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.
