7.5.17 V/f gain setting [A045/A245]
The V/f gain setting function allows you to change the inverter output voltage by specifying the rate of the
output voltage to the voltage (100%) selected with the AVR voltage select function (A082).
If the motor operation is cranky, try to decrease the gain setting.
