7.2 Teaching Coordinates
7.2.1 Basic operating procedure
Coordinates teaching is generally done by the following procedure.
1. Move the cursor to the desired data position.
For X- and Y-axes, the coordinates of both axes can be taught.
While, Z-axis must be individually taught.
Figure 7.2.1.1
2. Using the HOD device keys, select the device to be taught.
If an illegal device is selected, an alarm beeps, prompting the operator to
reselect the device.
If coordinates have previously been entered, the selected device moves to that
coordinate position.
If not, the device does not move.
If the head is selected and a different nozzle is installed other than that used in
teaching, the nozzle is replaced.
In this case, the following information is shown on the screen.
– Selected device name
– X/Y coordinates of the selected device
– Z coordinate of the selected device
– θ -axis of the selected device
– Vacuum value of the selected device
The LED of each TEACH IN key (XY, Z) on the HOD lights up when
pressed, indicating what to teach.

3. Using the axis drive keys on the HOD (XY, Z), move the selected device.
As the device is moved, the numerals (coordinate values, etc.) shown on the
screen change.
An alarm beeps when the device reaches its motion limit, warning that the device
cannot be moved further.
The FAST key on the HOD may be used to change the motion speed of the
X-and Y-axes. The speed of the Z -axis cannot be changed.
4. When the device reaches the desired position, press the ENTER key on the
HOD to store obtained data (the coordinates of this point) into the machine
memory.
This completes the coordinates teaching procedure.
<Supplementary explanation for teaching speed>
1) Teaching speed selection
Pressing the FAST key on the HOD lights up the LED, and the motion speed
of the X-, and Y-axes changes from low to medium. To change the motion
speed back to low, press the FAST key a second time. The LED goes out
and the speed changes to low.
2) Step-by-step movement and continuous movement
Holding down an arrow key on the HOD continues the motion, and releasing
the key stops the motion. For step-by-step motion, do not hold down the key
but press it repeatedly.

7.2.2 Teaching X/Y-axis
The X and Y axes can be taught by using each nozzle the head the bad mark sensor,
or the camera. The operator can select the device according to his/her need.
Note, however, that some device may not be selected depending on the teaching
conditions.
The following explains the teaching procedure used for each of the three different
methods.
(1) Teaching with a nozzle
When you perform teaching operation with a nozzle, an operator has to select a
head as the first teaching device.
(2) Teaching with a bad mark sensor
When you perform teaching operation with a bad mark sensor, an operator has
to select a bad mark sensor as the first teaching device.
When you use a bad mark sensor, you can select the number of input points with
the POINT SEL key.
To enter two points, after selecting a teaching device, move the device and press
the ENTER key of the HOD for two points (move the device, press the ENTER
key, move the device, and press the ENTER key).
(3) Teaching by the camera
For teaching by the camera, select the device which is to be taught with the
camera first.
To perform teaching operation with a camera, you can select a teaching point
with two methods: entering two points or entering a point with a box window
(use the POINT SEL key to select which method is to be used).
You have to enter data corresponding to a teaching point respectively when you
use a camera as the teaching device.
After selecting a camera as the teaching device, move the teaching device and
press the ENTER key of the HOD by the number of input points: that is twice
(move the device, press the ENTER key, move the device, and press the ENTER
key).
When you use a camera as the teaching device, obtain the coordinate of each
point by the center (cross point) of the crosshair cursor.
Normally, use the crosshair cursor for point-by-point teaching, and use the axis
drive key for X- and Y-axes to move the crosshair cursor.
To obtain coordinates with the box window, first select WINDOW with the POINT
SEL key, and then press the SEL ENB key.
The cursor on the screen then changes from the crosshair to window.
