V/Hz Regulation Mode Parameters

H.000

Motor Nameplate Voltage

Parameter Range: 180 VAC - 690 VAC
Initial Setting: 380 VAC
Type: Configurable (at standby only)
Description: Motor nominal voltage as read from the motor name plate.
After any change of value in H.000 activate the 'Identification' procedure H.020.
Note: The display doesn't show above entered value at no-load operation due to the
automatic voltage boost function !
Under no-load the display-mode (volts) can show lower values, because automatic
torque boost is not effective at low currents.
H.001

Base Nameplate Frequency (V/Hz)

Parameter Range: 30.0 Hz - 200.0 Hz
Initial Setting: 50.0 Hz
Type: Configurable (at standby only)
Refer to: H.003 Torque Boost Voltage
H.018 Volts/Hertz Curve Mode
Description: This parameter configures the V/Hz ratio.
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
parameter H.018 (Volts/Hertz Curve Mode).
Above base frequency, output voltage is
held
(constant horsepower range).
The V/Hz ratio is affected by the selection of
Volts/Hertz Curve Mode in H.018 and the
setting of Torque Boost Voltage in H.003.
H.002

Motor Nameplate Amps

Parameter Range: Power module-dependent
Initial Setting: Power module-dependent, see instruction manual 'GV3000 Power Units'
49'1327.
Type: Configurable (at standby only)
Refer to: P.005 Current Limit
Description: This parameter is the motor amp rating as it appears on the motor nameplate.
CAUTION: This parameter must not exceed the rated amps found on the motor
nameplate. Excess heating of the motor could result if this is not done. Failure to
observe this precaution could result in damage to, or destruction of the equipment.
