NJ/NX-series CPU Unit Motion Control User’s Manual (W507)
6-1 Introduction
The NJ/NX-series CPU Unit can perform both sequence control and motion control.
Write motion control instructions into the user program to perform motion control with EtherCAT slave
Servo Drives, NX-series Position Interface Units, and other devices.
Programs that contain motion control instructions are called motion control programs.
You must assign Axis Variables to EtherCAT slave Servo Drives and NX-series Position Interface Units.
If you do not assign Axis Variables, assign device variables in the same way as for a general-purpose
slave. Motion control instructions can be used in the primary periodic task, in a priority-5 periodic task,
and in a priority-16 periodic task.
Version Information
With the Sysmac Studio version 1.09 or higher, you can assign device variables to the I/O ports
of slaves and Units that are assigned to the Axis Variables.
Refer to 2-4-2 Relationship between EtherCAT Master Function Module and MC Function Mod-
ule for details.
