*1
: It means that it need not be set. Whatever value it is, it dose not affect circular interpolation.
Remark
(1) Radius specified circular interpolation is executed on the basis of the items set on operating data of main axis
(command axis). When it is executed, only
「
Target position
」
among sub axis items can affect circular
interpolation. In other words, whatever value is set as, it does not affect the action and no errors arise. But,
coordinate setting of sub-axis control method means whether target position is absolute coordinate or
incremental coordinate. So in case of circular interpolation control by absolute coordinate method, set the
coordinate of sub-
axis as “Absolute” too.
(2) When setting the circular interpolating auxiliary point (radius) of main-axis, it must be bigger than the half of
the length between starting position and target position. When it is smaller than the half(R), if the value is higher
than 80% of R, circular interpolation which has middle point between starting position and goal position as center-
point is executed, and if the value is lower than 80% of R, error (error code:270) arises and circular interpolation
is not executed.
