The SM_PLCopen.lib library
POUs for the motion control of individual axes
6.2.23 MC_SetPosition
This program organisation unit shifts the zero point of the axis so that ...
 In absolute mode (mode = FALSE; default), the value defined via the Position input will
become the current set position.
 In relative mode (mode = TRUE), the current set position will be shifted by the Position
value.
Basically, the program organisation unit can be called at any time. However, please note
that in the case of a path-controlled motion, if the set positions are fed to the program
organisation unit directly, via SMC_ControlAxisByPos, for example, a set position jump
may result.
