4. Motion Control Instructions Start-up mode 2: start up toward positive direction. Slave axis moves from point A to point B to mesh with master axis at the max. speed, max acceleration and max deceleration. When master axis is in absolute mode, master position in cam curve = (master position 144 + master offset 0) / master scaling 1 =144. From cam curve, slave position is 164 when master position is 144. Calculation method: f (144) =164. When slave axis is in absolute mode, slave position= 164* slave scaling 1 + slave offset 0 =164 Because startup mode 2 is to rotate toward the positive direction, slave axis should move from current position to the position 164 in the next cycle, i.e.
actual position 524 and thus the coordinate of the meshing point B is (144,524). When master axis moves, following master axis, slave axis starts to move from point B according to C2 curve. DVP-MC operating manual 4-63
