Integrated Structure of αSTEP and Ball Screw

Achieve Highly Accurate Positioning by Combining the Highly Accurate αSTEP With a Ball Screw

By integrating the hollow rotor and ball screw nut without using couplings or other connecting parts, the rigidity of the parts and the effect of backlash due to combining are reduced.

αSTEP AZ Series Drive Motor Equipped

• Features a built-in battery-free absolute encoder with no external sensors required for continuous monitoring of the motor position
• High reliability with closed loop control
• High efficiency technology reduces motor heat generation and saves energy

Allows Stable, Fine Feed

Equipped with αSTEP, which enables stable repetition of finely-detailed movements, 1 step at a time. Ideal for fine adjustment of cameras and lenses.

Smooth Low Speed Operation

The microstep drive and smooth drive function^* reduce vibration at low speed and allow for smooth movement. Ideal for drive shafts that stably supply solution from a syringe.

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

Contributes to Size and Weight Reductions of Equipment

The compact body with integrated αSTEP and ball screw can contribute to reducing equipment size and space saving.
The reduced weight at the end of the equipment is expected to increase design flexibility.

Any Combination of Types and Additional Functions is Possible.

Table Type

This product has high rigidity guide that can fix the load to the cylinder.
Directly installing the load is easy.

Rod Type

The compact shape without any guide allows direct integration into equipment.
This product can be used as a compact thrust shaft in the guide section of equipment for load transportation.

Products With Additional Functions Such as Ball Screw Covers and Mounting Plates are Available

With Ball Screw Cover

The product can be supplied with a ball screw cover for simple dustproofing.

With Mounting Plate

Products with mounting plates are available. 2 product lines are available: one for mounting from the back face using a flange, and the other for mounting from the top using a foot.

Reduces Startup Time

Compact Body Houses Entire Linear Motion Mechanism

As there is no need to make the parts in-house, the time required for “equipment design and parts selection” and “assembly and accurate mounting adjustment” can be reduced, leading to more efficient equipment start-up.

Parameters Required for Operation Already Set

Mechanical parameters such as lead and stroke are set by the ABZO Sensor at the time of shipment. After purchase, it can be set in “mm” units, contributing to reduced equipment start-up time.

No Home Sensor Required

Since position information is managed mechanically by the ABZO sensor, external sensors such as a home sensor and limit sensor are not required. Regular maintenance issues when using external sensors can also be avoided.

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)

AZ Series-Equipped Product Line

Since the motors installed are the same, the operating and maintenance methods are the same.

Electric Actuators (AZ Series equipped)

• The power supply input of the installed motor differs between Series. Please refer to each series page for the detailed product line.

• *For the LJ linear head, purchase the AZ series separately and assemble it for use.

Efficient Push-Motion Operation

Flexible Push Force and Timing

The various types of electric actuator can easily transition to push-motion operation after positioning operations are completed. In addition, push force and timing are flexible.

Note

Please refrain from performing push-motion operation with the DR Series 1 mm lead compact electric cylinders. Because the TLC signal will be output prior to completion of push-motion operation, it may not be completed normally.
Push-motion operation can be used with other electric linear slides, compact electric cylinders, and electric grippers.

Advantages

• You can set the push force and push timing to an operation data number, and then select the data number to change the settings.
• There are different ways to change the pressing phases, such as dropping the force so that the position does not shift, slowly increasing the force, or rapidly increasing the force.

• *The illustrations above are reference diagrams for the DRS2 Series of compact electric cylinders.

Can be Used With Low Speed Push-Motion

The motor can approach the load at high speed. The motor decelerates just before hitting the surface at low speed.

Advantages

• Since the pressing impact is minimal, a mechanism for shock absorption is not required.
• The motor can approach at high speed just before reaching the surface, thus reducing the takt time.

• *The illustrations above are reference diagrams for the DRS2 Series of compact electric cylinders.

Pulse Input Type Can Also be Used for Push-Motion Operation

When T-MODE input is set, push-motion operation is possible, without the overload alarm for the pulse input type being generated.
This is useful for push-motion operation while using pulse input control.

Can Detect Forgotten Load Insertion Without Any External Sensors

The presence or absence of load can be checked by the output signals (TLC output and IN-POS output) from the driver.

• IN-POS Output

  Output signal sent when positioning operations are completed.

• TLC Output

  Output signal sent when output torque reaches the torque limiting value setting during push-motion operation.

• *The illustrations above are reference diagrams for the DRS2 Series of compact electric cylinders.

Various Operating Patterns and I/O Signals (Applicable to built-in controller type drivers, etc.)

With this type, the operation data is set in the driver, then selected and executed from the host system. In addition, operation data can be combined or shifted to another operation data triggered by an internal or external ON or OFF signal.

Easy Drive From PC with Support Software MEXE02
