General Information
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. In such cases it is possible to reduce the losses in the motor and the inverter
using the "V/f Quadratic", which results in energy savings. The V/f mode is used when more than
a motor is activated by an inverter simultaneously (multimotor applications).
The main components of the CFW100 can be viewed in the block diagram of Figure 2.1 on
page 11.
