......Setting Parameters01/02 AWB8230-1413GBLinear U/f characteristicFor a constant torque, enter the value 00 under PNU A044(default). The <strong>DF6</strong> frequency inverter then increases the outputvoltage U 2 on a linear ramp up to the base frequency inPNU A003.U 2[%]Adjustable U/f characteristicFor a freely programmable torque, enter the value 02 underPNU A044. Under PNU b100 to b113, you can assign sevendifferent frequency-voltage pairs to the <strong>DF6</strong>. However, frequenciesf 1 to f 7 must have ascending values: f 1 F f 2 F f 3 F ...F f 7 .
