6 POSITIONING CONTROL
6.9 Helical Interpolation Control
The linear interpolation control with linear axis is executed simultaneously while the
circular interpolation specified with any 2 axes is executed, the specified number of
pitches rotates spirally and performs the locus control to command position.
