12.1.7 Absolute or relative master angle processing?
Absolute master angle processing
All drives have a common fix reference to each other via the position of the master angle.
Relative master value/master angle processing
Stands for a high-precision transmission of the master value. However, there is no firm
reference to the other drives (e.g. in case of a material path each printing roll is
synchronised one by one to the print image).
12.1.8 Functions with synchronisation via the electrical shaft
The functions of the electrical shaft are built on each other and thus are scalable:
Electronic gearbox
The electronic gearbox respresents the simplest function in the DC-bus operation via the
electrical shaft. The function is suited for e.g. material transport or material processing. A
direct synchronism of tools to a material path can be created without direct position
reference or for stretching plants with adjustable stretching ratio.
TA "Electronic gearbox"
(C 297)
Absolute synchronism
This function is suited for applications with continuously rotating tools (e.g. groove
cylinder), which are fed with material in a fixed machine cycle and for which several tools
have to be synchronised to each other.
Relative synchronism (with mark synchronisation)
This function is suited for processing continuous material in the form of a material web.
Here the tools (e.g. pressure cylinders) are aligned via marks to e.g. print images which are
located on the web. There must be no risk of collision. We distinguish between "Relative
synchronism with register formation and mark synchronisation" and "Relative
synchronism with register control".

Absolute table synchronism (cam)
Like "Absolute synchronism", although the tools can also perform a non-linear movement.
