3.3.6 Helical Interpolation Execution
Before performing helical interpolation, set the position data that is set in 3.3.4 again, and then helical interpolation will be
performed by CW helical interpolation driving command (69h) or CCW helical interpolation driving command (6Ah). Write CW
helical interpolation driving command (69h) in WR0 register when to rotate the circular arc on the XY plane in the CW direction,
and write CCW helical interpolation driving command (6Ah) in WR0 register when to rotate it in the CCW direction, and then
helical interpolation will be performed.

Before starting helical interpolation, all the necessary data must be set. For more details of setting items, see chapter from 3.3.1 to
3.3.5.
3.3.7 Current Helical Rotation Number Reading
During helical interpolation, the user can read the current rotation number by current helical rotation number reading command
(3Ah). The helical rotation number is counted up at the timing when it returns to the start point after one rotation of circular
interpolation.
