Axes Group Variables are system-defined variables for the setting information and the monitoring infor-
mation, such as the actual position and error information, for the axes groups controlled by the MC
Function Module. When you create axes groups with the Sysmac Studio, Axes Group Variables are reg-
istered in the variable table in the order that the axes groups are created. Axes Group Variables are
structures with a data type of _sGROUP_REF.

Axes Group Variable Names
Each Axes Group Variable in the MC Function Module has two variable names: The Axes Group
Variable name in the system-defined variables and the Axes Group Variable that is assigned when
the axes group is added on the Sysmac Studio. The Axes Group Variable names in the system-
defined variables are
_MC_GRP[0] to _MC_GRP[31] .
When you add axes groups on the Sysmac Studio, MC_Group000 to MC_Group031 are set by
default for _MC_GRP[0] to _MC_GRP[31] . The numbers are assigned in the order that the axes are
added. You can change each of these Axes Group Variable names as required from the Sysmac
Studio.
You can use either the Axes Group Variable names for the system-defined variables or the Axes
Group Variable names that are set on the Sysmac Studio to specify the Axes Group Variables in the
user program.
* An error will occur if you change the names in the AT column in the global variable table on the Sysmac Studio.
