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.

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.
