Yaskawa A1000 Feature Highlights

  • Ratings: 3/4 to 1000 Hp at 460VAC ; 1/2 to 175 Hp at 230VAC
  • Closed or open loop vector control for outstanding regulation, torque production, and position control capability
  • Continuous Auto-tuning optimizes performance by compensating for changes in motor temperature
  • High Frequency Injection enables high precision open loop control of Interior Permanent Magnet Motors
  • Fast acting current and voltage limiters help achieve continuous drive operation during periods of excessive demand
  • High Slip Braking reduces installation cost and the need for dynamic braking resistors
  • Communication options for all major industrial networks provides high speed control and monitoring, reducing installation cost
  • DriveWizard computer software and Application Sets for easy configuration
  • Auxiliary Control Power Unit maximizes production time and efficiency by maintaining network communication while main power is removed
  • Embedded Safe Torque Off minimizes downtime for applications requiring occasional intervention (SIL CL2, PLd, Category 3)
  • Embedded function blocks, programmable with DriveWorks EZ, provide additional application flexibility and the opportunity to eliminate separate controllers
  • USB Copy Unit and Keypad configuration storage provide speed and convenience for duplicate configuration of multiple drives
  • Removable terminal board with configuration storage provides convenience of configuration backup
  • Made with RoHS compliant materials
  • Integrated DC Reactor (standard on 30HP and larger) for input harmonic reduction
  • Kinetic Energy Braking allows drive to remain in control during momentary power losses
