Setting Description
Specifies the LVRT/HVRT recovery
threshold.
Specifies whether to shield the
undervoltage protection function
during LVRT or HVRT.
Specifies the percentage of the
maximum active current to the
rated current during fault ride-
through (FRT).
Specifies the recovery rate when
the active current recovers to the
value at the moment before FRT.
Certain countries and regions
have requirements on the output
current during high/low voltage
ride-through. In this case, set this
parameter to Enable. After this
parameter is set to Enable, the
output current is less than 10% of
the rated current during high/low
voltage ride-through.
If this parameter is set to Enable,
the inverter shuts down after
receiving the 0% power limit
command. If this parameter is set
to Disable, the inverter does not
shut down after receiving the 0%
power limit command.
If this parameter is set to Enable,
the active power of the inverter
will be derated according to a
certain slope when the grid
frequency exceeds the frequency
that triggers overfrequency
derating.

Remarks
● This parameter is displayed
when LVRT or HVRT is set
to Enable.
● LVRT recovery threshold =
LVRT triggering threshold +
VRT exit hysteresis
threshold
● HVRT recovery threshold =
HVRT triggering threshold -
VRT exit hysteresis
threshold
This parameter is displayed
when LVRT or HVRT is set to
