9 MAJOR POSITIONING CONTROL
POINT
When "0: Composite speed" is set in " Pr.20 Interpolation speed designation
method", the command speed of ABS3/INC3 is the same as the composite speed
of the 3 axes (x axis - y axis - z axis). The command speed of 3-axis helical
interpolation control is the same as the composite speed of the circular interpolation
axis (x axis - y axis). When continuous path control is carried out in ABS3/INC3 and
3-axis helical interpolation control, adjust the command speed to prevent the
workpiece from moving unsteadily because the workpiece movement speed may
change when positioning data is switched.
Rotation angle of the circular interpolation axis (X axis - Y axis)
The following shows the rotation angle of the circular interpolation axis in 3-axis
helical interpolation control.

A true circle can be set only when the start point equals to the end point in 3-axis
helical interpolation (ABS/INC, center point).
POINT
When "degree" is set for the unit setting in the absolute system, the positioning
range is 0 to 359.99999°. When the axis rotates 360° or more in circular
interpolation control (x axis - y axis), the tangential/normal control cannot be carried
out because a degree of 360° or more cannot be set in linear control (z axis:
degree). To carry out tangential/normal control in which the axis rotates 360° or
more, use 3-axis helical interpolation control (INC).
