60.00
30.00 – 320.00 Hz
The output voltage reaches its maximum rated value P11.3 with
the cut-off frequency. For example: 400 V 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).
Example: linear U/f characteristic curve with cut-off frequency and
field weakening range.
P11.3
603 - Output voltage 100.00
10.00 – 200.00 % of mains voltage
In the standard application, the value set here is equal to 100 %
of the mains voltage supply and corresponding with the nominal
motor voltage set under P7.5 (
h ratings plate motor).
