5.5.1

Data flow

The position markers are entered in the »Cam Designer«. The transmission of the cam data to the

controller(s) – together with the corresponding parameter set – is effected via the »Engineer« by

executing the command Transfer parameter set to the device. Afterwards the parameter set and

the cam data have to be saved in the memory module with mains failure protection (e. g. with the

device command C00002 = "11: Save starting parameters").

Tip!
The position markers can also be entered directly via the parameters of the basic drive func-

tion "Cam data management" (LS_CamInterface SB) if cam data have already been down-

loaded to the controller.

Selection of the cam data to be used within the application
Within the application the selection of the position data to be used is then carried out via the pro-

duct number and the track number which have been defined for the axis in the »Cam Manager«:

• The selection of the product number  and therefore the selection of the product to be manuf-

actured for the application is effected globally via the input CAM_dnProductNumber of

the LS_CamInterface SB and has to be carried out synchronously for all cam drives in the inter-

connection.

• The selection of the track number  of the profile data track, however, is effected individually

via the input dnTrackNumber of the corresponding entity of the L_CamPosMarker FB.
