MOTOR CONTROL
P178 - Rated Flux
Range:
Properties:
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 100,0 %. However, some specific situations may use values
slightly above to increase the torque, or below to reduce the energy consumption.
P399 - Motor Rated Efficiency
Range:
Properties:
Description:
This parameter is important for the precise operation of the VVW control. A misconfiguration will cause incorrect
calculation of the slip compensation, reducing the performance of the speed control.
P400 - Motor Rated Voltage
Range:
Properties:
Description:
Set according to the data on the motor nameplate and the wire connection on the motor terminal box. Default
values are shown in the
8 (power supply rated voltage).
For further information on model identification, refer to
IDENTIFICATION on page
P401 - Motor Rated Current
Range:
Properties:
Description:
It defines the rated motor current. Parameter P401 must be set according to the information on the motor
nameplate, taking into account the motor voltage.
