3 MAJOR POSITIONING CONTROL
3.2 Positioning Data Setting
Speed of the helical interpolation control
The circular interpolation control (Reference axis
Composite speed of the circular interpolation axis) is the target of the
command speed of the 3-axis helical interpolation control.
When 0: Composite speed is set in [Pr.20] Interpolation speed specification method, the command speed of
ABS3/INC3 is the composite speed of the three axes (x axis
y axis
z axis). The command speed of the 3-
axis helical interpolation control is the composite speed of the circular interpolation axis (x axis
y axis). When
the continuous path control is performed using ABS3/INC3 and the 3-axis helical interpolation control, the
movement speed of the workpiece may change at the positioning data switching; therefore, adjust the
command speed not to shake the workpiece.
Rotation angle of circular interpolation axis (x axis
y axis)
The rotation angle of the circular interpolation axis in the 3-axis helical interpolation control is as follows.
The setting of the true circle is available only when Start point = End point is set for the 3-axis helical interpolation (ABS/INC,
center point).

A linear interpolation axis tracks
the movement of circular
interpolation control.
The command speed of this control
is same as the speed of circular
