The oscillation suppression is for VF control, the current oscillation phenomena often
occurs when the ordinary motor runs with light load or no load, which can cause
abnormal operation of motor or even the overcurrent of inverter. When Fb.07 = 0, the
oscillation suppression will be enabled;the inverter will suppress the oscillation of
motor according to the parameters of Fb.03 to Fb.06 function group.

PWM mode 1: V/F control is less than 8Hz as the seven-stage type, greater than 12Hz
as the five-stage type.
PWM mode 2: V/F control fully uses the seven-stage type.
PWM mode 3: V/F control fully uses the five-stage type.

When the motor runs at constant speed with no load or light load, the inverter detects
the load current, adjusts the output voltage, in order to automatically save energy.
