opis działania:
Uwagi:
- This action completes with velocity zero if no further actions are pending
- If there is only one mathematical solution to reach the ‘CommandedPosition’ (like in linear systems), the value of the input ‘Direction’ is ignored
- For modulo axis - valid absolute position values are in the range of [0, 360[, (360 is excluded), or corresponding range. The application however may shift the ‘CommandedPosition’ of MC_MoveAbsolute into the corresponding modulo range.
- The Enum type ‘mcShortestWay’ is focused to a trajectory which will go through the shortest route. The decision which direction to go is based on the current position where the command is issued.
