P0178 – Rated Flux
Adjustable
Range:
0 to 120 %
Factory
Setting:
100 %
P0179 – Maximum Flux
Adjustable
Range:
0 to 120 %
Factory
Setting:
120 %
Properties: Vector
Access groups
via HMI:
Description:
The parameter P0178 is the flux reference, while the parameter P0179 defines the maximum value for the flux
(magnetization) current.
NOTE!
These parameters must not be modified.
P0190 – Maximum Output Voltage
Adjustable
Range:
0 to 480 V Factory
Setting:
0.95 x P0296.
Automatic
setting during
the Oriented
Start-up Routine:
0.95xP0400.
Properties:

Description:
This parameter defines the value of the maximum output voltage. Its standard value is defined in the condition
of the nominal supply voltage.
The voltage reference used in the regulator “Maximum output voltage” (see the illustration 11.1 or 11.2 ) is directly
proportional to the voltage supply.
If this voltage increases, the output voltage will then be able to increase to the adjusted value in the parameter
P0400 - Motor Rated Voltage.
If the voltage supply decreases, the maximum output voltage will decrease in the same proportion.
