5-24
Base Frequency 1 (F04)
Set the rated frequency printed on the nameplate labeled 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 rated voltage at base frequency is determined by the power source of the
inverter. 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 auto torque boost settings, auto
energy saving or slip compensation is active, the voltage settings should be equal to the
rated voltage of the motor.
Non-linear V/f Patterns 1 and 2 for Frequency (H50 and H52)
Set the frequency component at an arbitrary point of the non-linear V/f pattern.
(Setting "0.0" to H50 or H52 disables the non-linear V/f pattern operation.)
Non-linear V/f Patterns 1 and 2 for Voltage (H51 and H53)
Sets the voltage component at an arbitrary point of the non-linear V/f pattern.
Maximum Output Voltage (F06)
Set the voltage for the maximum frequency 1 (F03).
• If F05 (Rated Voltage at Base Frequency 1) is set to "0," settings of H50 through
H53 and F06 do not take effect. (When the non-linear point is below the base
frequency, the linear V/f pattern applies; when it is above, the output voltage is
kept constant.)
• When the auto torque boost (F37) is enabled, the non-linear V/f pattern takes no
effect.
