AZ Series Absolute Sensor Stepper Motor
Newly Developed Absolute Sensor
Oriental Motor has developed a compact, low-cost, battery-free mechanical type absolute sensor (patented). This can help improve productivity and reduce costs.
Mechanical-Type Sensor
A mechanical sensor composed of multiple gears is employed. Positioning information is detected by recognizing the angle of the individual gears.
Multi-turn absolute sensor
Absolute position detection is possible with ±900 rotations (1800 rotations) of the motor shaft from the reference home position.
Home Setting Method*
The home position can be easily set by pressing a switch on the driver's surface, which is saved by the Absolute Sensor. In addition, home setting is possible with the data setting software (MEXE02) or by using an external input signal.
*Requires AZ Series Driver

Electric Linear Slides
High Rigidity / High Accuracy
Despite the small size, high permissible moment loads have been achieved by using a highly rigid guide.
High Rigidity and High Accuracy Guide
The LM Guide™ from THK is used as the guide hardware. It is a thin, stainless steel guide that can withstand high moment loads. The guide also has excellent traveling parallelism, which has been reduced to 0.03 mm or less.
High Permissible Moment
This series is compact yet effective in handling high moment loads.
Space-Saving
Maximum use of space is possible because the equipment doesn't interfere with the load.
Equipment can be installed in contact with surrounding structures.
Variable Cable Outlet Direction
The motor attachment direction can be changed to any of 4 directions*, allowing the cable outlet to be changed to best suit the installation location.
*3 directions for reversed motor types.
Simple Dust-Resistant Structure
Through the use of a stainless steel, simple dust-resistant structure, simple dust-resistant infiltration of foreign objects is prevented and dust generation is also controlled.
Low Dust-Generated Roller Structure
A low dust-generation roller structure has been built into the table which provides rolling contact with the stainless steel sheet, thus preventing the generation of abrasive particles. This not only controls the generation of dust, but also improves the durability of the stainless steel sheet.
No External Sensors Required
Because the absolute motor sensor (ABZO) is built-in, there's no need for a battery to store the positioning information, or for a home sensor, or external sensors or any other external sensors.
- Cost Reduction
- Simplified Wiring
- Not Affected by Sensor Malfunctions
- Improved Return-to-Home Accuracy
High-Speed Return-to-Home
Regular Return-to-Home
With the use of limit sensors and home sensors to detect the home point at low speeds, return-to-home is time consuming.
Return-to-Home Operation of the αSTEP AZ Series
Without the need to detect using limit sensors or the home sensor, the equipment can travel directly at high speed of the home position recorded by the motor sensor.
Return-to-Home Not Required (For built-in controller type)
Since the position information is known even when the power supply is turned off, operation can resume without return-to-home after an emergency stop or power outage.

Maximize Payload in Tight Spaces
Pack high rigidity and heavy-load transport into a compact footprint. Powered by αSTEP AZ absolute encoder technology, the EZS Series delivers smooth, hunting-free linear positioning without external sensors.
Compact Electric Cylinders
Reliable Design and Structure
A hollow rotor and a ball screw nut are joined. Since no connecting parts are necessary, there is less backlash than when coupling rigidity, etc. combines other parts. Therefore, highly accurate positioning can be achieved.
High Positioning Accuracy
The ball screw nut is linked with the hollow rotor. Through the coupling rigidity and other aspects of parts combination, the impact of backlash has been minimized achieving high-precision positioning.
Ground Ball Screw
Ideal for applications where high positioning accuracy and low vibration are required, such as optical devices and semiconductor systems that use fine-feed pitches. The DR/DRS ground ball screw type achieves high reliability by maximizing the performance of a 5-phase stepper motor.
Rolled Ball Screw
Ideal for general positioning applications where reliability and ease of use are given priority. It combines the superior thrust and resolution of the ground ball screw type with greater ease of use.
Compact Body Houses Entire Linear Motion Mechanism
Since customers do not need to provide parts, the time needed for installing, designing, and selecting parts can be reduced. The number of man-hours required for assembly and adjusting the installation accuracy can be reduced, contributing to higher productivity.
Installation Time Reduced
Space Saving and Less Wiring with the Absolute Sensor
In addition to the compact and lightweight body, the motors with absolute sensors do not require a home sensor. This saves space and wiring, and lets you avoid routine maintenance or trouble caused by using a home sensor.
Efficient Push-Motion Operation
Flexible Pushing Force and Timing
The αSTEP DR/DRS2 Series can easily perform a push-motion operation after a positioning operation. Also, the pushing force and timing are adjustable.
- You can set the pushing force and push timing to an operation data No., and then select the data No. to change the settings.
-
There are different ways to change the pressing phases, such as dropping the force so that the position does not shift, slowly increasing
the force, or rapidly increasing the force.
Pressing at Low Speed
The motor can approach the load at high speed. The motor decelerates just before hitting the surface at low speed.
- Since the pressing impact is minimal, a mechanism for shock absorption is not required.
- The motor can approach at high speed just before reaching the surface, thus reducing the takt time.
Push-Motion Operation with Pulse Input Type
When T-MODE input is set, push-motion operation is possible, without the overload alarm for the pulse input type being generated.
This is useful for push-motion operation while using pulse signal control.

