Freq Dep. Power Red - Fronius Galvo Serviceanleitung

Freq dep. Power
Frequency Dependent Power Reduction
Red
(from grid frequency dependent power reduction)
When the GFDPR function is enabled and the specified grid frequency limit value is ex-
ceeded, the effective power is reduced according to a defined gradient.

Frequency Test Time
for setting the waiting time after which the inverter will increase the power again (once the
power has reduced such that the grid frequency is within the permitted frequency range
between Disable Limit Max. and Disable Limit Min.).
