PCB origin offset
X (Horizontal), Y (Vertical) [mm]
Set the offset values to correct the difference between the placement
coordinate reference (N0) and the PCB origin (P0).
"Plus" or "Minus" can be set in both X and Y coordinates in the direction of
the correction.

Z (Angle) [deg]
Set the offset value for component placement angle.
The set value is added to the "Offset Z (deg)" of all components in the
placement data (P data).
To correct the angle of component placement counterclockwise, a parameter
must be entered with a plus (+) sign. A minus (-) sign must be afxed for
clockwise correction.

X-Direction and Y-Direction
"Same" or "Opposite" can be selected as the X and Y directions in the
placement reference coordinate system.
Same
: Select this when the direction of the coordinates is the same
as that of the machine coordinates.
Opposite
: Select this when the direction of the coordinates is opposite,
compared with the direction of the machine coordinates.

Z-Direction
Select one of the following options to determine the Z angular orientation of
the placement coordinate reference point.
Same
: Select this when the angular orientation is the same as that
of the machine coordinates.
Opposite
: Select this when the angular orientation is opposite,
compared with the direction of the machine coordinates.

PCB height offset [mm]
Set an offset value as a nozzle descending distance based on the upper
surface of the PCB in the component placement section. This offset value
applies to all components in the pattern program.
Normal Cases
Set "+0.000" (zero) in the text box.
The gure below shows that the upper surface of a PCB is maintained by
the PCB support pins at the PCB upper surface reference.
