• For LD-mode inverters, set the maximum frequency at 120 Hz or below.
• Under vector control with speed sensor, set the maximum frequency at 200 Hz or below, and
under vector control without speed sensor, at 120 Hz or below.
The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the
specifications of motors or equipment beforehand.
Otherwise injuries could occur.
Modifying F03 data to allow a higher reference frequency requires also changing F15 data
specifying a frequency limiter (high).
F04 to F06
H50 to H53，H65，H66
Base Frequency 1, Rated Voltage at Base Frequency 1, Maximum Output
Voltage 1
Non-linear V/f Pattern 1, 2 and 3 (Frequency and Voltage)
These function codes specify 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 through H53, H65 and H66,
these function codes may profile the non-linear V/f pattern by specifying increase or decrease in voltage at
any point on the V/f pattern.
The following description includes setups required for the non-linear V/f pattern.
At high frequencies, the motor impedance may increase, resulting in an insufficient output voltage and a
decrease in output torque. To prevent this problem, use F06 (Maximum Output Voltage 1) to increase the
voltage. Note, however, that the inverter cannot output voltage exceeding its input power voltage.
„ Base Frequency 1 (F04)
Set the rated frequency printed on the nameplate labeled on the motor.
„ Rated Voltage at Base Frequency 1 (F05)
Set "0" or the rated voltage printed on the nameplate labeled on the motor.
- If F05 = 0, the rated voltage at base frequency is determined by the power source of the inverter. The
output voltage will fluctuate in line with the input voltage fluctuation.
- If F05 = an arbitrary value other than 0, the inverter automatically keeps the output voltage constant in
line with the setting. When any of the auto torque boost, auto energy saving, etc. is enabled, the F05 data
should be equal to the rated voltage of the motor.
„ Non-linear V/f Patterns 1, 2 and 3 for Frequency (H50, H52 and H65)
Set the frequency component at an arbitrary point in the non-linear V/f pattern.
Setting "0.0" to H50, H52 or H65 disables the non-linear V/f pattern operation.
