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 Rigidity

High Permissible Moment

This series is compact yet effective in handling high moment loads.

High Permissible Moment

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.

Space Saving

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.

Cable Direction

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.

Low Dust Generation


Application Example

Application Example

High Speed Driving

High Response

By utilizing the high response of the stepper motor, short distances can be covered quickly. Movement follows commands without delay.

High Response

Short-Distance High-Speed Driving Even with Heavy Loads

By combining the high response characteristic of stepper motors with a highly rigid guide, high-speed operation even under heavy loads becomes possible.

High Speed Operation

Smooth Movement Even at Low Speeds

Reduced vibration and smooth movement is possible thanks to the standard microstep drive system and smooth drive functions*.

*The smooth drive function automatically microsteps based on the same traveling amount and speed used in the full step mode, without changing the pulse input settings.

Smooth Movement

Reversed Motor Type

Reversed Motor Type

With overall lengths up to 136.4 mm shorter compared to the straight type, reversed motor types can contribute to equipment space-saving.

Reversed Motor

Simple Maintenance for Reversed Motor Type

Maintainability has been improved by using Oriental Motor's unique belt tension adjustment mechanism and through the standardization of maintenance parts based on the AZ Series.

Thanks to Oriental Motor's unique belt tension adjustment mechanism, belt replacement is easy.

If the screw is loosened, the belt tension is adjusted to an appropriate value by the force of the spring.

Simple Maintenance


Electromagnetic Brake

Vertical operation is possible with electromagnetic brake. The load position can be held when the power is cut off. Since the work will not fall in case of power failure or disconnection, you can safely use equipment in which the work moves vertically.

Vertical Operation

 

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 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.

High-Speed Return-to-Home

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.

No Return-to-Home Required

Mechanical Type Absolute Encoder Motor

Advanced Technology at Affordable Prices

Mechanical Absolute Encoder

Oriental Motor has developed and patented a compact, low-cost, battery-free mechanical type absolute sensor. The AZ Series is available at affordable prices and can contribute to improved productivity and cost reductions.

Mechanical-Type Encoder (No Battery Required)

A mechanical sensor composed of multiple gears is employed. Positioning information is detected by recognizing the angle of the individual gears. As a result, it does not require a battery.

Multiple-Rotation Absolute System*

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

Home Setting Method*

The home position can be easily set by pressing a switch on the drivers surface, which is saved by the Mechanical Absolute Encoder. In addition, home setting is possible with the MEXE02 data setting software or external input signal.

Home position is easy to adjust by moving the motor to a desired position manually.

HOME Setting Switch

*Requires AZ Series Driver

No Battery Required

No battery is required thanks to a mechanical-type sensor. Because positioning information is managed mechanically by the Mechanical Absolute Encoder, the positioning information can be preserved, even if the power turns off, or the cable between the motor and the driver is disconnected.

No battery required

 

Reduced Maintenance

Because there is no battery that needs replacement, 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 box.

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 Mechanical Absolute Encoder does not require a battery, so there is no limit 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.

Position Holding Even when the Cable between the Motor and Driver is Detached

Positioning information is stored within the Mechanical Absolute Encoder.

*Because the positioning information is stored in the Mechanical Absolute Encoder, the home position must be reset if the motor is replaced.

High Reliability

High Reliability is provided by using the control method unique to Oriental Motor that combines the merits of both open loop control and closed loop control.

Continues Operation Even with Sudden Load Fluctuation and Sudden Acceleration

In normal conditions, it operates synchronously with pulse commands under open loop control, and because of its compact size and high torque generation, it has excellent acceleration performance and response. In an overload condition, it switches immediately to closed loop control to correct the position.

Alarm Signal Output in Case of Abnormality

If a continuous overload is applied, an alarm signal is output. Also, when the positioning is completed, a signal is output. This provides high reliability.

No Tuning Required

Because it is normally operated with open loop control, positioning is still possible without gain tuning even when the load fluctuates due to the use of a belt mechanism, cam or chain drive, etc.

Holding the Stop Position

During positioning, the motor stops with its own holding force without hunting. Because of this, it is ideal for applications where the low rigidity of the mechanism requires absence of vibration upon stopping.


Energy Saving

Heat generation is reduced thanks to the high efficiency motor, resulting in energy savings.

Lower Heat Generation

Heat generation by the motor has been significantly reduced through higher efficiency.
