Rising rationalization pressure and an increasing degree of automation in process
engineering demand modern and flexible drive concepts.
The introduction of digital and communicating control devices was an important
step towards the decentralization of control and regulation tasks. An increasing
number of mechanical construction components can be replaced by programmable
servo drives.
In particular mechanical cam switching mechanisms and discontinuous shafts
maintained until today their fields of application in many areas of machine
construction.
Mechanical cam switching mechanisms offer, besides complex motion profiles, a
high positioning accuracy and rigid coupling between master and slave drive.
Their drawbacks are, however, the long changeover times and the limitation to a
defined profile.
In this respect the Compax3 T40 electronic cam offers considerable time
advantages, above all when changing between small batch sizes or with a wide
range of products.
The decentralization of the drive performance can reduce size, costs and
maintenance effort considerably.
Compax3 allows to implement in an axis module all control and drive functions for
a flexible and cost-effective solution of complex motion sequences and
synchronization tasks with the aid of powerful IEC61131-3 modules.
The switching command between different motion profiles takes only seconds – no
fitter or wrench is required.
Large, mechanically coupled drive systems can be divided into small, independent
drives. The dynamic and stationary behavior of every drive can be individually set
and optimized.
