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.
