2.1 ABOUT THE MANUAL
This manual contains information for the proper installation and operation of the inverter, as well
as start-up procedures, main technical features and how to identify the most usual problems
of the different models of inverters of the line CFW500.
ATTENTION!
The operation of this equipment requires detailed installation and operation
instructions provided in the user's manual, programming manual and
communication manuals. The user's manual and the quick reference of the
parameters are supplied at the purchase of the inverter, while the guides are
supplied with their respective accessories. Other manuals are supplied in
CD-ROM only, which comes with the inverter or can be downloaded in WEG's
website - www.weg.net. This CD must be always kept with this equipment.
A printed copy of the files available in the CD can be requested at your local
WEG dealer.
NOTE!
It is not the intention of this manual to present all the possibilities for the
application of the CFW500, as well as WEG cannot take any liability for the use
of the CFW500 which is not based on this manual.
Part of the figures and tables are available in the appendixes, which are divided into

The information is presented in three languages.
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.
