12.2 Teaching
The teaching function is used to teach the machine a position such as XY
coordinates. There are two teaching methods: “point teaching” and “vision
cursor teaching”.
12.2.1 Point teaching
Point teaching is further divided into “single point input” and “multi-point
input”. The “single point input” allows the teaching data to be directly
entered, while the “multi-point input” gives the center coordinates in the
multiple positions which are specified. The steps below explain the teach-
ing procedure in the DATA Manager.
1 Set teaching conditions.
As with the trace function, use the <2/1/B0 TEACH, TRACE CONDITION>
command. (Refer to Step 1 in the previous section “12.1 Trace”.)
2 Secure a PCB on the conveyor.
Use the <2/1/B7 CONVEYOR UNITS> utility to secure the PCB on the
conveyor.
3 Move the cursor to the item for which you want to perform
teaching.
On the Mount Info. screen, for example, move the cursor to the line of the
data for which you want to perform teaching.
4 Move the teaching unit to the target position.
Check safety and stay out of the axis movement range, then manipulate
the YPU joystick to move the teaching unit to the target position.
5 Press the [F10] key to perform teaching as follows.
For “single point input”:
Press the [F10] key twice.
When you first press the [F10] key, a short beep sounds, then press the
[F10] key again to enter the teaching data.
For “multi-point input”:
1. At the first teaching point, press the [F10] key twice while holding
down the [Shift] key.
2. At the subsequent teaching points, press the [F10] key once per point
while holding down the [Shift] key.
3. At the last point, press the [F10] key only.
The center coordinates in the area specified by multiple teaching points
are now entered for the data at which the cursor is aligned.
4. If you want to cancel the teaching data, select <2/1/D9 ABORT PCB
DATA> and press the [ENTER] key.
Reference
Teaching can also be performed by executing the <2/1/B9 TEACHING> command. For
manipulating the YPU joystick, refer to “3. Manual operation” in Chapter 3.

12.2.2 Vision cursor teaching
Vision cursor teaching allows you to obtain position data which is more
accurate than normal point teaching. A teaching window with any desired
size is displayed on the vision monitor and its center position obtained. The
target mark or pattern must be displayed on the vision monitor.
1 Clamp the PCB on the conveyor and set teaching condi-
tions.
As with point teaching, clamp the PCB on the conveyor, and set teaching
conditions by executing the <2/1/B0 TEACH, TRACE CONDITION>
command. In this case, the teaching unit must be set to “Camera”.
2 Move the camera to the target position.
Check safety and stay out of the axis movement range, then manipulate
the YPU joystick to move the camera to above the target position.
3 Press the [Ctrl] + [F10] keys.
A teaching window appears on the vision monitor as shown below.

4 Adjust the teaching window position and size to match the
pattern or mark size.
At the top left of the vision monitor, the coordinates of two diagonal
corners of the window are displayed. Adjust the window position and size
to match the pattern or mark size as follows:
1. When an asterisk (*) is prefixed to each of the two coordinates as
shown above, pressing the arrow keys allows the window to move in
the direction indicated by arrow.
Use the arrow keys to move the window so that its upper left or lower
right corner is properly positioned for the target land patterns or mark.

2. When you press the [TAB] key, the asterisk (*) of the right-hand
coordinates disappears as shown in the figure below. This state allows
you to enlarge or reduce the window size by changing the position of
the upper left corner with the arrow keys (the lower right corner is
stationary in this case). Adjust the window size to match the pattern or
mark size.

3. When you want to adjust the window size by changing the position of
the lower right corner, press the [TAB] key again. The asterisk (*) of the
left-hand coordinate pair disappears but an asterisk reappears at the
right-hand coordinates, as shown in the figure below. This state allows
you to enlarge or reduce the window size by changing the position of
the lower right corner with the arrow keys (the upper left corner is
stationary in this case).
