General purpose applications require everything in the same Drive. The CFW700 covers power levels from 1.1 to 132kW (1.5 to 150 HP).
One of the main focus for WEG Drives is have a robust product for general purpose applications. The CFW700 is a hight performance product with torque and speed control.
In applications where high inertia and short deceleration times are involved, a large amount of energy is returned from the motor to the VSD. To handle this energy traditional VSDs have to dissipate it as heat in power resistors, such resistors are usually large and very expensive also the heat dissipation has to be taken into consideration during installation.
As an alternative to the use of braking resistors the CFW700 features a special braking method in vector control mode named Optimal Braking®. This innovation delivers rated torque with high performance requiring no resistor. The graph illustrated shows a comparison of the braking torque offered by the different braking methods used.
The keypad can be remote assembled by using this configuration, degree of protection IP56 can be achieved.
The new CFW700 incorporates PLC functionalities by means of a factory built micro PLC named SoftPLC. This extra tool gives more flexibility to the product as well as allowing the user to develop his own application through a USB or RS485 ports port available at the control terminal.
