2.2 ABOUT THE CFW500

The frequency inverter CFW500 is a high-performance product which allows the speed and
torque control of three-phase induction motors. This product provides the user with the options
of vector (V V W ) or scalar (V/f) control, both programmable according to the application.
In the vector mode (V V W ), the operation is optimized for the motor in use, obtaining a better
performance in terms of speed regulation.
The scalar mode (V/f) is recommended for simpler applications, such as the activation of most
pumps and fans. The V/f mode is used when more than a motor is activated by an inverter
simultaneously (multimotor applications).
The frequency inverter CFW500 also has functions of PLC (Programmable Logic Controller)
by means of the SoftPLC (integrated) feature. For further details regarding the programming of
those functions, refer to the SoftPLC user's manual of the CFW500.
