AR Series

AC Input FLEX LOGO Built-in Controller Type

The AR Series substantially reduces heat generation from the motor through use of high-effi ciency technology. A pulse input type and a newly released built-in controller type are available.

Adopting Oriental Motor’s Original Closed Loop Control

The AR Series uses our closed loop control to maintain positioning operation even during abrupt load fluctuations and accelerations. The rotor position detection sensor monitors the rotation. When an overload condition is detected, the AR Series will instantaneously regain control using the closed loop mode.

Continuous Operation is Achieved Due to the Reduction of Motor Heat Generation by Utilizing High-Effi ciency Technology

Lower Heat Generation

The AR Series utilizes high-efficiency technology to achieve a significant reduction in the amount of heat generated from the motor.

●Temperature Distribution by Thermography

●Motor Case Temperature under Same Operating Conditions


Power consumption: up to 66% less✽ than a conventional model

Types of Operation Systems

Stepping motor and driver packages combine a stepping motor selected from various types with a dedicated driver. In addition to the pulse input type, drivers with a built-in controller type is also available.

Built-In Controller Package

The burden on the programmable PLC is reduced because the information necessary for motor operations is built into the driver. This simplifies the system configuration for multi-axis control. Set with control module (sold separately), data setting software, or RS-485 communication.

Operation type

With built-in controller packages, the motor’s operating speed and traveling amount are set with operating data and operations performed based on the selected operating data. The operation type is 4-pattern.

Positioning Operation
Return-To-Home Operation
Continuous Operation / Other Operations

Group Sending Function

(Via RS-485 communication or Network Converter)

Groups can be configured with multiple axes connected via RS-485 communication, and commands sent for each group. Multiaxis simultaneous starting and identical operations are also possible.

Teaching Function

Teaching can be done using the control module OPX-2A (sold separately) or data setting software MEXE02✽. The table is moved to the desired position, and the position data at that time stored as the positioning data.

※Data setting software also distributes a CD-ROM. Request from our website or contact the nearest dealer or sales office for details.
