RUN Value/Range Description
Factory Setting
(P1.3)
P11.2 602 X — Cut-off frequency 60.00
30–320 Hz The output voltage reaches its maximum rated value P11.3 with
the cut-off frequency. For example: 400V at 50 Hz
If the maximum output frequency (P6.4) is set to higher values,
the output voltage remains constant as of the cut-off frequency
defined here
As of this cut-off frequency, the voltage/frequency ratio is no
longer constant. The magnetization of the connected motor is
reduced with increasing frequency (field weakening range)

P11.3 603 X — Output voltage 100.00
10–200% Input voltage
In the standard application, the value set here is equal to 100%
of the input voltage supply and corresponding with the nominal
motor voltage set under P7.5 (see the motor ratings plate)
