F03
Maximum Frequency
Sets the maximum frequency to drive the motor. Setting the frequency out of the
range rated for the equipment driven by the inverter may cause damage or a dan-
gerous situation. Set a maximum frequency appropriate for the equipment. For
high-speed motors, it is recommended that the carrier frequency be set to 15 kHz.
The inverter can easily set high-speed operation. When changing the speed setting,
carefully check the specifications of motors or equipment beforehand.
Otherwise injuries could occur.

Base Frequency
F05
Rated Voltage (at Base Frequency)
H50
Non-linear V/f Pattern (Frequency)
H51
Non-linear V/f Pattern (Voltage)
These function codes set the base frequency and the voltage at the base frequency
essentially required for running the motor properly. If combined with the related
function codes H50 and H51, these function codes may set data needed to drive the
motor along the non-linear V/f pattern.
The following description includes setting-up required for the non-linear V/f pattern.
Base frequency (F04)
Set the rated frequency printed on the nameplate located on the motor.
Rated voltage (at base frequency) (F05)
Set 0 or the rated voltage printed on the nameplate labeled on the motor.
- If 0 is set, the inverter supplies voltage equivalent to that of the power source of
the inverter at the base frequency. In this case, the output voltage will vary in line
with any variance in input voltage.
- If the data is set to anything other than 0, the inverter automatically keeps the
output voltage constant in line with the setting. When any of the automatic torque
boost settings, automatic energy saving or slip compensation is active, the volt-
age settings should be equal to the rating of the motor.
If F05 is set to match the rated voltage of the motor, motor efficiency will
be better than that it is set to 0. Therefore, when brakes are applied to the
motor, energy loss decreases and the motor regenerates larger braking
energy, which can easily cause the overvoltage protection function (
where n=1 to 3) to be activated. Note that the allowable power consump-
tion capacity of the inverter for braking energy is limited by the specifica-
tions. If the overvoltage protection function is activated, it may be nec-
essary to increase deceleration time or use an external braking resistor.
Non-linear V/f pattern for frequency (H50)
Sets the non-linear V/f pattern for frequency component.
(Setting 0.0 to H50 disables the non-linear V/f pattern operation.)
