You can select to exercise Soft-PWM control and

long wiring mode. When Soft-PWM

control is made valid, you can change the metallic tone of motor sound into an

unoffending complex tone. Surge voltage is surpressed in the long wiring mode

regardless of the wiring length between the inverter and motor. (When operating a
