Advantages of applying variable speed drives for pumps:

  • Start, stop and control the rotation frequency of pump’s motor.
  • Acceleration and braking with assigned rates.
  • Reversal.
  • Acceleration, decreasing, stop.
  • Protection of the motor against overcurrent, overload protection.
  • Motor control by external 2-wire and 3-wire sensors.
  • Saving control configuration of motor.
  • Control five motors at the same time (Cascade controller - macros).
  • Control five motors at the same time (Cascade controller - macros)
  • Automatic control of technology processes by closed-loop system principle using built-in PID-controller.
  • Automatically restart asynchronous motor after supply voltage failure or after special emergencies of motor (customized emergencies)
  • Operation of asynchronous motor by custom preset diagram in automatic or manual mode.
