4. Motion Control Instructions 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 0 is to start up by jumping to the positive target position direction immediately, slave axis need 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. Start-up mode 1: start up toward the shortest distance and slave axis judges whether to mesh toward the positive or negative direction according to the distance between current position and target position. Slave axis moves from point A to point B to mesh with master axis at the max. speed, max acceleration and max deceleration in the axis parameters. 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 1 is to start up toward the shortest distance and the position 164 in the current cycle is the most closest to current slave position, slave axis need move from current position to the position 164 in the current cycle, i.e. actual position 164 and thus the coordinate of the meshing point B is (144,164). When master axis moves, following master axis, slave axis starts to move from point B according to C2 curve. 4-62 DVP-MC operating manual
