The αSTEP AR Series uses Oriental Motor's 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. When an overload condition continues, the AR Series will output an alarm signal, thereby providing reliability equal to that of a servo motor.
The driver is equipped with an automatic recognition function, which recognizes the attached motor. Various types of motors, such as the standard type and the geared type, can be attached to a single driver. Therefore, there is no need to change the driver to match the motor to be attached. Maintenance is easier.
All of the products equipped with the αSTEP AR series feature standardized controllability.
In addition to the microstep drive system, the αSTEP AR Series also uses the smooth drive function to allow for smoother motion. The smooth drive function automatically implements microstep drive based on the same travel amount and speed used in the full-step mode, without changing the pulse input settings.
The αSTEP AR Series uses improved current control technology to improve the stop position accuracy of the stepper motor. The result is greater position accuracy.

The αSTEP AR Series maintains all of the benefits of a stepper motor.
High Response
The stepper motor operates synchronously with pulse commands to achieve high response. There's no delay in operation following a pulse command.
Capable of Driving Large Inertia Loads
Compared to a servo motor of the same frame size, a larger inertial load can be driven regardless of speed conditions.
No Hunting / No Tuning
Because it uses a stepper motor, the αSTEP AR Series does not hunt when stopped. Accordingly, the AR Series is ideal for applications where the equipment uses a belt-drive mechanism or otherwise has low rigidity and you don't want it to vibrate when stopping.
With the αSTEP AR Series, you can perform positioning quickly after a load change, etc., without adjusting any gains.
A separate circuit is not needed to control the electromagnetic brake. The electromagnetic brake is released when the motor is excited (=current ON input is turned ON), and activated to hold the load in position when the excitation is cut off (=the current ON input is turned OFF).
The AR Series is recognized by the UL/CSA Standards and bears the CE Mark as proof of conformance to the Low Voltage and EMC Directives.
The AR Series complies with the SEMI Standard on power supply voltage drop, and accordingly this motor can be used effectively in semiconductor manufacturing apparatuses. The customer is advised to always evaluate the stepper motor on the actual equipment.
The control power-input terminals are provided separately from the main power terminals. This means that even when the main power is cut off due to an emergency stop, etc., you can still detect current position and check information on each alarm, etc., as long as the power (24 VDC) is supplied to the control power-input terminals.
You can combine a control module (OPX-2A) (sold separately) or data setting software* (MEXE02) both to change parameters, add functions and perform various monitoring operations according to the needs of your system.
*Cable for connection to PC required for MEXE02 data setting software (sold separately**- see Accessories).
**One FREE CC05IF-USB communications cable is available per customer, contact Technical Support for more information.
Two return operation functions are available: return to electrical home operation and automatic return operation. With these options, you can easily set up your system to return home when the main power has been cut off due to an emergency stop, etc., or the motor excitation has been turned off.
While the main power is cut off, the control power (24 VDC) must be supplied in order to maintain positioning.
Return to Electrical Home Operation
An operation in which the motor returns to the "position it had assumed when the power was turned on (=electrical home)" or "location set as the electrical home".
Automatic Return Operation
An operation in which the motor returns to the "position at which motor excitation was turned off (= the C-ON input turned OFF or FREE input turned ON)."
You can input pulses to perform push-motion operation where the load continuously has force applied to it. The amount of force (motor output torque) is set by the push-motion operating current value. Using a control module (OPX-2A) or data setting software (MEXE02) (both sold separately), change the applicable parameter to "Push-motion operation" turn the T-MODE input ON, and input pulses. The motor will start the push-motion operation.
A built-in pulse generator allows the motor to be driven by connection to a PLC or other devices with connection through a Factory Automation (FA) network via I/O control. Modbus (RTU) control, or a network converter.
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.
FLEX is the generic name for products that are used for Factory Automation (FA) network control via I/O control, Modbus (RTU) control, or a network converter.
FLEX products enable easy connection, easy control, and reduce the complexity of system configuration.
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.
