P0178 – Rated Flux
Adjustable
Range:
0.0 to 150.0 %
Factory
Setting:
100.0 %
Properties:
Access Groups
via HMI:
MOTOR
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 P0178 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.
NOTE!
Exclusively in the scalar control mode, parameter P0178 allows the adjustment of the output voltage
after defining the V/f curve. That could be useful for output voltage compensation or field weakening.
P0399 – Motor Rated Efficiency
Adjustable
Range:
50.0 to 99.9 % Factory
Setting:
75.0 %
Properties:
cfg, V VW
Access Groups
via HMI:
MOTOR, STARTUP
Description:
This parameter is important for the precise operation of the V VW control. A misconfiguration will cause incorrect
calculation of the slip compensation, reducing the performance of the speed control.
P0400 – Motor Rated Voltage
Adjustable
Range:
200 to 600 V
Factory
Setting:
According to
Table 10.2 on
page 10-6
Properties: cfg, V VW
Access Groups
via HMI:
MOTOR, STARTUP
Description:
Set according to the data on the motor nameplate and the wire connection on the motor terminal box. This
value cannot be above the rated voltage value set in P0296 (power supply rated voltage).
NOTE!
In order to validate a new setting of P0400 out of the HMI “STARTUP” menu, it's necessary to
de-energize/energize the inverter.
