  -The Most Advanced Drive Technology

  ---Maximum applicable motor capacity (kW) indicates capacity under heavy-duty (HD) rating.

  ---Capable of driving any kind of motor.
      A1000 runs not only induction motors, but also synchronous motors like IPM and SPM motors with high performance current vector control.

  --- Minimize equipment needed for your business by using the same drive to run induction and synchronous motors.

  ---Switch easily between motor types with a single parameter setting.

  

                                                  

  -Rotor Positioning without Motor Encoder

  ---Use an IPM motor to perform position control without motor feedback.
      Electrical saliency in IPM motors makes it possible to detect speed, direction, and rotor position without the use of a motor encoder.

  
  

  ---Precision positioning functionality without an up-per controller.

      Visual programming in DriveWorksEZ lets the user easily create a customized position control sequence, without the use a motor encoder.

  

  -Cutting-Edge Torque Characteristics

  ---Powerful torque at 0 Hz, without a motor encoder∗
      Once out of reach for AC drives, Yaskawa now offers advanced control features without a motor encoder. Achieve even more powerful starting torque at zero speed with an IPM motor.

  ·∗:No speed sensors or pole sensors required.

                                        

  ∗1: Achieving this torque output requires a larger capacity drive.

  ∗2: Contact your Yaskawa or nearest agent when using PM motors except SSR1 series or SST4 series motors manufactured by Yaskawa Motor Co., Ltd.

  ·High-performance current vector control achieves powerful starting torque with an induction motor.
  Powerful starting torque with an induction motor.

   

     *: Achieving this torque output requires a larger capacity drive.

  
  

  ---Loaded with Auto-Tuning Features
  

     *Auto-Tuning features optimize drive parameters for operation with induction motors as well as synchronous motors to achieve the highest performance levels possible.

     *Perfects not only the drive and motor performance, but also automatically adjusts settings relative to the connected machinery.

  
       A variety of ways to automatically optimize drive settings and performance

   

    Note: This type of Auto-Tuning is available only for motors less than 450 kW using an encoder.

   *Brand-new Auto-Tuning methods.

    A1000 continuously analyzes changes in motor characteristics during run for highly precise speed control.

  
  

  Smooth Operation

     *Smooth low speed operation thanks to even better torque ripple suppression.

  Tackling Power Loss and Recovery

   *A1000 offers two ways to handle momentary power loss.

   *A1000 is capable of handling momentary power loss for induction motors as well as synchronous motors without the use of a motor encoder.

  
  

    Speed search
    Easily find the speed of a coasting motor for a smooth restart.
    Applications: Perfect for fans, blowers, and other rotating, fluid-type applications.

  

  KEB

  Keep the motor running without allowing it to coast.
  Applications :Highly recommended for film lines and other applications requiring continuous operation.

  

  Note: Requires a separate sensor to detect power loss.
  The drive may trip depending on load conditions, and the motor coast to stop.

  ·Ride through power loss for up to 2 seconds.∗
  Crucial for semi-conductor manufacturers
  No need to purchase a backup power supply
  Detects, outputs an undervoltage signal during power loss

  
  ∗ :The Momentary Power Loss Recovery Unit option may be required depending on the capacity of the drive.
