In "2-axis circular interpolation control" (" Da.2
right arc, ABS left arc, INC left arc), two motors are used to carry out position control in
an arc path centered around the center point specified by an arc address, 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 methods.
