Rated voltage at base frequency (F05)
Set "0" or the rated voltage printed on the nameplate labeled on the motor.
➢
If "0" is set, the rated voltage at base frequency is determined by the power source of the inverter. The
output voltage will vary in line with any variance in input voltage.
➢
If the data is set to anything other than "0," the inverter automatically keeps the output voltage constant in
line with the setting. When slip compensation function is active, the voltage settings should be equal to the
rated voltage of the motor.
-
Maximum Output Voltage (F06)
Set the voltage for the maximum frequency 1 (F03).
➢
If F05 (Rated Voltage at Base Frequency 1) is set to "0," settings of F06 do not take effect.

Torque boost setting
F32 specifies V/f pattern, torque boost type for optimizing the operation in accordance with the characteristics
of the load. F30 specifies the type of torque boost in order to provide sufficient starting torque.
