8.4 Switching the carrier frequency

If the cable between the inverter and motor is long, the leak current from the cable
will increase. To reduce the leak current, lower the carrier frequency from the
default setting of 15 kHz to 10 kHz. (Note, however, that doing so will increase the
buzzing sound from the motor.)
Set DIP switch S4 (SW1) on the rear of the inverter to ON.
Factory setting: OFF (15 kHz)
