Features | Electric Linear Slide EAS Series

Agile Responsiveness

By utilizing the high responsiveness of the closed loop stepper motor, quick short distance positioning is possible.
It also helps shorten the takt time of the equipment.

Closed loop stepper motors operate synchronously with pulse commands and generate high torque with a compact body, and offer excellent acceleration performance and responsiveness.

Stability at Low Speeds

Thanks to the microstep drive system and smooth drive function^* of the closed loop stepper motor, resolution can be improved without mechanical elements such as a speed reduction mechanism. As a result, speed fluctuation is minimal even at low speeds, leading to improved stability.

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

High Accuracy

This is an electric linear slide with ball screw and the LM guide^* manufactured by THK. This slide is suitable for applications where traveling parallelism is required because the highly accurate LM guide is directly installed to customer's enclosure base (traveling parallelism is 0.03 mm).

• *"LM Guide" is a Registered Trademark of THK Co., Ltd.

X-Table

• 

• 

  This type can reduce the intrusion of falling foreign particles when it is used in X-tables.

Y-Table

• 

• 

  This type can reduce the intrusion of falling foreign particles when it is used in Y-tables.

Avoidance of Interference With Peripheral Equipment

The mounting direction of the motor can be changed in 4 directions, allowing the cable outlet direction to be freely changed to suit the installation location.

With Sensor Rail

Battery-Free Absolute Encoder Equipped

It is equipped with a small battery-free mechanical absolute encoder (ABZO sensor). This can help improve productivity and reduce costs.

• Mechanical-Type Sensor
  Retains positioning information even when power is not supplied
• Multi-Rotation Absolute Encoder
  Absolute position detection is possible with ±900 (1,800) revolutions of the motor shaft from the home position

Simplifying the Main Program via Sequence Function

The AZ Series come equipped with a wide variety of sequence functions such as timer settings for linked operation and during operations, conditional branching, and loop operation. (excluding some models)
It can be set up using the support software MEXE02, which simplifies the sequence program of the host system.

• Positioning Operation Data Setting Value (max. 256)
• General-Purpose I/O Signal Counts (Input 10, Output 6)
• Communication I/O Signal Counts (Input 16, Output 16)

• Useful Functions and Usage of the AZ Series
• Simple Sequence and Utilization Examples for Functions

• No External Sensors Required

  As it is an absolute system, home sensors or limit sensors are not required.

  Advantages

  • Improved high-speed return-to-home + return-to-home accuracy
  • Reduced cost
  • Simple wiring
  • Not affected by external sensor malfunctions

• Battery-Free

  Mechanical-type sensors do not require batteries.
  Positioning information is managed mechanically by the ABZO Sensor.

  Advantages

  • No need to replace batteries
  • Unlimited driver installation possibilities
  • Safe for overseas shipping

Data Collection of Motor Operation Status and Functions Useful for Preventive and Predictive Maintenance

This software is equipped with various monitoring functions for checking the operating status of the motor.
By using different types of equipment for different situations, it is possible to shorten the start-up and adjustment time of the equipment, as well as to utilize it for maintenance and servicing.

Monitoring Function to Visualize the Motor Operating Status and Help Collect Data

The ABZO sensor bulit in the AZ Series allows you to monitor the motor's operating status numerically.

[Monitoring With MEXE02 Support Software]

In addition, the built-in controller type can realize data collection at a host master via industrial network.

Types of network converters and the industrial networks they support

Information Functions Useful for Preventive and Predictive Maintenance

By setting arbitrary numerical values for the monitored information items, external signals can be output when the values are reached.
Importing this information into the host controller helps in early detection of problems and adjustment of product maintenance timing.

Examples of Information Functions

• TRIP Information

  You can set the number of rotations you want to output in advance, and output when that number is reached. (Motor operation will continue)

  

• Temperature Information

  You can set the desired output temperature in advance, and the driver will output when it reaches that temperature. (Motor operation will continue)

  

Standardized Wiring, Control, and Maintenance Parts

Various actuator products equipped with the αSTEP AZ Series are available.
They each have the same motor and driver, which allows for standardized wiring, control, and maintenance parts.

Wiring Standardization

The wiring for motor cables, I/O signals, and power supply is the same.

Control Standardization

These products can be operated via the same method, since the control method is the same. For the network control, the remote I/O and the command code are also the same. It saves you the trouble of creating a program.

Unification of Maintenance Parts

Maintenance parts can be minimized, since the motor, driver, and cable are common to all. Management costs (parts cost, management space) can be reduced.
