Setting range: 0.00Hz/s–P00.03 (Max. output
frequency)
After the power loss of the grid, the bus voltage
drops to the sudden frequency decreasing point,
the VFD begins to decrease the running
frequency according to P11.02, to make the VFD
generate power again. The returned power can
maintain the bus voltage to ensure normal
running of the VFD until the recovery of power.
Note:
Adjust the parameter properly to prevent the
stop caused by VFD protection during the
switching of the grid.
Prohibit input phase loss protection to enable
this function.
