Features | AC Speed Control Motor US2 Series

Easy Operation

The digital display panel and setting dials allow for intuitive operation.
It is so simple to use that anyone can master it without looking at the manual.

Video Showing How to Operate

• Simple and Intuitive Operation

  Turn the setting dial to set the desired value. Determine the rotation speed by simply pushing the setting dial.

  

• Start, Stop, and Change of Rotation Direction

  With single switch operation, start, stop, and change the rotation direction. There is no need to install an external switch.

Simple Wiring

Just connect the motor and speed controller, connect to the power supply to start up immediately.
The speed controller has connectors and a built-in capacitor, which eliminates troublesome wiring and connections.

• Maximum Extension Distance 10 m

  Easy connection between motor and speed controller via connector.
  The distance between the motor and speed controller can be extended up to 10 meters.

  

• Built-In Capacitor

  The built-in capacitor reduces the need for wiring, and saves space.

  

High Reliability

Low Noise and Simple System Configuration

The motors and speed controllers used in the US2 Series generate almost no noise.
As a result, fewer noise-suppressing accessories are needed, for less installation effort, cost reduction, and space saving.

Speed Control Using Closed Loop Control

Stable Operation Even When Load Fluctuates

By constantly checking the rotation speed with the tachogenerator built-in to the AC motor, it is controlled to maintain the setting speed even when the load fluctuates. In addition, the digitalization of the control circuit has improved the speed regulation from -5 % to ±1 % (reference value).

Useful Functions

Video showing useful functions

Open the Front Panel to Set Various Functions

• Digital Display
  Monitoring information and alarm codes can be displayed.
• Equipped With Indicator
  Can be set to show the rotation speed of the gearhead output shaft, or conveyor transfer speed.
• Operation Method Selection
  Select whether to operate by the switch on the front panel or by external commands.
• Data Protection (Lock)
  Lock the data setting so that the set rotation speed cannot be changed.

Smooth Operation When Starting and Stopping

Motor acceleration time can be set with the acceleration/deceleration time potentiometer.

Setting time 0.1~15 seconds (Factory Setting: Fixed at 1 second)

Protection of Motor and Speed Controller

Protects the motor and speed controller with an alarm display if motor generates abnormal heat, has a poor connection, or locks up.

Use of a High Permissible Torque, High Strength Gearhead

Uses a motor and gearhead that excels in both permissible torque and strength.

Right-Angle Hollow Shaft Hypoid JH Gearhead

High strength hypoid gears are used. Significant torque enhancement and noise reduction compared to conventional products are achieved.
The radial and axial loads on the gearhead output shaft are also greatly increased, contributing to the downsizing and enhanced reliability of the equipment.

Parallel Shaft Gearhead GV Gearhead

By increasing the size of the output shaft bearing and using carburized gears, the permissible torque and permissible radial and axial loads have been increased compared to the conventional gearhead.

Right-Angle Hollow Shaft Hypoid JH Gearhead/Right-Angle Solid Shaft Hypoid JL Gearhead

• Motor Mounted Perpendicularly to Drive Shaft for Space Saving

  

• Cost Reduction by Directly Linking to the Drive Shaft

  

Installation Inside the Conveyor Saves Even More Space

Conveyor drive rollers can be installed on both ends of the load shaft of a hollow shaft type.
The equipment can be made even smaller compared to when the motor is installed on the side of the conveyor.

Easy Installation With Torque Arm

• The torque arm (sold separately) further reduces installation time and effort. (Hollow shaft type)

  

  • Easily centered with the equipment
  • Only one needed to stop rotation and secure the equipment
