Edge clamps
When edge clamps are used to secure a PCB on the conveyor instead of
using the locate pins, the PCB position may shift slightly relative to the
position determined by the locate pins. If a shift (in millimeters) is found,
subtract it from the locate pin coordinates and enter this coordinate data for
“Edge clamp”. Usually, enter here the same coordinate data as that for
“Locate pin”.

X, Y Position where the head assembly stands by during PCB
transfer. A typical standby position is entered at the factory.
(The Y position is not used for the YV180X.)
Z Height of the head assembly during PCB transfer. This should
be set to “0.000”. Do not change this setting.
R Rotary angle of each head during PCB transfer. This should be
set to “0.000”. Do not change this setting.

Machine adjust mode
When you want to change the X position of the Wait point, use the teaching
procedure as described below.
1 Open the Position screen.
Select <3/3/B1 ADJUST TARGET> −“Position” and press the [ENTER] key.
2 Press the [F10] key and specify teaching conditions.
Select “Head 1” for the teaching unit and a slow speed (e.g. SPEED=20 to
40), and press the [ENTER] key.

3 Line up the cursor with “X” in the “Wait point” row.
4 Move the head assembly to the desired wait point.
Manipulating the YPU joystick, move the head assembly to the desired
position.
5 Perform teaching for the wait point.
Press the [F10] key twice to perform teaching for the X coordinate of the
wait point.
6 Save the settings.
Press the [ESC] key, then select <B2 SAVE DATA> or <B0 SAVE & QUIT>
and press the [ENTER] key. (To quit without saving, select <B3 RECOVER
ADJUST> or <B7 QUIT> and press the [ENTER] key.)

<<Nozzle clog prevention air blow>>
To prevent the nozzles from being clogged with dust and solder, this
function is used to blow away such foreign matter in the nozzles when the
head assembly is at the “wait point” or “discard point”. This function and
the air blow time can be specified in the Type and Feeder columns of the
Wait point and Discard point parameters.

Caution
When this air blow is performed at the “wait point”, be sure to set the “wait point” at a
position which is not above the PCB or feeder.
The setting in the Feeder column of the Discard point is shared with the air blow timer
for separating a component from the nozzle just after the component has been mounted
on the PCB. If this setting is too large, the component may bounce off the PCB at the
instant it is mounted.
