AZX Series Battery Free Absolute Encoder Servo Motors

Servo Motors

Servo Motors AZX Series Equipped with Mechanical Absolute Encoder

These servo motors are equipped with a battery-free absolute encoder. They are suitable for continuous speed control or positioning applications with a large amount of travel since they achieve high torque in the high speed range. The basic operations are the same as the AZ Series, making combined use of equipment easy.

EtherNet/IP compatible


Battery Free Absolute Sensor

Battery-Free Absolute Encoder Equipped Servo Motor

Battery Free Absolute Sensor

The AZX Series is equipped with the same battery-free mechanical absolute encoder (ABZO sensor) as the AZ Series. These are dedicated servo motors for positioning and continuous operation.

  • Mechanical Type Encoder
    Holds positioning information even when powered off
  • Multi-Turn Absolute Encoder
    Absolute position detection is possible with ±900 rotations (1800 rotations) of the motor shaft from the reference home position


No External Sensors Required

Thanks to the absolute system, a home sensor or external sensor is not required.


  • High-Speed Return-to-Home + Improved Return-to-Home Acuracy
  • Reduced Cost
  • Simple Wiring
  • Not Affected by External Sensor Malfunctions

Battery Free

No Battery is necessary for a mechanical-type encoder. Positioning information is managed mechanically by the ABZO sensor.


  • No Battery Replacement Required
  • No Battery Installation Space Required (Unlimited Driver installation possibilities)
  • Safe for Oversease Shipping

Network Compatible Drivers

These drivers are EtherCAT or EtherNet/IP-compatible. The host control device and driver are connected with one communication cable, reducing wiring.

EtherNet I/P Driver

Sequence Function Simplifies Programming

AZX Series positioning operations come with a variety of sequence functions, such as a timer setting between operations and linked operation, conditional branching, and loop counting. These can be set using the support software MEXE02, which helps simplify the host system’s sequence program.

Achieves High Torque in the High Speed Range

The AZX Series achieves high torque in the high speed range. It is suitable for positioning applications with a large amount of travel (e.g.: ball screw driving).

High Torque in High Speed Range

The Basic Operations are the Same as the AZ Series

Using the AZX Series and AZ Series together in the same equipment can eliminate the work of operational changes.
