Changingthe switching frequency can help to reduceacoustic noise from the motor.14-01 Switching FrequencyOption: Function:NOTICEThe output frequency value of thefrequency converter must never exceed1/10 of the switching frequency. When themotor is running, adjust the switchingfrequency in parameter 14-01 SwitchingFrequency until the motor is as noiseless aspossible.
