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 6-21 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; if the running frequency is greater than
P8-25, the acceleration time 1 is selected.
During deceleration, if the running frequency is greater than P8-26, the
deceleration time 1 is selected. If the running frequency is less than P8-26,
the deceleration time 2 is selected.
This parameter is used to set whether the terminal jog function has the
highest priority.
When the terminal jog priority is valid, if the terminal jog command
appears during operation, the inverter switches to the terminal jog operation
state.

When the output frequency of the inverter is within the positive and
negative detection range of any arrival frequency detection value, the ON
signal is output. Figure 6-22 shows a schematic of this function.
