When using the independent mode and the axes are synchronized, all

but the last axis to finish the move in process will stop motion when

finished and wait for the last axis to complete its move. All axes will

then begin the next move simultaneously as soon as the last axis has

finished its move. The process then repeats for each move in the

positioning profile (Figure 3.5).
