Volt. Dep. Power Red - Fronius SnapINverter Serviceanleitung

Disable Limit Min. / Disable Limit Max.
for setting the upper / lower frequency range limit value
Alt. Ret. Grad Thr.
for setting the threshold above which the "Return Gradient 1" or the "Alt. Return Grad. 1"
is applied.
e.g.:
If the difference between the nominal output and the current reduced power is less than
or equal to the threshold, "Return Gradient 1" is applied.
If the difference between the nominal output and the current reduced power is greater
than the threshold, "alt. Return Grad. 1" is applied.
0.01 - 100 %
100 % means that "Return Gradient 1" is always applied.
Return Gradient 1
for setting the rate of change at which the inverter increases the effective power from the
current reduced value to the original value.
0.01 - 100 %/s
Reference variable
alt. Return Grad. 1
for setting the rate of change at which the inverter increases the effective power from the
current reduced value to the original value;
is activated if the difference between the nominal output and the current reduced power
is greater than the "Alt. Ret. Grad Thr." threshold.
0.01 - 100 %/s
Reference variable
Use Return Grad. 2
for activating/deactivating the rate of change at which the inverter increases the effective
power from the original value to the device nominal output.

Return Gradient 2
for setting the rate of change at which the inverter increases the effective power from the
original value to the device nominal output.

Voltage Dependent Power Reduction
Red
(from grid voltage dependent power reduction)
When the GVDPR function is activated and the specified grid voltage limit value is ex-
ceeded, the maximum effective power is reduced.
The power is reduced by a specified gradient according to the phase with the highest volt-
age.

Device nominal output
Difference between the output at the start of power reduction
and the current output
OFF / ON
the effective power is increased from the original value to the
device nominal output in line with "Return Gradient 1"
the effective power is increased from the original value to the
device nominal output in line with "Return Gradient 2"
