The following parameters serve for the optimization of the drive and the adaption to certain
applications. These adjustments can be ignored at the initial startup.
With this parameter a regulated output voltage in relation to the rated frequency can be
adjusted. For that reason voltage variations at the input as well as in the intermediate
circuit only have a small influence on the output voltage (U/f-characteristic). The
function allows, among other things, an adaption of the output voltage to special motors.

Note:
In the example below the output voltage is stabilized to 230 V (0% boost).
