For example: 400V at 50 HzIf the maximum output frequency (P6.4) is set to higher values,the output voltage remains constant as of the cut-off frequencydefined hereAs of this cut-off frequency, the voltage/frequency ratio is nolonger constant. The magnetization of the connected motor isreduced with increasing frequency (field weakening range)Example: Linear V/Hz Characteristic Curve with Cut-OffFrequency and Field Weakening RangeP11.3 603 X — Output voltage 100.0010–200% Input voltageIn the standard application, the value set here is equal to 100%of the input voltage supply and corresponding with the nominalmotor voltage set under P7.5 (see the motor ratings plate)(%)VHzP11.6P11.3P6.3 P11.2(%)VHzP11.6P11.3P6.3 P11.2(%)VHzP11.6P11.5P11.3P11.2P11.4Characteristic Curve: V/Hz (P11.1) LinearP11.1 = 0SquaredP11.1 = 1ConfigurableP11.1 = 2(%)VHzP11.6P11.3P6.3 P11.2 P6.4
