Synchronizing controller
As can be seen from the diagram below, at Start, as well as with every change in
speed of the master drive, the cycle times are added; they are then compensated
for again based on the control characteristics of the controller in question.

In this case, the same application is realised by means incorporating a virtual
master. Although the way that the reference value is introduced at the first
belt is analogous, the value is used to set the virtual master signals.
