5.6.1

Data flow

The motion profiles (curves) are entered or imported in the »Cam Designer« by means of graphical

objects (point, line, polynomial). 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 sa-

ved in the memory module with mains failure protection (e. g. with the device command

C00002 = "11: Save starting parameters").

Tip!
The motion profiles (curves) can also be entered directly via the parameters of the basic dri-

ve function "Cam data management" (LS_CamInterface SB) if cam data have already been

downloaded to the controller.

Selection of the cam data to be used within the application
Within the application the selection of the profile data to be used is then carried out via the product

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 motion profile, however, is effected individually via

the input dnTrackNumber of the corresponding entity of the L_CamProfiler FB.
