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 MW500.
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 MW500, as well as WEG cannot take any liability for the use
of the MW500 which is not based on this manual.
2.2 ABOUT THE MW500
The MW500 is a high-performance, decentralized inverter with IP66 degree of protection dust
an water. The MW500 allows speed and torque control of three-phase induction motors. This
product features vector (V V W ) and scalar (V/f) control - both programmable according to your
application.
In the vector control mode (V V W ), the operation is optimized for the motor in use, providing 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 one motor is activated by a inverter
simultaneously (multimotor applications).
The MW500 can be mounted coupled to the motor or on the wall, depending on the application
requirements.
The MW500 inverter also provides PLC functions (Programmable Logic Controller) by means
of the SoftPLC (integrated) feature. For further details regarding the programming of those
functions on the MW500, refer to the SoftPLC user's manual of the MW500.
The main components of the MW500 are shown in the block diagram of
