When falling below the integrator counts backwards.Error E.OL is triggered if the integrator achieves the inverter appropriate overload characteristic.3.2 Overload protection in the lower speed range(only for F5-M and F5-S)Load [%]E.OL2 E.OLOC-tripping currentShort time current limitStart of overload integrator at105%Stand still current(see technical data)f [Hz]Min. frequency at continuous full load(see technical data)A PT1-element (τ = 280 ms) starts if the permissible current is exceeded. After its sequence of operation errorE.OL2 is triggered.3.3 Calculation of the motor voltageThe motor voltage for dimensioning of the drive is depending on the used components. The mains voltage redu-ces according to the following table:Mains choke Uk 4 % Example:Inverter open loop 4 % Closed loop inverter with mains- and motor choke at non-rigid supply system:400 V mains voltage - 15 % = 340 V motor voltageInverter closed loop 8 %Motor choke Uk 1 %Non-rigid supply system 2 %
