9.2.7 2-axis circular interpolation control with center point designation
In "2-axis circular interpolation control" (" Da.2 Control method" = ABS right arc, INC
right arc, ABS left arc, INC left arc), two motors are used to carry out position control in
an arc path having a designated 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 methods.
