6.1.17 Helical interpolation control with auxiliary point designated
3-axis control by ABH (absolute method)
(1) Helical interpolation control is realized by linearly interpolating the linear axis while
executing circular interpolation from the current stop address (address before
positioning) based on the zero point, through the designated auxiliary point
address on the arc end point address and linear axis end point address.
