○
The above parameter is used to select whether to provide protection for Input or output phase failure.
Only the VD series inverter of G model with over 11kW can have input phase loss protection function.

○
This function means that when instant power failure or voltage suddenly drop, inverter output speed
will decrease and load feedback energy will compensate to drop of inverter DC bus voltage, in order
to keep inverter run and avoid under voltage error caused stopping.
P13.20 is used in selecting protection function in instantaneous power failure, P13.21 is used in
frequency reduction mode selection when an instantaneous power: 0 is frequency decrease
according to P13.22 frequency decrease rate. When bus voltage is low or instantaneous power failure
and P13.20=1, then inverter output frequency will judge and interfere inverter output frequency
according to P13.21 selection mode and P13.22 set value, will normal run until bus voltage recovery.
P13.25

○
To check if motor is short circuit to ground when inverter powered on, if selecting detection enabled,
inverter output terminal U, V, W has voltage output after powered on for a short period, it is used to
check if motor is short circuit to ground or not.
