Several Operator Panels on Several NCUs, Distributed Systems (B3)2.7 Axis containerExtended FunctionsFunction Manual, 01/2008, 6FC5397-1BP10-3BA0 155The variant below is used with a view to facilitating commissioning:Programming CommentAXCTSWED(CT1) ; The function name represents:AXis ConTainer SWitch Enable DirectThe axis container rotates according to the settings in setting data:SD41700 $SN_AXCT_SWWIDTH[container number]This call may only be used if the other channels, which have axes in the container are in theRESET state.NoteThe axis container names allotted through the following machine data can be used for theAXCTSWE and AXCTSWED commands:MD12750 $MN_AXCT_NAME_TABImplicit waitThere is an implicit wait for the completion of a requested axis container rotation if one of thefollowing events has occurred:● Part program language commands which will cause a container axis assigned to this axiscontainer in this channel to move● GET(channel axis name) on a corresponding container axis● the next AXCTSWE(CTi) for this axis containerNoteEven an IC(0) will result in a wait including synchronization where necessary (block-by-block change in addressing according to increment even though absolute dimension isset globally).Synchronization with axis positionIf the new container axis assigned to the channel after a container rotation does not have thesame absolute machine position as the previous axis, then the container is synchronizedwith the new position (internal REORG).NoteSD41700 AXCT_SWWIDTH[Container No.] is updated only for new configurations.If, after incremental rotation of the RTM/MS, the position of a circuit before the initial positionis reached, the container can be rotated normally in the forward direction to reach the initialposition of the container again. The drum or rotary table must however be turned back to theoriginal position, so that measuring and supply cables are not twisted.
