Short setup

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).
