Figure 2.1 E-Cam and the Machine Cam
In E-Cam system, the cam makes the motion based on the E-Cam curve. The position of master
and slave is a one-to-one function relation, which is the E-Cam curve function. The function of
master axis is to send pulses to the slave axis. The slave axis will move according to the
received pulses and the corresponding E-Cam curve.
