1 PRODUCT OUTLINE
(2) Circular interpolation control
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.
(b) Circular interpolation with the specified center point
Circular interpolation is performed using the specified endpoint address and
center point address.
Two methods are available: absolute system and increment system.
Also, the direction of movement can be selected from clockwise or
counterclockwise.
REMARK
(Note): The interpolation speed during circular interpolation control may only be set
to "synthesized speed" for the interpolation speed of the detailed parameter
1. (Refer to the Section 5.2.3 information about setting "
speed designation method" of the detailed parameter 1.)
