Fronius GEN24 Operating Instructions Manual page 30

Regions R1 to R3 must have descending values of detection thresholds:
-
-
-
To deactivate a specific region, its threshold can be used:
An HV region (R1) is deactivated by adjusting the threshold to 200 %. An LV re-
gion (R3) is deactivated by adjusting the threshold to 0 %.
General VFRT settings
The following setting values apply equally to all regions.
Parameter
"Mode"
"Reactive Cur-
rent Limit for
Overexcited Op-
eration."
"Reactive Cur-
rent Limit for
Underexcited
Operation."

The R1 threshold must be higher than the R2 threshold, and so on.
The use of identical thresholds for multiple regions is prohibited.
Using the threshold value 0 % is allowed.

Standard Description
value
VFRT function is active ac-
cording to the set para-
meter values.
Off If no special behaviour is
required during grid dis-
turbances, the inverter will
behave according to the
default values in this table
with this setting. Any para-
meter settings made are
ignored.
