Chapter 9 Major Positioning Control
Positioning data setting example
[When "4-axis linear interpolation control (INC linear 4)" is set in positioning data
No. 1 of axis 1]
• Reference axis ............. Axis 1
• Interpolation axis.......... Axis 2, Axis3, Axis4 (The required values are also set in
positioning data No. 1 of axis 2, axis 3 and axis 4.)

(Note): Refer to Section 5.3 "List of positioning data" for information on the setting details.
POINT
 When the "reference axis speed" is set during 4-axis linear interpolation control,
set so the major axis side becomes the reference axis. If the minor axis side is set
as the reference axis, the major axis side speed may exceed the "[Pr.8] Speed
limit value".
 Refer to Section 9.1.6 "Interpolation control" for the reference axis and
interpolation axis combinations.
