5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
Base frequency (F04)
Set the data in accordance with rated frequency of the motor (given on the nameplate of the motor).
• Data setting range 5.0 to 599.0 (Hz)
Rated voltage at base frequency (F05)
Set the data to “0” in accordance with rated voltage of the motor (given on the nameplate of the motor).
• Data setting range: 0 : AVR disable
80 to 240 (V) : AVR operation (at 200 V series)
160 to 500 (V) : AVR operation (at 400V series)
• When data is set to “0”, the base frequency voltage becomes equivalent to inverter input voltage. When input
voltage fluctuates, output voltage fluctuates as well (no AVR operation).
• When data is set to arbitrary voltage other than “0”, automatically keeps the output voltage constant (AVR
operation). When control function such as auto torque boost, auto energy-saving operation, and slip
compensation is used, it is necessary to adjust to the rated voltage (given on the nameplate of the motor) of the
motor.
• By turning ON digital input AVR cancel “AVR-CCL” (E01 to E09 = 116)”, AVR is canceled, and the same operation
as F05 = 0 is performed.
The voltage that the inverter can output is lower than the input voltage of the inverter. Appropriately set
the voltage in accordance with the motor.
With vector control, current feedback control is performed. Current feedback control is used to control the
current based on the difference between the motor induced voltage and the inverter output voltage.
Consequently, if the inverter output voltage is not set to ensure that a higher voltage than the motor
induced voltage is output, it will not be possible to perform control correctly. Generally speaking, the
voltage difference is 20 V for the 200V series, and 40 V for the 400V series. The voltage that the inverter
can output is equivalent to the input voltage of the inverter. Set the voltage appropriately based on the
motor. When using a dedicated Fuji motor for vector control (VG motor), by setting VG motor (capacity:
P02, motor type: P99), F04 and F05 are set automatically. If using a general-purpose motor to perform
speed sensorless vector control, set the rated voltage for base frequency voltage 1 (F05). The above
voltage difference is set with an induced voltage coefficient for vector control (P56). (Generally speaking,
the initial value may be used.)
Non-linear V/f 1, 2, 3 (Frequency) (H50, H52, H65)
Set frequency at the arbitrary point of non-linear V/f pattern.
• Data setting range: 0.0 (Cancel), 0.1 to 599.00 (Hz)
When 0.0 is set, the setting becomes the pattern without using non-linear V/f pattern.
Non-linear V/f 1, 2, 3 (Voltage) (H51, H53, H66)
Set voltage at the arbitrary point of non-linear V/f pattern.
• Data setting range: 0 to 240 (V) : AVR operation (at 200V series)
0 to 500 (V) : AVR operation (at 400V series)
Maximum output voltage 1 (F06)
Set the voltage at maximum output frequency 1 (F03).
• Data setting range: 80 to 240 (V) : AVR operation (at 200V series)
160 to 500 (V) : AVR operation (at 400V series)
When rated voltage at base frequency (F05) is “0”, the data of non-linear V/f (H50 to H53, H65, and H66)
and F06 becomes invalid (linear V/f for at or below base frequency, and constant voltage for at or higher
than base frequency).
