Derivative Data Types
Refer to the
NJ-series CPU Unit Software User's Manual
(Cat. No. W501) for details on the other
data types that are used by an NJ-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
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.
System-defined variables for motion control are updated every primary period.
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.”
