H.000 Motor Nameplate Base Volts
This parameter
identifies the motor
nominal voltage as it
appears on the motor
nameplate. Parameter Range: 100 VAC to 345 VAC
Default Setting: 230 VAC
Parameter Type: Configurable
Refer also to parameters: N/A
H.001 Motor Nameplate Base Frequency
This parameter
configures the V/Hz
ratio. Parameter Range: 30.0 Hz to 200.0 Hz
Default Setting: 60.0 Hz
Parameter Type: Configurable
Refer also to parameters: H.003 Torque Boost Voltage
H.018 Volts/Hertz Curve Type
Base frequency is the frequency at which th
e 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.
