Output frequency (Fout) decreases to the lower limit frequency (00-13) and the Fout time is over than
the duration of lower limit frequency (24-04). Then Relay 4 is power off and the inverter accelerates
to the upper limit frequency (00-12).
When Fout reaches to the upper limit frequency (00-12), the inverter starts to decelerate.
