<<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.

Discard point
This parameter specifies the discard position where each head discards a
component and air blow settings for preventing nozzle clogging.

<<<APPLICATION>>> 3/MAINTE/M
<<MODE>> 2/MCH_DATA
Type Specifies whether to perform air blow to prevent nozzle
clogging with dust or solder. See “Wait point” for more
details.
X, Y Position where Head 1 discards a component. A typical
discard point is entered at the factory prior to shipping to
match the position of the dump box. Do not change this
setting.
Z Height of the nozzles when dumping a component. A typical
height is entered at the factory prior to shipping. This is
usually “0.000” because it is not necessary to lower the
nozzles when dumping a component.
Feeder Indicates the time duration for which air blow turns on to
discard or mount a component (in milliseconds). This is valid
only for machines with an air blow unit and is typically set to
20 to 100ms.
Reference
On standard YV180X, a component dump box is attached with the screws to the outside of
the fixed conveyor rail (A table) or movable conveyor rail (B table). This position cannot
be changed.

PCB Height
This parameter indicates the height of the PCB in the component mounting
position and also specifies whether to check a nozzle after mounting or
discarding a component.

<<<APPLICATION>>> 3/MAINTE/M
<<MODE>> 2/MCH_DATA
Type Specifies whether to check the nozzles during automatic
operation.
NO USE Does not make any check.
DUMPChecks a nozzle after it dumps a component.
MOUNT Checks a nozzle after it mounts a component.
R Height of the pallet of a fixed tray feeder. (This setting is
invalid for the YV180X.)
Z Height of the head assembly positioned to mount compo-
nents on a PCB.
Feeder Relative up/down speed (%) of the push-up plate. This speed
is preset to 100 (%) prior to shipping. (This setting is invalid
since the push-up plate of the YV180X moves upwards by air
pressure.)
To set the PCB height (Z coordinate), follow the steps below. Before
beginning the work, check that Type 72 nozzles are attached to all heads.
Since the height of the fixed conveyor rail surface is basically the same as
the PCB height, set it as the PCB height here.
1 Select the XY axis to move the head assembly and conveyor
table.
Select <3/4/B1 SELECT SERVO MOTOR> - ”A-table XY” (or “B-table XY)
and press the [ENTER] key.
2 Move the head assembly to above the fixed conveyor rail.
Using the YPU joystick, move the head assembly so that all heads are
positioned directly above the fixed conveyor rail.
