Newly Developed ABZO Sensor

This is the battery-free mechanical absolute encoder. This can help improve productivity and reduce costs.
Both motor and driver are available at reasonable prices.

Mechanical-Type Sensor

The ABZO Sensor is equipped with multiple gears and detects position information by recognizing the angle of individual gears.
As a result, it does not require a battery.

Multi-Rotation Absolute Encoder

Absolute position detection is possible with ±900 revolutions (1800 revolutions) of the motor shaft from the reference home position.

• *±450 revolutions (900 revolutions) for products with 20 mm, 28 mm (30 mm) frame size.

No External Sensors Required

As it is an absolute system, external sensors such as a home sensor or limit sensor are not required.

Improved High-Speed Return-to-Home + Return-to-Home Accuracy

Return-to-home can be performed without home sensor or limit sensor. It reduces machine cycling, achieving high speed return-to-home without worrying about sensor sensitivity. At the same time, variations in the home position due to sensor sensitivity will no longer occur. It improves home accuracy.

Reduced Cost

Does not incur external sensor or wiring costs. It reduces the cost of the entire system.

Increased Flexibility in Designing Equipment

Saves space that was previously required to install and wire external sensors. It improves the flexibility of equipment designs.

Not Affected by External Sensor Malfunctions

Eliminates malfunctions, failures, and disconnection of external sensors, which can occur in environments where metal chips may fly when machining metal, or oil mist is present.

Battery-Free

Mechanical-type sensors do not require batteries. Manages position information mechanically.

Holding Positioning Information

Position information is retained even if the power is interrupted or the cable between the motor and driver is disconnected during positioning operation.
Reduces the time required for return-to-home operation.

Reduced Maintenance

No need to replace batteries. Reduces maintenance time and costs.

More Flexibility in Driver Installation

Saves space that was previously required to install batteries and wiring. There are no restrictions on driver installation locations, improving design flexibility for the layout of control cabinets, etc.

Safe for Overseas Shipping

As batteries will self-discharge, care must be taken when the equipment requires a long transportation time, such as when being sent overseas. The ABZO Sensor has no limit for how long position information is saved. In addition, there is no need to consider the various regulations applicable when exporting batteries overseas.

Driven by Open Loop Control in Normal Operation, Closed Loop Control in Overload Operation

The system is driven by open loop control during normal operation, which offers a variety of advantages.
In case of overload, the system automatically switches to closed loop control to prevent abnormal shutdown.

Advantages of Open Loop Control

Moves in Sync With Commands Without Gain Adjustment

Even mechanisms with low rigidity, such as a timing belt, can follow commands without adjustment.

Runs in Sync With Commands Even if Load Conditions Change

Even mechanisms with large load fluctuations, such as cams, can follow commands without adjustment.

No Hunting

It can also be used safely in applications where slight vibration at motor standstill may be a problem.

Advantages of Closed Loop Control

In case of overload, the motor is controlled to maximize torque. Avoid problems such as motor stoppage due to insufficient torque.

Full Range of Monitoring Functions

Sensors are mounted on the motors so that position and speed information can be constantly monitored.
It also includes a "positioning completion signal" that is useful for monitoring the operating status.

Two Connection Methods Are Available for Motors

Connector Type (IP66 rating) for Usage in Wet Conditions

With a degree of protection IP66 rating, it has a high dust-resistant performance and can be used in wet conditions

"Splash Resistant Test" Which Takes Into Account Deterioration Over Time Original Evaluation of Oriental Motor

Connector Structure

The connector structure has a built-in gasket and O-ring for improved waterproofing. It is IP66-compliant, including the connector part.

Types and Features of Geared Type

In addition to high torque and high resolution, various advantages such as the ability to drive large inertial loads can be obtained.

Network Compatible Driver

Compatible with all major industrial networks used around the world, contributing to centralized management of equipment information and reduced wiring. AC Input Driver is superior to DC Input in terms of torque, and DC Input Driver is compact in comparison to AC Input. Find for the purpose and application.

Mini Driver (DC input only)

Mini driver designed to be more compact and lightweight than a single axis driver. Can be installed even in a small space. Due to the wide voltage specifications that can be used with the battery power supply, it is also suitable for incorporation into self-propelled equipment.
