Parker EME Motion control192-121102 N04 June 2008 2375.10.6.2 Recording the position of the selected master source(C3_MasterControl)FB name C3_MasterControlStart and Stop of the master detectionVAR_IN_OUTSlave INT Axis-ID (library constants)VAR_INPUTEnable BOOL Starting the module.Acquisition is started or stopped in accordance with theModeStartMode INT Selection of the Start mode1: Start of the detection with rising edge of the enable2: Fast start after external event (Impulse). Defined by”StartSource” and ”StartMask”, , does start within 0.5ms.3: Start of the acquisition with the next encoder zero pulse,after the start of the modules (Enable = TRUE)StartSource DWORD Specification of an object (see example) for starting thedetection.Only relevant with StartMode 2.The address operator ADR () must be used for the selectionof an object.StartMask WORD Binary mask for and-linking the source in order to select abit from the source object.Only relevant with StartMode 2.StopMode INT Selection of the Stop mode1: Stops the acquisition with falling edge of the Enable2: Stops the detection at the end of the master clockdistance. Defined via the curve or via C3_MasterConfig(see page 243).Periodic BOOL False: run trough onceTrue: cyclic runBackStop BOOL False: Backstop not activeTrue: Back stop activeMaster INT Axis- ID of theMaster signal source (see page 161)AXIS_REF_HEDA: HEDAAXIS_REF_Physical: +/-10V, step/direction/ EncoderAXIS_REF_Virtual: virtual MasterVAR_OUTPUTStatus BOOL Shows that the master position acquisition is runningEndOfProfile BOOL Impulse at the end of the configured master cycleBusy BOOL Waiting for an external eventError BOOL Command was aborted; error when starting the detectionNote: Witht the active enable, the "Periodic" and "Master" inputs are always accepted. With the transition Enable low to high the StartMode is evaluated. With the transition Enable high to low the StopMode is evaluated. Only one module controlling the detection is allowed in the project. Enable and StartSource must have different sources.
