5 Motion Control Parameters
Composition Axes
The axes that are in an axes group are called composition axes. To make it easier to reuse program-
ming with interpolation instructions for axes groups commands, logical axes (axis A0 to axis A3) are
used instead of axis numbers (axis 0 to axis 255). For the Composition Axes parameter, set the axis
numbers and logical axis numbers for the axes in the axes group. Servo axes or virtual servo axes can
be selected for logical axes.
Use the Sysmac Studio to assign axes from axis A0 for the number of axes you selected in the axis
composition.
Set axis numbers from axis A0 for each axes group if you create more than one axes group. You can
also set the same axis number in more than one axes group.

Precautions for Correct Use Precautions for Correct Use
• Assign all of the composition axes to the same task.
• If you set the same axis number for multiple axes groups, you cannot enable these axes
groups simultaneously.
• An axis for which Control Function is set to Single-axis position control only cannot be allo-
cated as an axis in an axes group.
Version Information
With a CPU Unit with unit version 1.04 or later and Sysmac Studio version 1.05 or higher, you
can set any servo axis or virtual servo axis that is set to a Used axis or an Unused axis
(changeable to used axis) in an axes group.
