7.5.1.3 Additional rated point (uF.02 / uF.03)
To adapt the V/f-characteristic to special conditions an additional rated point can be specied with uF.02 and
uF.03. uF.02 denes the frequency and uF.03 the voltage. At uF.02 = 0 Hz the adjustment is ignored. The
parabolic characteristic is activated with uF.02 = „-1: parabolic characteristic". Then parameter uF.03 has no
function.

7.5.1.4 Voltage stabilisation (uF.09)
The DC link voltage and thereby the directly dependent output voltage can be changed by uctuations of the
mains voltage or the load. In the case of enabled voltage stabilization the uctuations of the output voltage are
compensated. I.e., 100% output voltage correspond to the value set in uF.09 , but maximally 110% · (UZK / √
2), depending on the setting of uf.10. This function further allows operation of motors with a low nominal voltage
at the inverter.
