Application example
4.1 Application example
In the application example used for short setup, the technology application "Electronic
gearbox" is operated as cascade since changes of speed/gearbox ratio of an upstream drive
also have an effect on the subsequent drive.
 Typical applications are, for instance, stretching machines, wire drawing machines and
roller mills.
 There is no position reference between tool and material. However, it may be required
to position the tools for maintenance work.
 The master speed is transmitted via the digital frequency (digital frequency extension
module required).
