Figure 112: Mechanical Master and Slave Follower
As the master axis (the cam lobe) rotates, the follower axis produces a non-linear motion profile. This same profile can then be produced with
a single motor driving a linear axis programmed with an electronic cam.
The cam motion object uses a master/follower principal in a synchronized mode and also has a follower with Realtime mode that allows the
follower to travel through its cam table without a physical master axis moving.
Control Techniques provides a Cam as a collection of cam table(s) that can be used individually of chained together to form a full sequence of
motion. Each cam table is a user specific sequence of movements whereby the user can specify the master and follower movement along with
the interpolation type. Coupled with a user program to monitor the flow, the motion can dynamically be altered by changing the cam table
chains selecting a different sequence of tables. You can further adjust the flow by dynamically changing the cam tables themselves or using a
cam table time base index to adjust time or distance.
As an alternative, the cam is initiated in the same manor as jogs, home and indexes.

Cam Number
Use the arrows of the spin box to increment or decrement the Cam Number and view the setup information for that Cam number. A maximum
of 32 different cam tables can be created.
