This function is effective when the acceleration/deceleration time is not selected by
switching the input terminal. It is used to select different acceleration/deceleration time
according to the operating frequency range without passing through the input terminal
during the running of the inverter.

Figure 6-19 shows the switching of acceleration/deceleration time. During the acceleration
process, if the running frequency is less than P8-25, the acceleration time 2 is selected;
