4. Motion Control Instructions Motion curve: Suppose the current physical positions of axis 2 and axis 1 are 0 and 90 respectively, i.e. point A below and the two axes have been enabled. The motion curve is shown below after the cam function is performed. As M1 turns Off ->On, “CamTableSelect” is executed. M17 is on after the execution of “CamTableSelect“ is finished. As M2 turns Off ->On, “CamIn” is executed. According to cam meshing method, we can see that slave axis will jump from point A to point B immediately and meanwhile, M19 is on.
As M3 turns Off ->On, master axis executes the velocity instruction and slave axis will start the motion following master axis according to cam curve. As M4 turns Off ->On, “CamOut” is executed and the master-slave relation is disconnected; Slave axis will move at the speed when master-slave relation is disconnected. As M5 turns Off ->On and M24 is on, slave axis stops moving and master axis moves at a constant speed. 4-80 DVP-MC operating manual
