12.3 Controller StatusThe intervention of a controller can be indicated via the control unit or LEDs. Theselected control method and the matching monitoring functions prevent a switch-offof the frequency inverter. The intervention of the function changes the operating behaviorof the application and can be displayed by the status messages with parameterController Status 275. The limit values and events which result in the intervention bythe corresponding controller are described in the corresponding chapters.The behavior during the intervention of a controller is configured with the parameterController Status Message 409.Operation mode0 - No Message1 – Warning Status11 –Warning Status andLED12.4 IDC Compensation LimitFunctionThe intervention of a controller is not reported.The controllers influencing the operating behavior aredisplayed in the Controller status 275 parameter.The limitation by a controller is displayed as a warningby the control unit.The limitation by a controller is displayed as a warningby the control unit and the LEDs.At the output of the frequency inverter a DC component can occur in the output currentdue to unbalances. This DC voltage component can be compensated by the frequencyinverter. The maximum output voltage of the compensation is set with parameterIDC Compensation Limit 415. If a higher voltage than the set limit is neededfor the compensation of a DC voltage component, error “F1301 IDC COMPENSATION“is triggered.If this fault occurs, it should be checked whether the load is defective. Possibly thevoltage limit may have to be increased.If the parameter IDC Compensation Limit 415 is reduced to zero, the DC compensationis deactivated.ParameterSettingsNo. Description Min. Max.
