Mechanical Absolute Encoder Stepper Motor and DC Input Pulse Input Driver Package

.

Absolute Sensor Stepper Motor and Driver Package

Closed Loop Stepper Motor and Driver Packages -
Battery-Free, Mechanical Absolute Encoder AZ Series (Pulse Input)

The AZ Series offers closed loop control, substantially reduces heat generation from the motor and by incorporating the newly developed Mechanical Absolute Encoder, absolute-type positioning is available, without battery back-up or external sensors to buy. Advanced operation and function control is also included through our MEXE02 software (free download). The AZ Series can perform quick positioning operations over a short distance while providing smooth performance.

The AZ Series:

  • 1.65 in. (42mm) and 2.36 in. (60 mm) frame sizes
  • Wide range of gear options and electromagnetic brake
  • 24/48 VDC.
  • All packages include a 9.8 ft. (3 m) motor cable.

Advanced Technology at Affordable Prices

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.

Absolute Encoder

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 needed

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.

Newly Developed Mechanical Absolute Encoder

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

No External Sensors Required

Positional information is managed mechanically. External sensors such as home sensor and the limit sensor are not needed.

Absolute Encoder Stepper Motor

Reduced Cost
Sensor costs and wiring costs can be reduced, allowing for lower system costs.

Simple Wiring
Wiring is simplified and the degree of freedom for equipment design is increased.

Not Affected by Sensor Malfunctions
There is no concern about sensor malfunctions (when operating in environments filled with oil mist or filled with metal pieces due to metal processing), sensor failures or sensor wire disconnections.

Improved Return-to-Home Accuracy
Home position accuracy is increase because the return-to-home operation is performed regardless of any variations in home sensor sensitivity.

Driver Features

The AZ Series driver uses a standard USB cable to connect to a PC.

USB Connection

Shortened Reset Time - High Speed Return-to-Home

Because return-to-home is possible without an external sensor, return-to-home can be performed at high speed without taking the sensor sensitivity into account, allowing for a shortened machine cycle.

High Speed Return-to-Home

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.

Oriental Motor offers geared motors; motor and gearhead pre-assembled. Based on torque, accuracy (backlash) and list price, the optimal type can be selected from the various geared motors.


 

Easy Operation through the Use of the MEXE02 Data Setting Software (FREE Download)

Easy Setting and Easy Driving

Unit Setting Wizard
This is a function that allows the traveling amount, speed, etc. to be displayed and input in the designated units. It can be easily set by following the directions displayed on the screen.

Data Setting Software

Teaching and Remote Operation
Data setting software can be used to perform the home setting and also drive the motor. This can be used for teaching or test drive purposes.

Teaching Operation

Monitoring Function

I/O Monitoring
The status of the I/O wired to the driver can be checked on a computer. This can be used for post-wiring I/O checks or I/O checks during operation.

I/O Monitoring

Waveform Monitoring
The operating status of the motor (such as command speed and feedback speed), can be checked by an oscilloscope-like image. This can be used for equipment start-up and adjustment.

Waveform Monitoring

Alarm Monitoring
When an abnormality occurs, the details of the abnormality and the solution can be checked. Because the solution can be checked it is possible to respond to abnormalities quickly.
