CFW-11 PRODUCT INFORMATION

  • Applications involving high inertia loads, when applied short time deceleration, a large amount of energy returns from the motor to the VSD. To handle this energy, reguilar VSDs have to dissipate it as heat in power resistors. Such resistors are usually large and some installation criteria must be considered due to their heat dissipation. As an alternative to the use of braking resistors, CFW11 features a special braking method in vector control mode known as Optimal Braking®. This innovation delivers a high performance braking torque without requiring a braking resistor. The following graph shows the advantages of using Optimal Braking® compared to other braking methods, thus ensuring an optimized and low cost solution for braking applications.

  • Linear and adjustable V/F, VVW (Voltage Vector WEG) and vector control are available on CFW11
  • Two types of vector control: sensorless and closed loop vector control (encoder Interface required)
  • Sensorless vector control permits high torque and quick response in open loop, even at low speeds
  • The self-tuning function sets the vector control or VVW with the motor and to application load used
  • By the adjustable V/F control, it is possible, for example, to adjust a quadratic V/F curve, providing energy savings for quadratic torque loads (e.g.: centrifugal pumps and fans)
