The carrier freq. mainly affects the noise of motor and heat loss. The relationship between
carrier freq. and motor noise, leakage current, and interference shown as follow.

Note
：
(1) In order to get better control characteristic, the ratio of carrier frequency to inverter
highest running frequency is suggested beyond 36.
(2) Difference may occur in current value display, when carrier freq. is low.
