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 CFW500.
ATTENTION!
The operation of this equipment requires detailed installation and operation
instructions provided in the user’s manual, programming manual and
communication manuals. These file are available on the WEG’s website -
www.weg.net. A printed copy of the files 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 APPENDIX
A - FIGURES on page 151 and APPENDIX B - TECHNICAL SPECIFICATIONS on page 157.
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 offers up to four options to control
the motor: V/f scalar control, VVW control, vector control with sensor and sensorless.
In the vector control, the operation is optimized for the used motor, providing a better performance
in terms of speed and torque control. The "Self-Tuning" function, available for the vector control,
allows the automatic setting of control parameters and controllers based on the identification
of the motor parameters.
The VVW control (Voltage Vector WEG) has a performance and precision between the V/f scalar
control and the vector control; on the other hand, it adds robustness and simplicity to drive
motors without speed sensors. The self-tuning function is also available in the VVW control.
The scalar control (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.
The main components of the CFW500 can be viewed in the block diagram Figure 2.1 on
page 5 for frame sizes A, B, and C, Figure 2.2 on page 6 for frame sizes D and E and
Figure 2.3 on page 7 for frame size F.
