01/02 AWB8230-1413GB Programmable relay outputsK11 to K34Motor thermal overload (THM)The <strong>DF6</strong> frequency inverters simulate a bimetal element to protectthe motor. With its default setting, it exhibits the illustratedcharacteristic.J[s]If the motor current is greater than the set tripping current(dependent on the frequency inverter), the <strong>DF6</strong> frequency inverterissues fault message E05 <strong>and</strong> switches the output voltage V2 2off. With a relay output configured as THM, the frequency inverteroutputs a signal before issuing the fault message. The THM outputis activated when the motor exceeds the current set underPNU C061 PNU C061 is the tripping current in %. The magnitudeof the tripping current depends on the tripping characteristicdefined under PNU b013 (a section “Electronic motorprotection”, page 135).60THM0.5K23 K240 25.5 A116 %33 A150 %44 A200 %15...30 V 0. 250 V DFigure 102: Tripping characteristic using a <strong>DF6</strong>-<strong>340</strong>-11K as anexample, with the tripping current set to 22 At: Tripping timeI: Motor currentFor a detailed description of how to set parameters PNU b012 tob020 for tripping, see section “Electronic motor protection”,page 135.Figure 103: Relay output K23-K24 configured as THM (motor thermaloverload)X Under PNU C061, enter the percentage value of the trippingcharacteristic at which the THM output is activated.X Program one of the relay outputs K23-K24 or K33-K34 as THMby entering the value 13 in the corresponding PNU (C021 orC022) or in PNU C026 for signalling relay contacts K11-K12.PNU Name Adjustable in RUN mode Value Function WENormalExtendedC061Thermaloverloadwarning– j 0 to 100 % The entered value relates to the tripping characteristic setunder PNU b012 to b020.When the value set here is exceeded, the digital outputconfigured as THM is activated.80101
