INH Incremental auxiliary point-specified helical interpolation control
The linear interpolation to other linear axis is executed performing circular interpolation
from current stop position (start point) to specified circular relative end address (X
or linear axis end point relative address (Z
control is executed so that it may become a spiral course.
It goes around on the specified circle for the specified number of pitches, the circular
interpolation which had remainder specified is executed, and positioning to end
address is executed. The auxiliary point-specified circle specifies circular interpolation
method connected start point and end point at the seeing on the plane for which
performs circular interpolation.
Operation details for incremental auxiliary point-specified helical interpolation are
shown below.
