mark is recognized as white. If,
however, there are lands, patterns, or silk printings around the field of
view of camera, the mark may be recognized as black with respect to the
board color. In this case, normal correction is impossible. Reverse the
black and white by pressing the +Y or -Y key on the HOD so that the
mark appears as white. If a mark is recognized as black against the
board, press the +Y or -Y key to reverse the black and white so that the
mark can be recognized as white.
4. Adjust the scale frame.
Set the top, left, bottom and right sides of the scale frame with the direction key
(+Y, -Y, +X and/or –X) to adjust the size of the scale frame
The FAST key changes the moving distance of the scale frame.
The camera picture and a rectangle frame appear.
Set the top and left scale frames first. Adjust them
so that they match with the top and left of the mark.
When adjustment is complete, press the ENTER
key.
In the same manner as above, set the bottom and
right scale frames.
When adjustment is complete, press the ENTER
key.

5. Adjust the noise cut level.
Use the +Y and/or –Y key of the HOD to adjust the noise cut level around a
mark so that the mark can be viewed clearly, and the noise around the mark
can be reduced as much as possible. After finishing adjustment of the
noise cut level, press the ENTER key to confirm it.
6. Selecting a mark
The machine automatically judges and displays a mark. If the result has an
error, use the +Y and/or – Y key of the HOD to select a correct mark. After
selecting a correct mark, press the ENTER key to confirm the mark.
7. Adjusting the mark detecting range.
Use the direction key (+Y, -Y, +X and/or –X) to adjust the scale frame.
After adjustment of the scale frame, press the ENTER key to confirm the
frame.
Note: When you press the VAC ON/OFF key of the HOD, the machine
displays the previous setting screen.
