High Reliability

Low Noise Gives Peace of Mind and System Configuration is Simple

Low Noise

Alarm Output Increases Reliability

Thanks to the closed loop control, feedback on the motor status is provided to the controller in real-time. An alarm signal is output when an abnormality, such as motor lock due to overload, occurs and the supply of power to the motor is stopped.

Continuous Duty Range

Continuous operation is possible in this region within the specification rating.

Simple Interface

Closed Loop Control

With a built-in tachogenerator on the back of Oriental Motor's Speed Control motors, the output speed of the AC motor is supplied to the Controller ensuring accurate speed control along with alarm warnings if any abnormalities occur.

Closed Loop Control

Speed Regulation (Load) is Improved

By making the control circuit CPU-controlled, the speed regulation (load) has improved. It is possible to make the deviation for the speed command and speed detection values almost 0, and the speed regulation has been improved from -5% to ±1%*. *Permissible torque when at 1000 r/min.

Parallel Motor Operation (20 Units Max.)

A single external speed potentiometer can operate a maximum of 20 units in parallel. Fine adjustment of each motor's speed can be performed by changing the controller's parameters.

Parallel Motor Operation

Speed Control (4 speeds)

4 units of operating data can be set, and can be switched with I/O during operation.

4 Speed Settings


Makes the motor movement at start/stop smoother. It is possible to set acceleration/deceleration differently for each of the 4-speed data units.

Acceleration / Deceleration

Bi-Directional Operation

Performs the operation according to the command for rotation direction.

Bi-Directional Operation

Instantaneous Bi-Directional Operation

Instantaneously switches the rotation direction of the motor while operating. (Short cycle change conditions can be created)

Instantenous Bi-Directional Operation

Speed Range Control

It is possible to limit the speed setting in advance with speed range.

Speed Control Range

Instantaneous Stop

Stops the operating motor instantaneously. (Short cycle run/stop conditions can be created)

Instantenous Stop

Compact, Easy Installation


The controller volume is 63% smaller than a general inverter.

Compact Controller

Side-by-Side Installation Saves Space

The body width is 1.38 in. (35 mm) and even when using multiple speed controllers, the installation is compact because they can be installed side by side.

Side-by-Side Mounting

Slim Body Control Box

The speed controller depth is 3.54 in. (90 mm). It can be installed in slim body control cabinets.

Slim Body

Easy DIN Rail Installation

The speed controller can be installed directly on the DIN rail.

DIN Rail Mounting

Connecting the Motor and Driver is Easy using a Connector

Wiring the speed controller and motor together uses a connector, so installation and removal are easy.

Easy Connection

Screwless I/O Wiring Requires No Crimping or Screwing

No need for soldering or crimping tools, and no torque management for screws is necessary. This reduces wiring time and maintenance.

Easy Wiring


External Speed Potentiometer

External Speed Potentiometer

Sets and adjusts the motor's speed.

(20 kΩ, 1/4 W and with a linear resistance vs. angle curve)


Potentiometer Mounting Plate

DIN rail mounting bracket for the external speed potentiometer.


General Purpose I/O Cables

Driver Cable

It is a general-purpose multi-core cable convenient for connection between the driver and host controller.

Capacitor Mounting Bracket

Capacitor Mounting Bracket

This capacitor mounting plate allows you to attach an AC motor or Fan motor’s capacitor on a DIN rail. You can attach or detach in on a DIN rail with a one screw. There is no need for a separate end plate or additional components.

Capacitor Connector Lead Wires (5 Sets)

Capacitor Lead Wire Set

Lead wire set for AC motor capacitors.

  • 5 sets 1 part number = 5 sets (10 lead wires).  5 White / 5 Red
  • Be sure to use capacitor cover
