2 GENERAL INFORMATION
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 CFW501.
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 CFW501, as well as WEG cannot take any liability for
the use of the CFW501 which is not based on this manual.
Part of the figures and tables are available in the appendixes, which are divided into

2.2 ABOUT THE CFW501
The frequency inverter CFW501 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 CFW501 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 CFW501.
