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.

Questions and answers
Start stop time
The start-stop time for the INVT Goodrive20-EU VFD Series is not explicitly mentioned in the provided context. However, the "Pre-exciting time" (P03.25) is listed as a parameter that helps improve torque performance during startup, with a setting range of 0.000 to 10.000 seconds. If more specific start-stop time details are needed, they may be found in additional documentation.
