Speed Control Using Closed Loop Control

Speed Regulation ±1 % (Reference value)

Rotation speed is always monitored by the tachogenerator built into the AC motor.
The actual speed is controlled to match the speed setting, even when the load fluctuates.

Digitalization of Circuits

Most of the analog circuits that were used in the past have been digitized, which is now run by the CPU, and circuit components have been vastly reduced. Unprecedented miniaturization and low cost have been achieved. In addition, digitization has made it possible to keep the deviation between the speed command value and the speed detection value close to zero, and the speed regulation has been improved from -5 % to ±1 %^*.

• *When the torque value is changed from 0 N·m to permissible torque (at 1000 r/min)

Easy Setting, Less Space

• Compact

  The volume is 63 % smaller than a general inverter.

  

• Side-by-Side Installation Saves Space

  The body width is 35 mm, and even when using multiple axes, the installation is compact because they can be installed side by side.

  

• Slim Body Control Cabinet

  Depth is 90 mm. It can be installed in slim body control cabinets.

  

• One-Touch Operation of Connector Connection between Motor and Driver

  Wiring the speed controller and motor together uses a connector, for easy installation and removal.

  

• Wiring for I/O, etc. is Done in a Screwless Manner Without Crimping or Screwing

  No need for soldering or crimping tools, and no tightening torque management for screws necessary. Reduces wiring time and maintenance.

  

• Easy Installation to DIN Rail

  The speed controller can be installed directly on the DIN rail.

  

High Reliability

Low Noise Gives Peace of Mind, and System Configuration is Simple

Alarm Output Increases Reliability

Thanks to the closed loop control, feedback on the motor status is provided to the controller in real-time. An alarm signal is output when an abnormality, such as motor lock due to overload, occurs and the supply of power to the motor is stopped.

Vertical Operation is Possible With Electromagnetic Brake Type

Speed control in vertical operation is possible through deceleration control.

Refer to here for description of deceleration control and driving conditions during deceleration control.

• Speed Control (4 speeds)

  4 units of operation data can be set, and can be switched with I/O during operation.

• Acceleration/Deceleration

  Makes the motor movement at start/stop smoother.
  It is possible to set acceleration/deceleration differently for each of the 4-speed data units.

• Bi-Directional Operation

  Performs the operation according to the command for rotation direction.

  

• Instantaneous Stop

  Stops the operating motor instantaneously.
  (Short cycle run/stop conditions can be created)

• Instantaneous Bi-Directional Operation

  Instantaneously switches the rotation direction of the motor while operating.
  (Short cycle change conditions can be created)

  Repetitive operating cycle

  

• External Speed Setting is Available

  As well as setting with the operation keys, setting with an external speed potentiometer (sold separately) or external current voltage is possible.

• Multi-Motor Control (20 units max.)

  A single external speed potentiometer can operate a max. of 20 units in parallel.
  Fine adjustment of each motor's speed can be performed by changing the controller's parameters.

  

• Speed Range Control

  It is possible to limit the speed setting in advance with the speed range.

  

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.

Motor and Gearhead Preassembled (Right-angle hypoid JH/JL gearhead, parallel shaft gearhead GV gearhead)

• The motor and gearhead are delivered pre-assembled

  This allows customers to reduce assembly time and install it in equipment right away.

  

• The Gearhead Can be Removed

  The motor position can be rotated by 90˚ to change the direction of the lead wire extraction. In addition, the gearhead only can be purchased to change the gear ratio or replace during maintenance.
