6-6-2 System for System-defined Variables for Motion Control
 Derivative Data Types
Refer to the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501) for details on the
other data types that are used by an NJ/NX-series Controller.
The attributes that are shown in the following table are the same for all system-defined variables for
motion control.
* Variables are published on the network with the variable names of the system-defined variables. The variable
names that are created when the axes or axes groups are created on the Sysmac Studio are not published to the
network.
System-defined variables for motion control consist of information representing the status of the MC
Function Module, status information for slave devices connected via EtherCAT communications and
NX Units mounted on the CPU Unit, and the portion of the MC parameter settings used to perform
motion control.
You can access system-defined variables for motion control as variables in the user program and
monitor them from the Sysmac Studio.
Type Description
Enumerated data types This data type uses one item from a prepared name list as its
value. Variables with this data type start with “_e.”
Structure data type This data type consists of multiple data types placed
together into a single layered structure. Variables with this
data type start with “_s.”
