Flow Control Applications
Fans, Pumps, and Compressors
  • Improved energy efficiency during periods of low demand
  • PID functionality makes advanced control easy and efficient without the need of an external controller
  • Easily avoid equipment resonant frequencies and reduce high vibration levels using the skip frequency
  • Catch an already spinning motor to reduce start-up time and increase productivity
  • Motor thermal protection prevents overheating of the motor during operation
  • Fire mode maximises availability of a building's smoke extraction system in the event of a fire. Once activated the drive will run until failure
Moving applications
Conveyors, Treadmills, Automatic Doors & Barriers
  • Reliable speed control with onboard communications
  • S-ramp acceleration / deceleration profiling provides smooth speed transitions minimising machine jerk
  • Linear V to F with a controllable boost to get the machine running
  • Drive overload capacity up to 150% for rapid acceleration or load changes
  • DC braking with stop indication used to stop the motor quickly
Processing applications
Mixers, Crushers, Agitators, Centrifuges, Kneaders, Spinning & Braiding Machines for Textiles
  • Ease of integration to external PLC or other management systems with on board communications 
  • Stability optimiser for improved motor control
  • Resistance compensation for excellent torque performance
  • Built-in EMC filter effectively reduces electromagnetic interference
