NOTE
When you check the robot position after setting the mark position coordinates, the robot position is not always at
the coordinates specified as the mark position. This is because the mark position is synchronized to prevent
positional shift and make an exact match when the motor's electrical angle is "0".
When the motor's electrical angle is "0", the machine reference is just 50%. This means that as the machine
reference deviates from 50%, the robot position moves away from the coordinates specified as the mark position.
