Base Frequency and Maximum Frequency of Motor

To configure the V/f control characteristics output to the motor, set the base frequency and maximum
frequency of your motor.
For the base frequency, set the rated frequency of the motor (the frequency listed on the motor rating
nameplate).
For the maximum frequency, set the highest frequency required for your application. However, do not
exceed the maximum rotation speed of the motor.
Then, set the 1st/2nd Motor Rated Voltage Selection (A082/A282) to the rated voltage of the motor.

Precautions for Correct Use
• Motors whose rated frequency exceed 60 Hz are regarded as special motors.
For these motors, check the rated motor current and select an appropriate inverter based on
the rated current of the inverter.
If you must use the motor at higher than 400 Hz, use the high-frequency mode.
• Do not set the base frequency to lower than the motor rated frequency. Doing so may cause
overload or motor burnout.
• Do not set the motor rated voltage to the motor rated frequency or higher. Doing so may
cause an overload or motor burnout.
