at your local WEG dealer.
NOTE!
It is not the intention of this manual to present all the possibilities for the application
of the CFW100, as well as WEG cannot take any liability for the use of the CFW100
which is not based on this manual.
Part of the figures and tables are available in the annexes, which are divided into APPENDIX A -
FIGURES on page 119 for figures and APPENDIX B – TECHNICAL SPECIFICATIONS on page
121 for technical specifications.
For further information, refer to the programming manual.
2.2 ABOUT THE CFW100
The CFW100 frequency inverter is a high-performance product which allows speed and torque
control of three-phase induction motors. This product provides the user with the options of vector
(VVW) or scalar (V/f) control, both programmable according to the application.
Buy: www.ValinOnline.com | Phone [phone] | Email: [email protected]

General Information
English
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.
