Error compensation of the circular interpolation axis
In the 3-axis helical interpolation control with center point designation, as well as the 2-axis circular interpolation control,
"[Pr.41] Allowable circular interpolation error width" is enabled. When a circular interpolation error occurs, the path of the
circular interpolation control (X axisY axis) becomes spiral as shown below.
Rotation direction when the linear interpolation axis (Z axis) is set in degrees
When "degree" is set to "[Pr.1] Unit setting" for the linear interpolation axis, the rotation direction is determined depending on
the axis control data in "[Cd.40] ABS direction in degrees" of the reference axis. To set a rotation direction for each positioning
data, set "[Da.28] ABS direction in degrees" of each positioning data.
