BEAM A X (Horizontal), Y (Vertical), and ROTATION
The set offset data is used to adjust the positional and angular
deviations based on the design dimensions representing the
beam A driving X/Y coordinates (BeamA-X/Y: Origin A0)
viewed from the P.C.B. positioning X/Y coordinates (PL-XY:
Origin P0). The values based on the PL-X and PL-Y coordi-
nates must be entered in the data boxes.
• Design Values
X: -94.000 mm, Y: +496.000 mm
Origin A0 is the scanning coordinate center of the P.E.C.
camera installed on Beam A when Beam-A X/Y axis are
located at their origins.
This offset data is automatically calculated through teach-
ing operation which is performed, using a jig P.C.B.

When the beam A driving X/Y coordinates (actual values) are
those as shown above, the offset parameters representing the
X (horizontal) and Y (vertical) values must be provided with
minus (-) signs and the offset parameter representing the rota-
tion (angle) with a plus (+) sign.
BEAM A/BEAM B HEAD #1/HEAD #2, UP/DOWN
This offset data (offset data for the origin positions of the head
up/down axis) is used to adjust the distance between the P.C.B.
positioning reference point on the upper surface of a P.C.B.
and the origins of the head up/down axis.
Plus parameters entered in these data boxes increase the down-
ward movement of the head.
