Description

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.

Applications

Its vast range of functions, easy configuration, installation and operation, in addition to the versions for electrical and modular panel mounting, make the CFW11 suitable for applications in different sectors of the industry:

• Pumps and fans
• Compressors
• Multipump control
