2.3.4. CAM Function
CAM is a component with curve profile or grooves. It transmits the motion to the follower near its edge and
the rack will turn around periodically following the follower. CAM mechanism consists of CAM, follower and
rack. The following figure is the profile chart of CAM made up of point A, B, C, and D. AB' is a follower which
is connected to rack. δ4 is an inner angle of repose; δ2 is an external angle of repose. The radius of base
circle is r0 and S is the diagram of CAM.
Figure 2.3.3
Electronic CAM is analog CAM of mechanical CAM by means of applying computer technology. Compared
with mechanical CAM, Electronic CAM has many advantages of being easy to design and modify; cost
saving; higher efficiency and preciseness. Because electronic CAM is analog CAM, these defects of
mechanical CAM like being easy to be damaged and not fit for high-speed rotation and transmission can be
avoided for electronic CAM.
DVP10MC11T controller supports the function of electronic CAM. User can edit the CAM curve in the CAM
editor provided by CANopen Builder as follows.
