Feed control7.2 Traversing positioning axes (POS, POSA, POSP, FA, WAITP, WAITMC)Fundamentals118 Programming Manual, 09/2011, 6FC5398-1BP40-2BA07.2 Traversing positioning axes (POS, POSA, POSP, FA, WAITP,WAITMC)FunctionPositioning axes are traversed independently of the path axes at a separate, axis-specificfeedrate. There are no interpolation commands. The POS/POSA/POSP commands are used totraverse the positioning axes and coordinate the motion sequences at the same time.The following are typical examples of positioning axes:• Pallet feed equipment• Gauging stationsWAITP can be used to identify a position in the NC program where the program is to wait untilan axis programmed with POSA in a previous NC block reaches its end position.WAITMC loads the next NC block immediately when the specified wait marker is received.SyntaxPOS[]=POSA[]=POSP[]=( position>, length>,)FA[]=WAITP() ; Programming in a separate NC block.WAITMC( marker>)SignificancePOS/POSA: Move positioning axis to specified positionPOS and POSA have the same functionality but differ in their block changebehavior:• POS delays the enabling of the NC block until the position has beenreached.• POSA enables the NC block even if the position has not been reached.: Name of the axis to be traversed (channel or geometryaxis identifier): Axis position to be approachedType: REAL
