2.1 ABOUT THE MANUAL

This manual contains information for the proper installation and operation of the inverter, commissioning, main
technical features and how to identify the most usual problems of the different models of inverters of the
CFW100 line.
ATTENTION!
The operation of this device requires detailed installation and operation instructions, which are provided
in the user's manual, programming manual and communication manuals. The guides are supplied
in print together with the respective accessory or can be downloaded on www.weg.net. You can
request a copy in print of the files from your local WEG representative.
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

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 (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.
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 CFW100 frequency inverter also has PLC (Programmable Logic Controller) functions by means of the SoftPLC
(integrated) tool. For further details regarding the programming of those functions, refer to the SoftPLC user's
manual of the CFW100.
