In vector control, current feedback control is performed. In the current feedback control, the current is
controlled with the difference between the motor induced voltage and the inverter output voltage. For a
proper control, the inverter output voltage should be sufficiently higher than the motor induced voltage.
Generally, the voltage difference is about 20 V for 230 V series, about 40 V for 460 V series.
The maximum voltage the inverter can output cannot exceed the inverter input voltage. Configure these
voltages correctly in accordance with the motor specifications.
When enabling the vector control without speed sensor using a general-purpose motor, set the F05
(Rated Voltage at Base Frequency 1) data at the rated voltage of the motor. The voltage difference
described above is specified by function code P56 (Induced voltage factor under vector control).
Generally, there is no need to modify the initial setting.

Non-linear V/f Patterns 1, 2 and 3 for Frequency (H50, H52 and H65)
Data setting range: 0.0 (cancel); 0.1 to 500.0 (Hz)
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.

Non-linear V/f Patterns 1, 2 and 3 for Voltage (H51, H53 and H66)
Data setting range: 0 to 240 (V): Output an AVR-controlled voltage for 230 V series
0 to 500 (V): Output an AVR-controlled voltage for 460 V series
Sets the voltage component at an arbitrary point in the non-linear V/f pattern.

Maximum Output Voltage 1 (F06)
Data setting range: 80 to 240 (V): Output an AVR-controlled voltage for 230 V series
160 to 500 (V): Output an AVR-controlled voltage for 460 V series
Set the voltage for the maximum frequency 1 (F03).
F07, F08 Acceleration Time 1, Deceleration Time 1
E10, E12, E14 (Acceleration Time 2, 3 and 4)
E11, E13, E15 (Deceleration Time 2, 3 and 4)
H07 (Acceleration/Deceleration Pattern)
H56 (Deceleration Time for Forced Stop)
H54, H55 (Acceleration Time/Deceleration Time, Jogging)
H57 to H60 (1st and 2nd S-curve Acceleration/Deceleration Range)
F07 specifies the acceleration time, the length of time the frequency increases from 0 Hz to the maximum
frequency. F08 specifies the deceleration time, the length of time the frequency decreases from the maximum
frequency down to 0 Hz.
- Data setting range: 0.00 to 6000 (s)
Under V/f control
If F05 (Rated Voltage at Base Frequency 1) is set to "0," settings of H50 through H53, H65, H66 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.)
