8.2.6 Setting and Operation of Three-Axis Spiral Interpolation
In the following example, an arc is drawn with the 1st axis (X-axis) and 2nd axis (Y-axis), and
a 3-axis spiral interpolation control is performed with 3rd axis (Z-axis) movement.
20000 pulses

Remarks
Axis numbers are put in (L) and (m).
For the auxiliary points, specify the
coordinate (0, 10000) to be the center
of an arc.
Axis numbers are put in (n).
Specify the movement amount of 3rd
axis (Z-axis).
