7.1.2 Attitude Control B (Offset Nozzle)
Overview
The offset mechanism consists of the α (4th) axis that rotates on the Z
axis and the β (5th) rotation axis associated with the α axis. In this
structure, the nozzle head is positioned at the point of intersection of
the center lines of α-axis rotation and β-axis rotation, and the center
lines of α-axis rotation and the nozzle do not intersect.
Reference positions
The reference attitudes of the α and β axes are indicated by their
zero-degree positions and rotation directions shown in the above
figure.
Reference position of the α axis
When the α axis is viewed from the +Z direction, the position where
the arm faces in the +Y direction is 0°. When +90° rotation from that
position is commanded, the α axis rotates counterclockwise and
matches the -X direction.
