Energy Saving
Function
The energy saving function allows the lowering or raising of the current output voltage.
In accordance with the activation conditions defined in uF.6, the voltage valid according
to the V/Hz-characteristic is changed in percent onto the energy saving level (uF.7).
However, the maximal output voltage cannot be higher than the input voltage even if
the value is > 100 %. The function is used for example in cyclic executed load/no-load
applications. During the no-load phase the speed is maintained, but energy is saved
as a result of the voltage reduction.
