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.
P8-27
Terminal jog priority
0
:
Invalid 1: Valid
Default
:
0
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 6-20 shows
a schematic of this function.
