Using the Electronic CAM Feature
Section 1: Introduction
This chapter introduces the reader to the DSM314 release 2.0 electronic CAM function. An
electronic CAM is analogous to a mechanical CAM. In most cases, an electronic CAM not only
can replace the traditional mechanical CAM but performs many functions not achievable with its
mechanical counterpart. For example, an electronic CAM never mechanically wears out.
Electronic CAM Overview
Electronic CAMs are used in the machine industry to perform complex motions that require tight
coordination between axes. There are many examples of applications that fit these requirements.
Some examples are a simple rotary knife application shown in Figure 16-1 and Figure 16-2. In this
application, the conveyor belt position serves as the master position, while the cutting knife is the
slave. Since the knife position is linked to the master position, the knife always tracks the master
position even when the line is accelerating or decelerating.
