10.1 VVW VECTOR CONTROL PARAMETERIZATION
The V VW control mode is selected by parameter P202, control mode selection, as described in Chapter 8
AVAILABLE MOTOR CONTROL TYPES on page 8-1 .
Opposite to the V/f scalar control, the V VW control requires a series of data from the motor nameplate and a
self-tuning for its proper operation. Besides, it is recommended that the driven motor match the inverter, that is,
the motor and inverter power be as close as possible.
Below are described the parameters to configure the V VW vector control setting. This data is easily obtained on
WEG standard motor nameplates, however in older motors or motors made by other manufacturers, the data
may not be readily available. In those cases, it is recommended first contact the motor manufacturer, measure or
calculate the desired parameter. As a last resort, the user always can make a relationship with
Table 10.1 on page
10-3 and use the equivalent or approximate WEG standard motor parameter.
NOTE!
The correct setting of the parameters directly contributes to the V VW control performance.

P178 - Rated Flux
Adjustable
Range:
50.0 to 150.0 % Factory
Setting:
100.0 %
Properties: V VW
Description:
It defines the desired flux in the motor air gap in percentage (%) of the rated flux. In general, it is not necessary
to modify the value of P178 of the standard value of 100 %. However, some specific situations may use values
slightly above to increase the torque, or below to reduce the energy consumption.