Streamline Your Motion Control
Cut wiring, save space, and eliminate external sensors with battery-free mechanical absolute encoding. The DR Series pairs precision linear cylinders with αSTEP AZ drivers for lightweight, hassle-free automation.
Battery-free
No battery is required thanks to a mechanical-type sensor. Positioning information is managed mechanically by the absolute sensor.
Holding Positioning Information
Even if the power shuts down during a positioning operation or
the cable between the actuator and the driver is disconnected,
the positioning information is retained. With the built-in controller
type, you can restart the positioning operation, without performing
return-to-home after an emergency stop on the production line or
a blackout.
Reduced Maintenance
Because there is no battery that needs replacing, maintenance time and costs can be reduced.
Unlimited Driver Installation Possibilities
Because there is no need to secure space for battery replacement, there are no restrictions on the installation location of the driver, improving the flexibility and freedom of the layout design of the control cabinet.
Safe for Overseas Shipping
Normal batteries will self-discharge, so care must be taken when the equipment requires a long shipping time, such as when being sent overseas. The Absolute Sensor does not require a battery, so there is no limit as to how long the positioning information is maintained. In addition, there is no need to worry about various safety regulations, which must be taken into consideration when shipping a battery overseas.
No External Sensors Required
With the use of the absolute system, external sensors such as the home sensor and the limit sensor are not needed.
High Speed Return-to-Home
Because return-to-home is possible without using an external sensor, return-to-home can be performed at high speed without taking the specifications for sensor sensitivity into account, allowing for a shortened machine cycle.
Reduced Cost
Sensor costs and wiring costs can be reduced, allowing for lower system costs.
Simple Wiring
Wiring is simplified, and the degree of freedom for equipment design is increased.
Not Affected by External Sensor Malfunctions
There is no need for concern about sensor malfunctions, sensor failures, or sensor wire disconnections.
Improved Return-to-Home Accuracy
Home position accuracy is increased because the return-to-home operation is performed regardless of any variations in home sensor sensitivity.
*If no limit sensor is installed, movements that exceed the limit values can be avoided through the use of the limits in the driver software.
Example Application
Hollow Actuators
Contributes to Easier Equipment Design
The gear-reduction mechanism employs precision gears along with a proprietary adjustment mechanism that eliminates backlash. The repetitive positioning accuracy from a single direction is ±15 sec., while lost motion in a positioning operation from two directions is 2 arc minutes. These characteristics make the DGII series the ideal choice for applications in which accurate positioning is a must.
*DGM60 features Deep-Groove Ball Bearings
Direct Coupling for Higher Reliability
Equipment tables and arms can be installed directly on the output table. This saves you the hassle and cost of designing an installation mechanism, arranging necessary parts, adjusting the belt tension, etc. when mechanical parts such as belt and pulley are used for installation.
High-precision Positioning
High-precision positioning is achieved by a combination of motor and rotary table mechanism.
