2.6 Special
Adjustments
Voltage stabilization
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).
