A delicate grip is achieved by fine-tuning the grip force in 1% operating current increments and implementing a slow approach to the load.

 

A delicate grip is achieved by fi ne-tuning the grip force in 1% operating current increments and implementing a slow approach to the load.

Easily set the grip force, grip time, and speed according to the object being gripped.
Safely and reliably grip objects that may easily break, such as glass, and objects that easily deform, such as plastic or springs.

Quick Approach, Slow Grip

The motor approaches the load at high speed, then decelerates just before contacting the surface at low speed.

Grips at Low Grip Force, then Gradually Increases the Force

Pushing force and timing can be easily changed.

The grip movement of the electric gripper works by utilizing push-motion operation. The pushing force (grip force) is set according to the running current of the motor.

The minimum travel distance between the pincers - attached to the base jaws - is 0.02 mm. The direction and position of components can be coordinated by gripping them according to their size.

The Size and Presence of a Load are Determined within the Operational Range of the Pincers

The operational range of the pincer is confirmed by the output signal (TLC output, AREA output) from the driver, allowing the size and presence of a load to be determined.

Monitor the Gripper Position to Measure Size

The Coordinates Information Monitoring Function in the driver sends data from the gripper to the host PLC, allowing the size of the load to be measured.

Eliminate Extra Sensors with a Battery-Free Absolute System

The AlphaStep AZ Series Mechanical Absolute Encoder is available as a leading closed loop, battery free absolute motion solution sold as a Stepper Motor + Driver, Linear Actuator and Rotary Actuator packages allowing for absolute, battery free, advanced performance across a wide range of applications. All AlphaStep AZ Series products offer guaranteed performance are available in Pulse Input or Built-In Controller (Network) Types in AC or DC Input. A DC Input Multi-Axis Controller / Driver is also available to connect up to 4 axes with one unit.

 

 

No Home Sensor Required

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

Because it is an absolute system, no home sensor is required.

High-Speed Return-to-Home Operation

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

Reduced Cost

Sensor 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

No need to worry about sensor malfunctions, sensor damage or sensor disconnection.

Improved Return-to-Home Accuracy

Home position accuracy is increased because the return-to-home action is performed regardless of any variations in home sensor sensitivity.

Easy Home Position Setting

The home position can be easily set by pressing a switch on the front of the driver, which is saved by the absolute sensor. In addition, home setting is possible with the MEXE02 support software or by using an external input signal.

*Requires AZ Series Driver

Battery-Free

No battery is required because it is a mechanical-type sensor. Because positioning information is managed mechanically by the absolute sensor, the positioning information can be preserved, even if the power turns off, or if the cable between the motor and the driver are disconnected.

Reduced Maintenance

Because there's no battery that needs replacing, 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

With normal batteries that self-discharge, care must be taken when the equipment requires a long shipping time, such as when being sent overseas. The absolute sensor does not require a battery, so there is no limit to how long the positioning information is maintained. In addition, there's 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 absolute sensor.
