2.2 Notes on Using PAM
In order to use PAM, the machine’s control card ROM must be replaced with the PAM
card ROM. Production operations are not possible while the PAM card ROM is installed
in the machine. To restore the machine’s production capabilities, the machine’s control
card ROM must be re-installed.
Moreover, the CP-6 PAM does not support the following commands and functions.
Commands
• Block skip
• Recovery
• Pass Mode
• Turnover Operation
• Nozzle skip
Functions
• Nozzle skip following a nozzle-centering alarm
• Statistical nozzle skip
• HELPS

2.3 Procedure Overview
Part Data and Nozzle Assignment Table
Prepare the part data and Nozzle Assignment Table for PAM.
1. 6 types of part data must be created.
The 6 types of part data are based on the standard 3216R part data, with only the
nozzle size being specified (input item: Nozzle_size_CP6).
• Part Data
Nozzle
No.1_3216 1.1 mm Data for part pick-up with the No.1 nozzle
No.2_3216 1.2 mm Data for part pick-up with the No.2 nozzle
No.3_3216 1.3 mm Data for part pick-up with the No.3 nozzle
No.4_3216 1.4 mm Data for part pick-up with the No.4 nozzle
No.5_3216 1.5 mm Data for part pick-up with the No.5 nozzle
No.6_3216 1.6 mm Data for part pick-up with the No.6 nozzle
2. Create the Nozzle Assignment Table as shown below.

5 1.5 12 0.050 0
6 1.6 12 0.050 0
Notes: Regarding the input items at the part data and Nozzle Assignment Table
1. Although the 1.3 mm size nozzle is used for all the PAM nozzles (Nos.1 to 6),
different sizes (in 0.1 mm increments) must be entered as shown above in the “Part
Data” and “Nozzle Assignment Table” in order to differentiate between the 6 nozzles
(this prevents nozzle changes during PAM placement operations). By entering the
nozzle sizes in 0.1 mm increments, parts will only be picked up by the nozzle number
specified in the program.
Within the vision processing system for PAM, however, all the nozzle sizes are
processed as 1.3 mm.
2. If there are not enough 1.3 mm nozzles, perform measurement by placing all 20 1.3
mm nozzles on each head in order from No.1 to No.6 nozzle positions.
PAM Measurement
The PAM measurement occurs using the 20 No.1 nozzles at the 20 heads. If an accuracy
measurement fails, it is repeated until a result is obtained.
Note: The No.2 to No.6 nozzles are not used in the accuracy measurement.
No.2 to No.6 Nozzle Measurement
The No. 2 to No. 6 nozzle measurements are performed in the same manner as step 2.

2.4 Simplified Measurement Technique
The CP-6 series is designed so that the nozzle shafts are aligned in a straight line relative
to the head shafts. When a nozzle is changed, there is almost no variation between the
nozzle centers. This means that a PAM measurement can be performed for only 1 of the
6 nozzles, with the results for that nozzle applying to the other nozzles. The accuracy
can therefore be checked simply by repeating the nozzle center measurement.
1. Use the standard 3216R part data as the measurement part data.
2. Assuming that the following nozzle combination is used, a 1.3 mm nozzle is
mounted at No.3.
• No.1 nozzle 0.7 mm
• No.2 nozzle 1.0 mm
• No.3 nozzle 1.3 mm
• No.4 nozzle *.* mm
• No.5 nozzle *.* mm
• No.6 nozzle *.* mm
3. Create the Nozzle Assignment Table as shown below.
• Nozzle Assignment Table
Nozzle_No Nozzle_Size Back_light_size Bend_Limit Nozzle_type
1 0.0 00 0.000 0
2 0.0 00 0.000 0
3 1.3 12 0.050 0
4 0.0 00 0.000 0
5 0.0 00 0.000 0
6 0.0 00 0.000 0
4. Copy the No.3 measurement results to all the other nozzles.
5. Perform a nozzle center measurement.
6. Run PAM again to verify that an accuracy result is obtained.
