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, 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.

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).

The SoftPLC main features are:

Ladder language programming using WLP software
Access to all VSD parameters and I/Os
Configurable PLC, mathematical and control blocks
Applicative software download, upload and online monitoring via USB connection
Storage of user application in the CFW11 flash memory module (see below)
Memory capacity of 15 kB for user application storage

Flexibility is Our Philosophy

The CFW11 was developed based on Plug & Play philosophy, identifying automatically the accessories plugged in, as well as easy installation and safe operation with no need for extra configuration.

Remote Keypad

The keypad can be installed on panel doors or machine consoles with a IP56 protection degree.
