4.6.3 Second Menu V/Hz Parameter Descriptions (H.000 to H.022)
Base frequency is the frequency at which the output voltage reaches Motor
Nameplate Voltage (H.000). Below base frequency, the output voltage varies with
output frequency according to the V/Hz adjustment in parameter H.018 (Volts/Hertz
Curve Type). Above base frequency, output voltage is held constant as frequency
increases (constant horsepower range).
The V/Hz ratio is affected by the selection of Volts/Hertz Curve Type in H.018 and the
setting of Torque Boost Voltage in H.003. See figure 4.10.
H.000 Motor Nameplate Volts
This parameter
identifies the motor
nominal voltage as it
appears on the motor
nameplate. Parameter Range: 100 VAC to 690 VAC
Default Setting: 460 VAC
Parameter Type: Configurable

H.001 Motor Nameplate Base Frequency
This parameter
configures the V/Hz
ratio. Parameter Range: 30.0 to 200.0 Hz
Default Setting: 60.0 Hz
