Chapter 4 - Parameter Description [FU1]
44
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
that has a lower rated voltage than the main input
voltage. When this is set at 100%, inverter outputs
its rated voltage.
☞
Note: Motor rated voltage should b e within the range of
inverter rated voltage. Otherwise, overcurrent trip may occur.
☞
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). 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.
[When Energy Save Level is set at 20%]
☞
Note: This function is not recommended for a large load or for
an application that need frequent acceleration and
deceleration.
