4.3.6 Special
Adjustments
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.
Adjustment range: 1...650 V (off)
Resolution: 1 V
Factory setting: 650 V (off)
Note: Enter-Parameter
In the example below the output voltage is stabilized to 230 V (0% boost).
