Graphic illustrating the limits
In backup power mode, the inverter itself determines the frequency and the fre-
quency limits are therefore not active.
"Inner Limits"
Parameter
"Underfrequency f<"
"Underfrequency Time

"Overfrequency f>"
"Overfrequency Time

"Outer Limits"
Parameter

"Alternative Limits"
For the inner frequency limit values there is an additional second parameter set,
which is only relevant for Italy. In order to activate this second parameter set, the
alternative frequency limit value must be set to "On" on the user interface of the
inverter and activated/deactivated via an external signal as follows:
-
