Baumüller Expands Motion Control Concept

Project planning of coupled and synchronous motion control functionalities without system knowledge

Nuremberg/Hartford. The Baumüller Group, manufacturer of electric drive and automation systems from Nuremberg, expanded its new motion control concept. In addition to the previously established function modules for motion control single axis applications, Baumüller now also offers modules for coupled and synchronous functions, the so-called multi-axis applications. This allows for configuring even complex machine functions, such as cam disk, electric gearbox or out-of-phase movements, without functional knowledge using a purely technological perspective.

As early as the end of the year 2002, the Baumüller Group introduced its motion control concept based on PLCopen standard. The concept perfectly converts the central requirements of the machine manufacturer to simplifying the automation software and reducing the expenses for software initialisation, update and maintaining. The motion control concept allows for project planning motion functionalities from a purely technological perspective using the libraries function module, thereby allowing the machine manufacturer to concentrate on the continuous development of his machine fu nctio nal ities.

Since only single axis modules have been available for software project planning so far, Baumüller has now expanded the programming library of the motion control concept by multi-axis function modules. As a system expansion, the multi-axis functionalities build on the basis of the single axis programming library. Motion control multi-axis enables coupled synchronous path motion of several axes.

In addition to the cam disk basic function, the electronic gear, superimposed positioning, master phasing and virtual leading axis functionalities are now available as new function modules. Axis couplings of master and slave are carried out at the command and synchronously converted by the system.

A new feature is the expansion of integrated tools into the development environment. The axis configurator that was already required for the single axis functions was expanded by a data record manager for the cam disk function. The data record manager takes graphically represented curve profiles to create the corresponding data records and carries out the download of the data records to the PLC in the drive. Using an additional feature, the cam disk editor, user-defined curves can be individually designed and saved. They are subsequently available to the control via the multi-axis commands of the cam disk.

Analogous to the single axis motion control concept, IEC 61131 serves as the programming language. The required system functionalities for motion management, fieldbus communication and drives are integrated in the operating system of the b maXX automation system from Baumüller by means of communication and motion managers. The Baumüller automation interface took the demand for uniform engineering and commissioning tools working interactively with each other into account. The automation interface establishes the connection of the individual tools, such as IEC 61131 programming system, drive/unit and fieldbus configurator and, at the same time, serves as the control of relevant tool functionalities. All information, data and parameters of the individual tools can now be consistently maintained by using a common project database.
