5. Relations between master/slave axis modes and start modes.

 Master axis is absolute and slave axis is absolute

¾ Relation explanation when master and slave axis are in absolute mode.

In the system where master and slave axis are in absolute mode, master axis starts moving

with the physical position of current point as the starting position when CamIn is executed.

Slave axis will make the cam motion following master axis with the current physical position

corresponding to master position as the starting position, which conforms to the

corresponding cam relation.

¾ 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 cam curve and C2 is the electronic cam curve for actual motion.

n Start-up mode 0: start up by jumping to the positive target position immediately. In one

synchronous cycle, slave axis jumps from current position to the target position. The

meshing time is the shortest and the vibration is the strongest in process of meshing.

<1> When master axis is in absolute mode, master position in cam curve = ( master

position 144 + master offset 0) / master scaling 1 =144.
