9.3.3.1 Control item: Vacuum ctrl.
This button turns ON/OFF the vacuum device of the selected head.
When the control item “Vacuum control” is selected, press the <ON> button, <OFF> button, or
<ON/OFF> button for control.
The displayed pressure is updated when the system finishes controlling the vacuum condition.
9.3.3.2 Control item: Z adjustment
This button controls the Z-axis coordinate of the selected head.
Use this button to pick up a component with a nozzle.
When the control item “Z adjustment” is selected, press he <Up> button, <Down> button, or
<Up/Down> button for control.
The displayed coordinate is updated when the head finishes moving completely.
9.3.3.3 Control item: Z fine adjust.
This button controls the Z-axis coordinate of the selected head.
Use this button to move the picked component to the laser measurement height.
When the control item “Z fine adjust” is selected, press the <Up> button, <Down> button, or
<Up/Down> button for control.
The displayed coordinate is updated when the head finishes moving completely.
9.3.3.4 Control item: Meas. (ONCE)
This button measures the head with laser (ONCE).
“ONCE” is the function for obtaining the information on the shadow shot with the sensor at the
present. The measurement result is displayed in the “Status” table.
When the control item “Meas. (ONCE)” is elected, press the <Exec> button for control. When
you select <LA> button, the head is moved to the end (bottom surface of component when a
component is picked up) of this head.
The measurement result displayed in the “Status” table is updated when the system finishes
measuring.
Select the window type to be used during measurement with the corresponding push button
displayed on the right bottom corner of the screen.
When you select other than the control item “Meas. (ONCE)” or “Meas. (SWEEP),” setting is
disabled.
a) Multi
This button sets an area in which two or more heads can measure components at the same
time as the window size.
(Center of the rotation of the nozzle attached on the specified head ±5.5mm)
When you plan to measure a component whose size exceeds this window size, select the
<Single> button.
b) Single
This button sets an area in which the maximum size component can be measured with laser
as the window size.
When you select this button, the system uses the measurement areas (windows) of other
heads also.
Therefore, if another head is moved down to the laser height, the system may fail to
measure a component.
Before measurement, check to see if any other head is not moved down to the laser
measurement height.

9.3.3.5 Control item: Meas. (SWEEP)
This control item measures the head with laser (SWEEP).
The SWEEP function rotates a substance to be measured in the detection area to detect a
component pick-up error, angle error and size. The laser unit analyzes the obtained data based
on the component shape specified in the “Compo shape” combo box to calculate the
measurement results. The measurement results are displayed in the “Status” area.
When the control item “Meas. (SWEEP)” is selected, press the <Exec> button for control. When
you select <LA> button, the head is moved to the end (bottom surface of the component when a
component is picked up) of this head.
The status displayed in the “Measurement result” area is updated when the system finishes
measuring.
For the window type at measurement, refer to “9.3.3.4 Control item: Meas. (ONCE).
9.3.3.6 Control item: String art
This button displays the string art (outline of a component) based on data obtained with the
SWEEP function.
When the control item “String art” is elected, press the <Exec> button for control.
For an example of string art based on the laser height, refer to the table shown on the next page.

String art and the laser height Description
This indicates the appropriate laser height. The laser sensor
obtained the shape of a component correctly. When the laser
sensor obtains the component shape, it returns the SWEEP
recognition result to the system.
If a component is not located at a position that is irradiated with
laser, the system does not obtain any edge data. Therefore,
any string art is not drawn, and the screen becomes black. In
this case, the laser sensor fails to perform SWEEP, and returns
a no-component error to the system.
If the laser height is almost the same as the height of the
bottom side of a component, the component does not shield
laser sufficiently and the sensor does not obtain the edge data
at several positions. Therefore, the string art shape becomes
inappropriate, and the laser sensor fails to perform SWEEP
and returns a recognition error to the system.
If the laser height is almost the same as the height of the
boundary between the top side of a component and the nozzle,
the component does not shield laser sufficiently in the same
way as the above. Therefore, the laser sensor fails to
perform SWEEP.
If the laser height is the same as not the height of a component
but that of the nozzle tip, the string art shows the shape of the
nozzle tip.
9.3.3.7 Control item: Image display
This button displays the image data sensed with the laser sensor for the selected head.
When the control item “Image display” is selected, press the <Exec> button for control.
