Enable Input. Therefore, the general rules for the Enableinput do not apply here. This function block is implicitlyenabled. The Enable input of this function block controlsthe DC-link voltage on the output lines of the SAB. Alloutputs are always updated (so Valid can be TRUE, even ifEnable is FALSE).The input TimeLimit represents the maximal duration offunctionality. If the TimeLimit is exceeded during switchingon the SAB, an Error is signaled at the outputs. However,the functionality according to the Enable input iscontinued. If Enable is TRUE, the function block continuesto attempt to enable the DC-link voltage of the SAB. IfEnable is FALSE, the function block continues to attempt todisable the DC-link voltage of the SAB. If the SAB startsreacting again, the Error output can change to FALSE againwithout a new rising edge of Enable. Set the value to 0 todisable the time limit functionality.The command is transferred immediately, but it can takesome time until the SAB has enabled the DC-link voltageand the output Status becomes TRUE.6.5.8.3 DD_Reset_SABThis function block makes the transition from the stateFault to Standby by resetting all internal SAB-related errors.It does not affect the output of the function blockinstances.The command is transferred and executed immediately.DD_Reset_SABSabExecuteBOOLSAB_REFBOOLDoneBOOLBusyBOOLDD_ERROR_ISD51xErrorInfoError130BE966.10Illustration 6.86 DD_Reset_SABVariablenameDatatypeDefaultvalueDescriptionVAR_IN_OUTSab SAB_REF Reference to the SAB.See chapter 6.5.8.1 SAB_REF.VAR_INPUTExecute BOOL FALSE Resets all internal SAB-relatederrors.VAR_OUTPUTDone BOOL Standby state is reachedBusy BOOL The function block is notfinished and new output valuesare to be expected.Error BOOL An error has occurred withinthe function block.ErrorInfo DD_ERROR_ISD51x Error identification and instanceidentifier.See chapter 6.5.2.3 ErrorIndication.Table 6.72 DD_Reset_SAB6.5.8.4 DD_ReadSabInfo_SABThis function block returns detailed information about theSAB.The output data is available immediately.DD_ReadSabInfo_SABSabEnableBOOLSAB_REFBOOLValidBOOLBusyBOOLDD_ERROR_ISD51xErrorInfoBOOLCommunicationReadyBOOLReadyForPowerOnBOOLPowerOnBOOLSabWarningBOOLSabErrorError130BE967.10Illustration 6.87 DD_ReadSabInfo_SABVariablenameDatatypeDefaultvalueDescriptionVAR_IN_OUTSab SAB_REF Reference to the SAB.See chapter 6.5.8.1 SAB_REF.VAR_INPUTEnable BOOL FALSE Get the SAB informationcontinuously while enabled.VAR_OUTPUTValid BOOL The function block has a validset of outputs.Programming VLT® Integrated Servo Drive ISD® 510 System222 Danfoss A/S © 01/2017 All rights reserved.
