4. Motion Control Instructions
DVP-MC operating manual 4-51
p 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.
<1> When master axis is in absolute mode, master position in cam curve = (master
position 144 + master offset 0) / master scaling 1 =144.
<2> From cam curve, slave position is 164 when master position is 144. Calculation
method: f (144) =164.
<3> When slave axis is in absolute mode, slave position= 164* slave scaling 1 + slave
offset 0 =164
<4> 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.
