SMC_TRAFOF_GantryCutter2 (FB)¶

FUNCTION_BLOCK SMC_TRAFOF_GantryCutter2

Forward transformation for two-dimensional gantries with a cutter knife. The rotation axis is controlled in such a way that the knife is aligned along the path tangent.

Note

For more information see Gantry Cutter. For detailed information on transformations see overview to SM_Trafo_POUs.
