60% ～ 85% 80%
★
This parameter is used to judge whether the grid voltage is the threshold for instantaneous
power failure. When the bus voltage is less than P1-25, the inverter will decelerate according
to the method set by P1-23 to maintain the bus voltage constant. 100% corresponds to the
voltage level of the inverter.

★
This parameter is used to judge whether the grid voltage returns to the normal threshold.
When the bus voltage is greater than P1-26, the inverter will no longer decelerate. When the
duration is greater than P1-27, the inverter will accelerate until it reaches the set frequency.
100% corresponds to the voltage level of the inverter.

★
This parameter is used for the time judgment of grid voltage recovery. When the grid voltage
is higher than P1-26, the timing starts, otherwise it is cleared to 0.

It takes effect only when P1-23=1 is selected for the instantaneous stop and non-stop mode.
It is used to adjust the deceleration speed and generally does not need to be modified.
