2-4 Sequence Control and Motion
Control
This section describes the sequence control and motion control systems that are used by the CPU Unit.
The NJ-series CPU Unit can perform both sequence control and motion control.
You execute sequence control with instructions other than motion control instructions in the user pro-
gram. Sequence control is for EtherCAT slaves and CJ-series Units that are not assigned to axes. Con-
trol is performed by the PLC Function Module and the EtherCAT Master Function Module.
You perform motion control with motion control instructions in the user program for EtherCAT Servo
Drive and encoder input slaves that are assigned to axes. Control is performed by the PLC Function
Module, Motion Control Function Module, and the EtherCAT Master Function Module.
