9.1.3 Operating the PAM Functions
When the PAM commands screen displays, the following commands are available,
[PAM Equip], [PAM Measure] and [Panel Loader].
PAM command screen.
9.1.3.1 Entering and Exiting PAM Mode
The PAM mode is enabled when you select [PAM Measure] at the [Maintenance]
command screen. Return to the [Maintenance] screen by pressing [Close].
9.1.3.2 Placing the PAM Parts
The [PAM Equip] command is used to place the PAM parts so the accuracy of placement
can be measured. Select this command and start automatic operation to carry out
placement.
The following procedural restrictions must be observed when carrying out PAM
placement.
1. The first placement sequence must be carried out using head A.
2. The operator must set the recovery mode to Error Pass before starting
PAM placement.
Any parts causing a parts out, pick-up miss or inspection error will be
skipped (i.e., not placed).
3. The loading and unloading of panels is carried out by the operator using
the loader commands.
4. If an emergency stop occurs during the placement of parts, placement
starts again from the first sequence (when operation is restarted). Use
the loader commands to unload the current panel before restarting
operation.

9.1.3.3 Measuring the Accuracy of Placement
The [PAM Measure] command is used to measure the accuracy of placement, when the
placement of PAM parts is complete. The loader commands must be used to load and
unloaded the panels. Ensure measurement is carried out with the XY-table at its lower
limit.
9.1.3.4 Loading and Unloading Panels
The [Panel Loader] command is used to load and unload panels.
9.1.3.5 Carrying Out PAM at the Machine
The following procedures are for the measurement of placement accuracy, and updating
of the machine data.
Carrying Out PAM With the Cam Speed at 80% and Updating
the Machine Data
1. From the main screen, press [Maintenance] - [PAM Measure], and then
set the cam speed to 80%.
2. Select [PAM Equip] and START to carry out the placement of the PAM
parts.
3. Press [PAM Measure] and START to carry out measurement of the
placement accuracy.
4. Press [Renewal] to update the machine data.
Carrying Out PAM With the Cam Speed at 100% and Updating
the Machine Data
1. From the main screen, press [Maintenance] - [PAM Measure], and then
set the cam speed to 80%.
2. Select [PAM Equip] and START to carry out the placement of the PAM
parts.
3. Press [PAM Measure] and START to carry out measurement of the
placement accuracy.
4. Press [Renewal] to update the machine data.
Note: Make sure that the program selected is suitable for production at a cam speed of 100%.

9.1.4 Measuring the PAM Placement
Press [Maintenance] - [PAM Measure] - [PAM Measure] - [100%/80%] - [OK] - [PAM
Measure] to display the following screen and enable the START button. Press START to
begin the measurement. The vision monitor displays during the measurement.
9.1.4.1 Move Mode
Measurement can be carried out in Continue or Step mode.
9.1.4.2 Result
The deviation results for the measurement of PAM part placement are given for each
sequence as 3s, 6s, Max., Min., Cp and Cpk.
9.1.4.3 Indicate Distribution
The distribution diagrams of the measurement results display.
9.1.4.4 File Save
The results are saved as a file.
The results files are saved at "\Fuji\User\Data" in order with the names "Pam001.Dat" to
"Pam005.Dat". The format of the files is described later in this document.
9.1.4.5 Renewal
The results are used to update the machine data placement offset items.
9.1.4.6 Editing Offset Tolerances
The offset tolerances can be edited.
