es Group Basic Settings
Set whether to use the axes group. If you are going to use the axes group, set the axis configuration
and the axes to use.
* An error occurs if you execute the MC_GroupEnable (Enable Axes Group) instruction for an axes group that con-
tains an unused axis.
The following table lists the axis compositions you can use with the MC Function Module. The default is
group disabled . Use the Sysmac Studio to set the axis composition according to the actual devices.
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 63). 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.

Composition Description
2 axes A two-axis configuration is used. For example, a machine with a two-axis Carte-
sian coordinate system is used.
3 axes A three-axis configuration is used. For example, a machine with a three-axis
Cartesian coordinate system is used.
4 axes A four-axis configuration is used. For example, a machine with a three-axis Car-
tesian coordinate system is used with a rotary axis at the end tool.
Composition Axes

2 axes Set Axis Variable names (axis numbers) for axis A0 and axis A1.
3 axes Set Axis Variable names (axis numbers) for axis A0, axis A1, and axis A2.
4 axes Set Axis Variable names (axis numbers) for axis A0, axis A1, axis A2, and axis
A3.
