To teach two points, follow the procedure described below.

① 2-point teaching

Enter points A and B. The coordinates of point C, which is the center

between points A and B, is then computed and taught.

② When teaching by the window cursor

Move around the top, left, bottom and right side of the window frame with the

direction key (+Y, -Y, +X and/or –X) to enter coordinates.

First, move to the top and left sides, and press the ENTER key.

Next, move to the bottom and right sides of the frame, and press the ENTER

key. The center of the box window is regarded as the taught coordinates.

When the ENTER key is pressed after moving to the bottom and right, the

camera moves so that the center of the window box is placed at the center

of the previous crosshair cursor. The window box is then changed to the

crosshair cursor.

7.2.3 Teaching Z-axis

For Z-axis teaching, the operator must first select the device with which Z-axis is to

be taught as described in the procedure given in 7.2.1 “Basic operating procedure”.

Only the head can be selected as the device. An error results with an alarm beep if

any other device is selected, and the operator must starts the operation from the

device selection.

This teaching is for height teaching. Lift down slowly the nozzle tip until it touches the

object for measurement, and measure the height. Never push the nozzle into the

object. After selection is made, the same method applies.

CAUTION

When you use the ↓-Z key to perform Z-axis teaching, the Z-axis

immediately moves down to the point 6 mm lower than the height you

set.

This may damage a nozzle, so do not perform Z-axis teaching around

the PWB transport rails (reference pin position or follower pin position)

or directly above a tall component.

7.2.4 Teaching vacuum value

Vacuum values are automatically set when component measurement is performed.

So, teaching is not necessary.

7.3 Teaching Recognition

7.3.1 Teaching of a Board Mark

The following describes the basic operating procedure for teaching recognition.

1. Move the cursor to the mark of the desired data position.

T o start teaching recognition, X- and Y-coordinates of the mark shall be entered

beforehand.

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.
