Setting range: 0.00Hz/s – P00.03 (the max.
frequency)
After the power loss of the grid, the bus voltage
drops to the sudden frequency-decreasing point,
the VFD begin to decrease the running
frequency at P11.02, to make the VFD generate
power again. The returning power can maintain
the bus voltage to ensure a rated running of the
VFD until the recovery of power.

Note: 1. Adjust the parameter properly to avoid
the stopping caused by VFD protection during
the switching of the grid.
