Reduce Motor Noise or Leakage Current
Carrier frequency C6-02
If the wiring between the inverter and the motor is
excessively long, the inverter output current will be
increased because of the increased leakage current of
harmonics from the cable, which may affect the peripheral
devices.
Refer to the following table to adjust the inverter output
transistor switching frequency (carrier frequency).
Reducing such carrier frequency is effective for reduction
of radio noise.

or below)
