FU1-30 ~ FU1-37: User V/F Frequency and
Voltage
□
□
□
These functions are available only when ‘User V/F’ is
selected in FU1-29 [V/F pattern]. Users can make the
custom V/F pattern by setting four points between FU1-
22 [Starting Frequency] and FU1-21 [Base Frequency].
[User V/F]
☞ Note: When the ‘User V/F’ is selected, the torque boost
of FU1-26 through FU1-28 is ignored.
FU1-38: Output Voltage Adjustment
This function is used to adjust the output voltage of the
inverter. This is useful when using a motor with a lower
rated voltage than the main input voltage. When this is
set at 100%, inverter outputs its rated voltage.
☞ Note: The inverter output voltage does not
exceed the main input voltage, even though
FU1-38 is set at 110%.
FU1-39: Energy Save Level
This function is used to reduce the output voltage in
applications that do not require high torque and current
at its steady speed. The inverter reduces its output
voltage after accelerating to the reference frequency
(steady speed) if the energy save level is set at 20%.
This function may cause over-current trip due to the lack
of output torque in a fluctuating load.
This function does not work with 0% set point value.
