2.3.6. CAM Function

The cam is the component with the curve profile or grooves. It transmits the motion to the follower near its

edge and the rack will turn periodically following the follower. The cam mechanism consists of a cam, follower

and rack. The following figure shows the cam profile made up of point A, B, C, and D. AB' is a follower which

is connected to the rack. δ4 is an inner angle of repose; δ2 is an external angle of repose. The radius of the

base circle is r0 and S is the cam curve.

The electronic cam is an analog cam of the mechanical cam by applying computer technology. Compared

with the mechanical cam, the electronic cam has many advantages of being easy to design and modify; cost

saving; higher efficiency and preciseness. Because the electronic cam is an analog cam, these defects of a

mechanical cam like being easy to be damaged and not fit for high-speed rotation and transmission can be

avoided for the electronic cam.

DVP10MC11T controller supports the function of the electronic cam. User can edit the cam curve in the cam

editor provided by CANopen Builder as follows.
