Pr.03, Pr.04, Pr.05, Pr.06, Pr.07, Pr.08, Pr.09 – V / F Curve
Pr.03 Maximum Output Frequency
Factory Setting d60.0 Hz
Units 0.1 Hz
Parameter value d50.0 - d400.0 Hz
This parameter determines the maximum AC drive output frequency. Analog inputs (0 -
10 V, 4 - 20 mA) are scaled to correspond to the output frequency range.
Pr.04 Motor Frequency
Factory Setting d60.0 Hz
Units 0.1 Hz
Parameter value d10.0 - d400.0 Hz
This value should be set according to rated frequency of the motor as indicated on the
motor nameplate.
Pr.05 Motor Voltage
Factory Setting d220.0
Units 0.1 V
Parameter value d2.0 - d255.0
This parameter determines the Maximum Output Voltage of the AC drive. The maximum
output voltage setting must be smaller than or equal to the rated voltage of the motor as
indicated on the motor nameplate.
Pr.06 Mid-point Frequency
Factory Setting d1.50 Hz
Units 0.1 Hz
Parameter value d0.1 - d400.0 Hz
This parameter sets the Midpoint Frequency of the V/F curve. It may be used to
determine the V/F ratio between the Minimum Frequency and the Mid-point Frequency.
Pr.07 Mid-point Voltage
Factory Setting d12.0 V
Units 0.1 V
Parameter value d2.0 - d255.0
This parameter sets the Midpoint Voltage of the V/F curve. It may be used to determine
the V/F ratio between the Minimum Voltage and the Mid-point Voltage.
