9 MAJOR POSITIONING CONTROL
9.1.6 Interpolation control
Meaning of interpolation control
In "2-axis linear interpolation control", "3-axis linear interpolation control", "4-axis
linear interpolation control", "2-axis fixed-feed control", "3-axis fixed-feed control",
"4-axis fixed-feed control", "2-axis speed control", "3-axis speed control", "4-axis
speed control", "2-axis circular interpolation control", and "3-axis helical
interpolation control", control is carried out so that a specified path is drawn using
a motor set in two to four axis directions.
This kind of control is called "interpolation control".
In interpolation control, the axis in which the control system is set is defined as the
"reference axis", and the other axis is defined as the "interpolation axis".
The QD75 controls the "reference axis" following the positioning data set in the
"reference axis", and controls the "interpolation axis" corresponding to the
reference axis control so that a linear or arc path is drawn.
The following table shows the reference axis and interpolation axis combinations.

The available axis combinations in the 3-axis helical interpolation control are the
same as the ones in the "3-axis linear interpolation control", "3-axis fixed-feed
control", and "3-axis speed control". However, the circular interpolation axis can be
specified with " Da.5 Axis to be interpolated" of the reference axis.
The following table lists the combinations of the reference axis, circular
interpolation axis, and linear interpolation axis for the 3-axis helical interpolation
control.

automatically assigned.
