XY-Angle [deg]
Set the offset value for the angle between the machine coordinates
system and the placement coordinates reference system.
To correct the angle of component placement counterclockwise, a
parameter must be entered with a plus (+) sign. A minus (-) sign must
be affi xed for clockwise correction.

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 Angular Orientation
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.
