FU1-41 ~ FU1-48: User V/F Frequency and Voltage
□
□
□
These functions are available only when ‘User V/F’
is selected in FU1-40 [V/F pattern]. Users can make
the custom V/F pattern by setting four points between
FU1-32 [Starting Frequency] and FU1-31 [Base
Frequency].
[User V/F]
Note: When the ‘User V/F’ is selected, the torque
boost of FU1-67 through FU1-69 is ignored.
FU1-49: AC Input Voltage Adjustment
It should be set correctly when inverter input voltage
and standard input power rating is far different.
Otherwise, it will cause inverter damage. This set
value affects inverter LV trip (low voltage trip) level.
Used only when line fluctuation exceeds its
permissible range or input power far different to its
standard value is applied.

Note: As soon as FU1-49 value is set through a
button on the keypad, its set value is applied.
FU1-50: Motor Voltage
Constant voltage output is possible regardless of
input voltage fluctuation by setting this parameter.
☞ Caution: When input voltage is less than FU1-
50 [Motor rated voltage], Max output voltage
cannot exceed input voltage.
