(2) Circular interpolation control
(Note-1)
There are two types of circular interpolation controls: circular interpolation with a
specified sub point and circular interpolation with the specified center point.
(a) Circular interpolation with a specified sub point
Circular interpolation is performed using the specified endpoint address and
sub point (passing point) address.
Two methods are available: absolute system and increment system.

REMARK
(Note-1): The interpolation speed during circular interpolation control may only be
set to "composite speed" for the interpolation speed designation method of
detailed parameter 1. (Refer to Section 5.2.3 information about setting
"[Pr.20] Interpolation speed designation method" of the detailed parameter
1.)
