7.7.8.1 Change Current Position

MC_SetPosition
This function block is to change the current position by shifting the coordinate system of an axis.
The changing of the coordinate system is made by modifying both the current position of the instruction
(command position) and the actual position from the feedback signals with the same value.
The following error between command position and actual position remains the same value.
The function block is used to change the coordinate system and does not lead to servo drive and motor
movement.
