Leading Technology

  • Multi-pulse input rectification reduces input current harmonic distortion, meeting IEEE 519-1992
  • Advanced drive concept provides multilevel output voltages and enhanced motor operation
  • Enhanced input power quality ensures input power factor above 96% in the speed control range

Protection Features

  • Over-current
  • Overload
  • Under/Over voltage
  • Transformer over-temperature
  • Low system voltage
  • Motor protection via external signals
  • Drive over temperature
  • Cooling fan abnormal
  • Cabinet door open alarm
  • Internal cabinet pressure monitoring
  • Output short circuit
  • Input / Output Phase loss
  • Phase-to-ground fault
  • Communication error

Enhanced Process & Quality Control

  • Built-in proportional integral differential (PID) controller enhances control of proces variables such as flow and pressure
  • Ride through and flying start features ensure a more continuous process in spite of input voltage dips
  • Easily integrated with customer’s upper level control

Control & Monitoring Features

  • Frequency reference (Hz)
  • Actual frequency (Hz)
  • Input / Output power / current / voltage
  • Operation hours
  • Drive status
  • Status of system bypass switches and MCB
  • Analogue inputs / outputs monitoring
  • Fault / Alarm messages
  • Fault diagnosis function
  • Ride-through and flying start functions

Lower Cost of Ownership

  • Reduced power loss maintains overall efficiency above 96.5% (including transformer) and minimizes operating costs over the drive’s life cycle
  • Optimized pump and fan operation ensures significant energy savings and shortens the return on investment
  • Integrated transformer enables a three-cables-in-three-cablesout installation concept using considerably less engineering effort
  • Reduced mechanical stresses eliminates hammer effect in pipelines, and lowers maintenance cost
  • Multilevel voltages, controlled current start-up, and smooth response to load step minimize motor stresses
