4. Motion Control Instructions When master axis is in relative mode, master position in cam curve = (master position 0 + master offset 0) / master scaling 1 =0. From cam curve, slave position is 0 when master position is 0. Calculation method: f (0) =0. When slave axis is in absolute mode, slave position= 0* slave scaling 1 + slave offset 0 =0 Because startup mode 2 is to rotate toward the positive direction, slave axis need move from current position to the position 0 in the next cycle, i.e. actual position 360 and thus the coordinate of the meshing point B is (144, 360). When master axis moves, following master axis, slave axis starts to move from point B according to C2 curve.
Start-up mode 3: Start up toward the negative direction. Slave axis moves in the negative direction from point A to point B at the max. velocity, acceleration and deceleration in axis parameters to mesh with master axis. DVP-MC operating manual 4-67
