Concepts of the cam disc 

4.1

 

Fundamentals 

The term “electronic cam disc” designates applications in which an input angle or an input 
position is depicted through a function on an angle setpoint value or a setpoint position. A 
cam disc is thus a fixed allocation of the positions of a master and a slave.  

 

Master and slave are designated as “master encoder” and “subsequent drive”. The master 
encoder does not necessarily have to be a physical master (see section 4.3), it can also be 
a virtual master (see section 4.4). A master-slave relationship is normally depicted in a 2-D 
assignment graph. The horizontal X-axis includes the position of the master, and the 
vertical Y-axis the position of the slave. And so a statement can be made at any time about 
the relationship between the two drives.

Y: Path slave
