    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.

    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.

    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.

    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.
