Example 2: 4-axis application with HEDA
Task:
 four-axis processing machine
 Setting the steps via virtual master
 Forwards and backwards movement with the master (closed curve)
 Linearized feed movement with Slave 1 = rotating blade (open curve)
 Position synchronous operation of slave 2 with respect to slave 1 with slip
correction (use of C3_Shift_Position)
 Fixed position assignment of a turning axis slave 3 to slave 2 with consideration
of the correction movement of slave 2
