The electronic cam enables angle-synchronous relative movements
between a master and slave drive. It acts as a substitute for mechanical
eccentric cams or cranks, as illustrated in the figure below:

Up to 400 coordinate pairs describe the relative movement by means of
table interpolation. These 400 interpolation points can be subdivided
into one to eight curves; x and y-axis coordinates can be entered
separately; the x values do not have to be equidistant. These
parameter settings can naturally also be configured via PROFIBUS-DP,
and the cam can therefore be modified in a matter of seconds.
