8.14 Skip frequency
By setting the jump frequency, the inverter can avoid the mechanical resonance point of the load. NVF2G-S
-S can set three hopping frequency points, if all hopping frequencies are set to 0, the hopping frequency
function will be cancelled.
8.15 Forward and reverse switching
In some occasions, it needs to delay for a period of time when switching between forward and reverse
rotation of the motor. At this time, the dead time of forward and reverse rotation can meet the demand.
