Screen Display
If a fiducial mark is not read, * * * * displays in OFST in memory.
When all marks are read properly, Data Set command becomes invalid
to maintain accuracy.
If there are any fiducial marks which have not been read, Skip command
becomes invalid for the board. (Because of lack of data to calculate OFST
in memory.)

7.3.3 Description of Commands
Set data: Use this command to manually specify the fiducial mark
coordinates. Pressing this key changes the OFST in
memory value to the difference between the mark
sequence coordinates and the current position
coordinates. This key is not displayed on the screen
when all fiducial marks have been read properly.
When current position adjustment is needed, perform
inching and then press the Set Data key.
If the difference between mark sequence coordinates and
current position coordinates is bigger than the camera
F. O. V., the machine recognizes it as an input error and
the message Input error displays.
When data setting is complete, Set data displays on the
screen.
Press the Set Data key again to cancel the manual entry
mode. The Set data display disappears.
If the operator starts automatic operation after cancelling
manual entry, the machine will start to read the mark.

Chapter 7 Fiducial Mark Recovery CommandPart 2
Skip: Press this key to skip a fiducial mark and calculate the
correction value based on the OFST in memory value
previously read and currently displayed on the screen.
If this key is pressed for a mark which has not been read
yet, the machine recognizes it as an input error because of
a lack of data, and Invalid command will display on the
screen.
When this command is activated, Skip displays on the
screen, and the function key display for F2 changes to
Cancel. Press Cancel to cancel the skip command.
Start automatic operation with F2 set to Cancel, and the
machine will read the mark.
Bright: Press this key to change the gain or offset of the camera.
Speed: Press this key to change the inching speed for current
position adjustment.
Return: Press this key to end the Mark Editor and return to the
previous screen. The machine ends the image reading
operation and the cross-hair on the vision processing
monitor disappears.
The Skip or Set Data command settings are valid only for the board
currently on the table.
When the production of the board is complete, or the board is
unloaded, these commands will automatically be cancelled, and the
production of the next board begins with regular settings.
Note that the machine may try to read a mark specified to be
skipped again depending on conditions.
7.3.4 Cautions
When the Set Data or the Skip command is activated, placement
accuracy may not attain the accuracy Fuji guarantees.
Use these commands only when other recovery actions are invalid.
When it is clear that mark sequence coordinates or mark shape is
not proper, change the production program instead.
