Weg CFW701 Drive

                                            Weg CFW701 Benefits  

  • Fire Mode - This function makes the drive inhibit its internal faults, making the motor run during adverse conditions without stopping the process.
  • Sleep / Wake-Up Mode - Prevents the operation of the motor at low speeds for a amount of time programmed. Wake up mode determines the itime thedrive is restarted.
  • Broken Belt - Monitors motor torque and prevents the drive from running with no load in case of a broken belt.
  • Energy Saving - Depending on the motor speed and load conditions, flux is reduced decreasing losses and therefore effciency is improved.
  • Filter Maintenance Alarm - Warns about the need to replace the filter.
  • Bypass - Using one of its relay outputs the CFW701 allows the motor to be started cross the line. External circuit is needed for this operation.
  • Dry Pump - Prevents the pump from running with no load.
  • PTC - For monitoring PTC sensor
  • Short cycle Protection - Prevents a compressor / motor from being switched on and off in short periods of time.
  • Advanced PID -3 x PID - Three PID control loops: one controls the process by itself (the one the motor is running) and two are additional PID loops for use to control independent process variable.
