<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 relative mode, slave position= 164* slave scaling 1 =164

<4> When slave axis is in relative mode as well as any start-up mode, its actual position

at point B is 227 and the corresponding position in the cam curve is 164. And so the

coordinate of the meshing point B is (144,227). When master axis moves, following

master axis, slave axis starts to move from point B according to C2 curve

 Master axis is relative and slave axis is absolute

 Relation explanation when master and slave axis are in relative and absolute mode

respectively.

In the system where master and slave axis are in relative and absolute mode respectively,

master axis starts moving with the physical position of current point as the starting point of the

cam system when “MC_CamIn” is executed. Slave axis will start the cam motion following

master axis from its position corresponding to the starting point of master axis in the cam

system.

 StartMode parameters explanation:

In the following figure, master and slave axis are both static before and after meshing. Point A

is the position of master and slave axis before meshing; Point B is the meshing point; C1 is

the preplanned electronic cam curve and C2 is the electronic cam curve for actual motion.

 Start-up mode 2: Start up toward the positive direction. Slave axis moves in the positive

direction from point A to point B at the max. velocity, acceleration and deceleration in axis

parameters to mesh with master axis.
