1.1.2 Nozzle Reflective Disk Diameter Data (Program)
The diameter of each nozzle’s reflective disk is input into program
data to facilitate production.
[Program] Machine_data
42. S_back_light_size: Input the diameter of the reflective disk
for the S nozzle in 1 mm increments.
Default is 12 mm.
43. M_back_light_size: Input the diameter of the reflective disk
for the M nozzle in 1 mm increments.
Default is 12 mm.
44. L_back_light_size: Input the diameter of the reflective disk
for the L nozzle in 1 mm increments.
Default is 25 mm.
1.1.3 Part Data Nozzle Diameters
There are two fields in Part Data which are used in the automatic
selection routine of the FCP IV-3. They appear under
Carrying_data, as follows.
[Part data] Carrying_data
17. Nozzle_size_max. :
19. Nozzle_size_CP4 :
Since each part has its own Part Data file, data input here is specific
to the part that the file describes. Nozzle_size_max. defines the
maximum diameter of the nozzle which can be used in placing the
part. This is referenced by the FCP IV-3 during automatic nozzle
selection.
Nozzle_size_CP4 defines the specific nozzle diameter when a
specific nozzle size should be used. In this case, the data in
Nozzle_size_max. is not used; the FCP IV-3 is forced to use the
specified nozzle diameter to place the part. Do not input
Nozzle_size_CP4 if automatic selection of the nozzle is desired.

1.1.4 Minimum Disk Diameter (Part Data)
This data item is where the minimum diameter of the reflective
disk is specified.
[Part Data] Carrying_data
16. Back_light_min: Input the smallest disk diameter to be
handled by vision processing in 1 mm
increments.
1.1.5 Automatic Selection Method
The nozzle actually used in placing a part is automatically selected
by the FCP IV-3 if no nozzle diameter has been specified in
Nozzle_size_CP4. The FCP IV-3 checks the maximum nozzle
diameter permitted in the Part Data file, then chooses the nozzle
defined Machine_data in the program that is closest to the
maximum size, but not greater than it. Furthermore a check is
made to determine whether the background disk of the nozzle will
allow the part to be vision processed.
For example, if data is specified as shown below, the maximum
nozzle permitted for part “RECT3216120” is 1.3 mm in diameter.
The closest nozzle diameter set in the program without exceeding it
is the M nozzle at 1.0 mm. Therefore, this nozzle would be chosen
to place this part.

FCP IV-3 Operation
Chapter 1 Automatic OperationPart 2
If each nozzle defined in the program is of a larger diameter than
that specified for Nozzle_size_max., an error occurs when the
program is transmitted.
In other words, if the value specified in Nozzle_size_max in Part
data is smaller than the S_nozzle_size in Machine_data, in the
program then there is no nozzle capable of placing the part and an
error will occur when the program is transmitted. In such a case,
the error code 1101109? is generated, where ? is a hexadecimal
value (A – F or 0 – 9).
A nozzle diameter must be input in the program for each size
nozzle. If a nozzle is undefined, the error code 11011325 is
generated when the program is transmitted.
