9-3 Assigning Variables
This section describes how to assign variables in the NJ-series CPU Unit to the I/O data in the Ether-
CAT Slave Terminal.
The methods that are used to assign variables in the NJ-series CPU Unit to I/O data in the Slave Termi-
nal are given below.
*1. Refer to the manuals for the specific NX Units to see which NX Units you can assign to axes.
9-3-1 Methods to Assign Variables
Method to assign variables Description Assignable Units
Assigning device variables Assign device variables to the I/O ports of the
Slave Terminal.
• EtherCAT Coupler Unit
• NX Units with I/O ports
Assigning axis variables Assign axis variables to the I/O data for the
devices in the Slave Terminal. Assign axis vari-
ables if you are using the Motion Control Func-
tion Module for control.
• Position Interface Units
• Some other NX Units
