3.9.3 Electronic gearbox as cascade

The technology application "Electronic gearbox" is often operated as cascade since

changes of speed/gearbox ratio of an upstream drive also have an effect on the

subsequent drive.

r Typical applications are, for instance, stretching machines, wire drawing machines and

roller mills.

r There is no position reference between tool and material. However, it may be required

to position the tools for maintenance work.

r The master speed is transmitted via the digital frequency or ETHERNET Powerlink.
