Set the Motor Base Frequency - The motor is designed to operate at a specific AC
frequency. Most commercial motors are designed for 50/60 Hz operation. First, check
the motor specifications. Then follow the steps below to verify the setting or correct it
for your motor. DO NOT set it greater than 50/60 Hz unless the motor manufacturer
specifically approves operation at the higher frequency.

for your motor. DO NOT set it greater than 50/60 Hz unless the motor manufacturer
specifically approves operation at the higher frequency.
CAUTION: If you operate a motor at a frequency higher than the inverter standard
default setting (50Hz/60Hz), be sure to check the motor and machine specifications with
the respective manufacturer. Only operate the motor at elevated frequencies after getting
their approval. Otherwise, there is the danger of equipment damage.

Set the AVR Voltage Setting - The inverter has an Automatic Voltage Regulation (AVR)
function. It adjusts the output voltage to match the motor’s nameplate voltage rating. The
AVR smooths out fluctuations in the input power source, but note that it does not boost
the voltage in the event of a brown-out. Use the AVR setting (A082) that most closely
matches the one for your motor.
