8.14.2 Synchronisation of the tools with a material

In the case of this relative coupling, the tools are not synchronised with each other but with the

material path (e.g. by means of a touch probe sensor). Therefore in such applications, a master

speed is needed.

[8-10] Principle: mark-controlled synchronisation of the tool to the material

• The master speed is either taken from the material path via an encoder or is stipulated in

advance by the drive that determines the speed (virtual master).

• The tools rotate and are therefore modulo with a fixed modulo cycle.

• The material is modulo with a variable cycle (is measured if necessary, e.g. in the case of foil).

• The curves are created for a nominal cycle/register.

• Adaptation to the measured cycle is carried out individually for each tool in the drive by

means of its own sensors during the runtime.

 Mark track on the material

 Mark sensor for detecting the register on the material (touch probe evaluation within the controller)

 Master value encoder (TTL incremental encoder; supplies speed by means of digital frequency input)

 Controller with electronic cam technology

 Orientation of the tool to the material (here: to the cutting mark)
