2-Axis Circular Interpolation Control With Center Point Designation - Mitsubishi Electric MELSEC-L LD75P User Manual

9.2.11
2-axis circular interpolation control with center point
designation
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  Page 359, Section 9.1.6 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.
