AZX Series Servo Motors 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.

Battery-Free Absolute Encoder Equipped Servo Motor

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.

Advantages

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.

Advantages

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

Planetary Gear Servo Motors (PS)

High Performance Geared Servo Motors

These geared motors with high permissible torque fully utilize the motor output torque.

Speed-Torque Characteristics

Low Backlash

The backlash is 15 arc minutes (0.25°) max. These motors can be used in a wide range of applications.

Electromagnetic Brake Option

These motors incorporate a non-excitation type electromagnetic brake. When power is accidentally cut off due to a blackout or other unexpected events, the electromagnetic brake holds the load in position to prevent it from dropping or moving.

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.

Sequence Function

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.

Basic Operations

AZX Series AC Input Drivers

The AZXD Servo Motor Drivers 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. These drivers are EtherCAT or EtherNet/IP-compatible. The host control device and driver can be connected with one EtherCAT or EtherNet/IP communication cable, reducing wiring. Advanced operation and function control are included through our MEXE02 software (free download). The basic operations are the same as the AZ Series, making combined use of equipment easy.
