Easy to Use
The CFW11 has many useful and convenient functions for the customers, especially because of its simple installation and operation. The CFW11 has been designed based on the plug-and-play technology, which allows a simple and quick installation of the inverter and its accessories. The HMI has a navigation and programming system with soft keys. You can access the parameters sequentially or through parameter groups.
The HMI also offers the oriented start-up function that guides the user along the programming.
Flexibility
The CFW11 is adaptable to the customer’s needs through a wide range of easy-to-install accessories. In addition, the standard version comes with SoftPLC, allowing the customers to create their own applications using the WLP (Ladder Programming) software application.
Connectivity
Communication protocols: Modbus-RTU, Modbus-TCP, Profibus-DP-V1, DeviceNet, CANopen, EtherNet/IP, EtherCAT, PROFINET-IO and BACnet.
Vectrue Technology®
- 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)
Optimal Braking®
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, regular 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.
SoftPLC Function
It is a resource that provides PLC features to the CFW11 without the addition of any accessories. It provides flexibility to the product, allowing the user to create his/her own applicative software (user’s program).
