13.23 L_LCB_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.
• The FB outputs a pointer to the data structure with the prepared machine parameters at the
output scAxisData.
• In order to pass the machine parameters to an 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.
