MV1000 Drive

Specifications & Features

Feature Highlights

  • Compact design which produces a very competitive footprint across the entire power range in a NEMA Type 1 enclosure (filtered and gasketed)
  • Using the Yaskawa Smart Harmonics™ Technology ensuring very low THD, without the need for additional filters
  • Unique output stage using an enhanced Cascaded H-Bridge configuration reduces the number of power cells by half, providing a very clean output waveform to the motor, without the need for additional filters or reactors
  • Advanced control features providing high performance including Open Loop Vector Control and excellent Energy Saving capabilities
  • Digital Operator with an easy-to-view LCD display (same as used on the A1000 series LV drives)
  • Communication options for all major industrial networks provides high speed control and monitoring, reducing installation cost
  • DriveWizard™ plus MV computer software and Application Sets for easy configuration
  • USB Copy Unit and Keypad configuration storage provide speed and convenience for duplicate configuration of multiple drives
  • High quality design, with an expected field MTBF greater than 200,000 Hours (22.8 years).
