Setting:
75.0 %
Properties: cfg, V V W
Access groups
via HMI:
MOTOR, STARTUP
Description:
This parameter is important for the precise operation of the VVW control. The imprecise setting will cause the

P0400 – Motor Rated Voltage
Adjustable
Range:
200 to 600 V Factory
Setting:
According to Table
10.2: Default setting
of P0400 according
to the identified
inverter model on
page 10-5
Properties: cfg
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 power
cycle the inverter.
