6.2 PCB origin
The reference point for the XY coordinates on a PCB is called the PCB
origin. The PCB origin is specified by the “PCB Origin” parameter in the
PCB Information.
The PCB origin must always be set since the PCB mark positions, compo-
nent mounting positions and the block repeat positions (refer to Chapter 6)
are specified by their coordinates relative to the PCB origin.

6.2.1 Normal PCB origin position setting
On standard machines with the front conveyor rail fixed, the center of the
fixed locate pin is specified as X=0.00, Y=0.00, which is 5mm (X and Y)
away from the forward corner of the PCB on the front conveyor rail side.
The PCB origin is normally set to the same position as the center of the
fixed locate pin.
In this case, enter “0.00” in the “X/X1” and “Y/Y1” columns of the PCB
Origin parameter on the PCB Info. screen.
