(3) Wrist figure
A wrist figure is defined by a set of the values of the 4th- and 5th-axis components.
The robot can take two different shoulder figures--Normal (NONFLIP) and Reversed
(FLIP). The NONFLIP figure refers to a figure of the robot whose 4th axis is turned
by 180 degrees without changing the wrist figure. (J1 to J6 denote Joint 1 to Joint 6.)

(4) 6th-axis figure
A 6th-axis figure is defined by the value of the 6th-axis component.
The robot can take two different 6th-axis figures--SINGLE and DOUBLE. If the 6th
axis rotates by -180°<θ
6180° in mechanical interface coordinates, the figure is
SINGLE; if it rotates by 180°<θ
6360° or -360°<θ6-180°, the figure is DOUBLE.
The robot takes quite different figures when θ
6 is 180° or 181°. Take special care
when changing any position data fort the 6th-axis figure. For example, supposing
that you want to change the 6th-axis figure at θ
6=181°, the robot will take the 6th-axis
figure at θ
6=-179° if you make no figure modification.
