5-2-2 Axis Basic Settings
*1 The range of axis number is 0 to 7 for a CPU Unit with unit version 1.05 or earlier.
*2 The range is 0 to 3 for a CPU Unit with unit version 1.05 or earlier.
For the NX701 CPU Unit, the axes to use are assigned to either of the primary periodic task or priority-
5 periodic task.
Additional Information
The Motion control setting is not available for the NX102 CPU Unit, NX1P2 CPU Unit, and
NJ-series CPU Unit, which support only the primary periodic task.
The following table describes the different axis types that you can select in the Axis Type parameter.

Axis Types
Axis type Description
Servo axis These axes are used by the EtherCAT slave Servo Drives and NX-series Position
Interface Units.
*1
They are assigned to actual Servo Drives or other devices.
One Servomotor is used as one axis.
If you use NX-series Position Interface Units, you can assign more than one device,
such as a Pulse Output Unit and Digital Input Unit, to the same axis.
Virtual servo axis These virtual axes exist only inside the MC Function Module. They are not used by
actual Servo Drives. For example, they are used as master axes for synchronizing
control.
Encoder axis These axes are used by the EtherCAT slave Encoder Input Terminals and NX-
series Position Interface Units.
*2
An encoder axis is assigned to an actual encoder
input terminal or other device.
If one encoder input terminal contains two counters, each counter will act as one
axis.
Virtual encoder axis These virtual axes are used for encoder operation. A virtual encoder axis is used
temporarily in place of an encoder axis when there is no physical encoder.
