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.
Fig. 5.4
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.

BEAM B X (Horizontal), Y (Vertical), ROTATION
The set offset data is used to adjust the positional and angular
deviations based on the design dimensions representing the
beam B driving X/Y coordinates (BeamB-X/Y: Origin B0)
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.

BEAM A/BEAM B HEAD #1/HEAD #2 ROTATION
This offset data (offset data for the origin positions of the head
rotational axis) is used to adjust the directions of the nozzle
clamp levers when the nozzles must be rotated for replace-
ment.
When the head rotational axis is zeroed and the nozzle clamp
levers face the directions shown in the figure below, a plus
parameter must be entered as the offset data.
When the rotational axis is zeroed, the nozzle clamp levers are
designed to face the “12 o’clock” and “6 o’clock” directions.
