Base frequency
Base frequency and motor voltage
AVR function
(1) Base frequency and motor voltage
On selection of base frequency and motor voltage, set the output of the inverter (frequency voltage) to the
motor rating.
The Base frequency is the nominal frequency of the motor, this value can be found on the nameplate of the
motor. It is important to match the Base frequency (A003) to this nominal value or there is risk of damage to
the motor.
If a motor has a base frequency higher than 60Hz, it is considered to be a special motor. In this situation, it
is important to make sure the maximum output current of the inverter is higher than the FLC of the motor.
The Motor Voltage Selection is the nominal voltage of the motor, this value can be found on the nameplate of
the motor. It is important to match the Motor Voltage (A082) to this nominal value or there is risk of damage
to the motor.
When changing second base frequency (A203) / third base frequency(A303) an intelligent input terminal
must be set to 08(SET) / 17(SET3) and switched on.

(2) AVR function
Even if the incoming voltage changes, this function will keep the output voltage and a constant voltage level.
The output voltage to the motor in this function references to the voltage selected on motor voltage selection.
Select Yes/No of this function on A081 AVR selection.
