Features of Actuator Section
Take the AZ Series as an example, and show the features of the DGII Series.
Direct Load Fastening is Possible
Loads with large inertia such as tables and arms can be installed directly on the output table, eliminating the need for connecting parts (collars), reducing design and assembly effort and parts costs.
Large-Diameter Hollow Output Table
Hollow holes can be used for wiring cables and for air and liquid piping.
High Strength
Can Drive Heavy and Large Loads
Maximum permissible axial load is 4000 N. Maximum permissible moment is 100 N·m. It can drive even a load with a large mass or inertia.
Small Surface Runout
Loads can be placed away from the center of the output table.
High Positioning Accuracy
| Motor Vertical Mounting | Motor Horizontal Mounting | |
|---|---|---|
| Backlash | Non-backlash | 6 arcmin (0.1°) |
| Repetitive Positioning Accuracy | ±15 arcsec (±0.004°) | ±30 arcsec (±0.008°) |
Integrated Structure to Reduce Equipment Setup Time
Reduce the Time Required for "Design," "Assembly," and "Adjustment"
Equipment tables and arms can be installed directly on the output table.
High Power Drive With Cross Roller Bearings
- The figure above shows the motor vertical mounting structure. As for the structure of the hollow output table, the same applies to the motor horizontal mounting.
Use According to the Space
Motor vertical mounting and motor horizontal mounting types are available. It can be selected according to the installation space in the equipment.
Advantages of Motor Horizontal Mounting
- Machining of motor clearance hole is not necessary, thereby simplifying the installation plate.
- Cables, pipes, etc. can be routed between the legs under the table.
Selectable Mounting Direction
The DGII Series can be installed horizontally, as well as on ceilings and walls, giving more options for equipment design.

Advantages of Equipping With αSTEP AZ Series
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
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 Malfunction
Battery-Free
Mechanical 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
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)
Convenient Operation and Setting
The AZ Series features allow you to drive:
Reduce Takt Time With Shortcut Operations
Move the shortest distance toward the set target position.
Example)
Moving from the 0˚ position to 270˚, the shortest counterclockwise rotation direction is automatically selected and driven.
Set No-Entrance Area
Ensure equipment is not damaged by collisions with obstacles and work area is maintained.
Infinite Multi-Rotation is Possible
Equipped with a wrap function that can automatically reset the current position to "0°." Infinite multi-rotation operation is possible.
Reduces Equipment Setup Time
The parameters required to operate the hollow rotary actuator are set at the time of shipment. Contributes to reduced equipment setup time.
[Example of parameters set at the time of shipment]
- Home position
- Resolution (0.01°/step)
- Setting the rotation direction of the output table
- Wrap function setting (±180°)
- *Each initial value can be changed.
Applications and Usage Examples
Applications Dealing With Load Moments
Low Speed and Low Vibration Applications
The microstep drive system and smooth drive function allow for low vibration rotary operation, even at low speeds.
Example) Liquid dispensing equipment
Even at low speed, stable and even dispensing is possible.
For High Precision Positioning Applications
It does not cause the phenomenon called "hunting," in which the shaft moves minutely when stopping. This is ideal for applications where vibration when stopping is a problem.
Example) Image inspection equipment
Accurate images can be captured because there is no hunting.
Applications With Varying Load Inertia
Since gain adjustment is not required, even for equipment with load fluctuations, can operate as set without the need for tuning.
Example) Disk manufacturing equipment
No tuning is required even if the number of discs to be transported changes.
