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.

Example of Jig PCB Usage
The gure below shows that the upper surface of a PCB is lower than the
PCB upper surface reference.
If "PCB Upper Surface Reference + a" is set as an offset value at this time,
components can be placed correctly on the PCB.
