Menu PAR Description UM Type FB BIT Def Min Max Acc Mod
21.7 2412 Vf frequency 1 Hz FLOAT CALCF 0.0 CALCF ERWZS V
Setting of an intermediate frequency value for the custom V/f characteristic curve.
Menu PAR Description UM Type FB BIT Def Min Max Acc Mod
21.8 2414 Vf voltage 0 V FLOAT CALCF 0.0 CALCF ERWZS V
Compensation of IR voltage drop at 0 Hz. This parameter must be increased in case of pure V/f control. The in-
crease depends on the size of the motor. Values that are too high could cause an overcurrent and motor saturation.

Quadratic
Set 0 ( Linear ) to obtain a linear V/f characteristic curve, on which the intermediate points are reset to a value
that is equal to half those of parameters 2406 and 2408 .
The Boost joins the curve automatically.

Hz
Set 1 ( Custom ) to obtain a customized V/f characteristic curve, in which the intermediate voltage and fre-
quency values are defined by parameters 2410 and 2412 , as is the point at which the Boost joins the charac-
teristic curve.

V
Set 2 ( Quadratic ) to obtain a quadratic V/f characteristic curve, useful for controlling pumps and fans, where
torque is proportional to the square of the speed. When this type of curve is selected, the median voltage
point is fixed at 0.25% of the maximum output voltage (par. 2406 ), and the median frequency point at 50% of
the basic frequency (par. 2408 ).
