In "2-axis circular interpolation control" (" Da.2 Control system" = ABS circular right,
INC circular right, ABS circular left, INC circular left), two motors are used to carry out
position control in an arc path having an arc address as a center point, while carrying
out interpolation for the axis directions set in each axis.
(Refer to Section 9.1.6 "Interpolation control" for details on interpolation control.)
The following table shows the rotation directions, arc center angles that can be
controlled, and positioning paths for the different control systems.
