[2] 2-axis circular interpolation control with center point designation
(INC circular right, INC circular left)
Operation chart
In the incremental system, 2-axis circular interpolation control with center point
designation, positioning is carried out from the current stop position (start point
address) to a position at the end of the movement amount set in "
Da.6
Positioning address/movement amount", in an arc path having as its center the
address (arc address) of the center point set in "
Da.7
Arc address".
