20.15 L_SSC_SetAxisData - machine parameters
With this FB the machine parameters of a higher-level drive can be mapped. The FB
conditions the machine parameters, which you specify in the physical units of the machine
via parameters, for the internal representation.
 At the output scAxisData the FB provides a pointer to the data structure with the
machine parameters conditioned.
 In order to pass the machine parameters to another FB which requires these data for
internal calculations, the output scAxisData is to be connected to the input with the
same name of the corresponding FB.
