2 GENERAL INFORMATION
2.1 ABOUT THE MANUAL
This manual exposes how to install, to start-up in V/f (scalar) mode, the main characteristics and shows how to
troubleshoot the most common problems of the CFW-11M G2 inverter series.
It is also possible to operate the CFW-11M G2 in the following control modes VVW, Sensorless Vector and Vector
with Encoder. For further details on the inverter operation with other control modes, refer to the programming manual.
ATTENTION!
The operation of this equipment requires installation instructions and detailed operation provided
in the user manual, programming manual and manuals/guides for kits and accessories. The user's
manual and the parameters quick reference are supplied in a hard copy together with the inverter. The
user guides are also provided in a hard copy along with the kit/accessories. The other manuals are
available at www.weg.net. A printed copy of the files available on WEG’s website can be requested
at your local WEG dealer.

2.2 TERMS AND DEFINITIONS USED IN THE MANUAL
Normal Duty (ND): the duty cycle that defines the steady state current value I
nom
-ND and an overload of 110 % during
1 minute. It is selected by programming P0298 (Application) = 0 (Normal Duty (ND)). It must be used for driving
motors that are not subject in that application to high torques with respect to their rated torque, when operating
at constant speed, during start, acceleration or deceleration.
I
nom-ND
: corrente nominal do inversor para uso com regime de sobrecarga normal (ND = Normal Duty).
Overload: 1.1 x I
nom-ND
/ 1 minute.
Heavy Duty (HD): the duty cycle that defines the steady state current value I
nom
-HD and an overload of 150 %
during 1 minute. It is selected by programming P0298 (Application) = 1 (Heavy Duty (HD)). It must be used for
driving motors that are subject in that application to high torques with respect to their rated torque, when operating
at constant speed, during start, acceleration or deceleration.
I
nom-HD
: inverter rated current for use with heavy duty cycle (HD = Heavy Duty).
Overload: 1.5 x I
