Introduction To Electrical Cam (E-Cam) - Delta DVP-PM Series Applications Manual

9.1 Introduction to Electrical CAM (E-CAM)

Mechnical cam system consists of 3 parts including a cam, a cam follower, and a fixed linkage.
Mechinacal cam is a rotating piece with irregular form, usually an input device with steady rotation rate,
operates cam follower to produce a smooth reciprocating motion through the fixed linkage between the
cam and the follower.
Cam follower is a type of roller or needle bearing designed to be driven by the cam. Usually the cam
follower is an output device for producing discrete signals.
Fixed linkage is the frame for linking and fixing the cam the the follower.
In comparison with mechanical cam system, there are many advantages of using E-CAM
E-CAM provides a more user-friendly interface.
Not necessary to modify machinery system when different production process is required. Users only
need to modify the E-CAM data in CAM chart by software.
Higher acceleration speed can be achieved.
Operation is smoother.
