Chapter 9 Major Positioning Control
Positioning data setting examples
[When "4-axis speed control (forward run: speed 4)" is set in the positioning data
No. 1 of axis 1]
• Reference axis............. Axis 1
• Interpolation axis.......... Axis 2 to Axis 4 (The required values are also set in
positioning data No. 1 of axis 2 to axis 4.)
