Setting of the motor rated frequency (indicated on the motor data plate)
This is the frequency at which the drive output voltage reaches the maximum output voltage (Vfvoltage) on the mo-
tor.

21.8 2414 Vfvoltage0 V FLOAT 0.0 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 increase
depends on the size of the motor. Values that are too high could cause an overcurrent and motor saturation.

0 Linear
1 Custom
2 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.

Set 1 (Custom) to obtain a customized V/f characteristic curve, in which the intermediate voltage and frequency
values are dened by parameters 2410 and 2412, as is the point at which the Boost joins the characteristic curve.
