Hauser Division with 215 employees and a 1997 turnover of 25M¤ develops, manufactures and sells servo drive controllers and automation components. Products are sold to automation companies or end users that have own resources for planning and building automation systems. As part of the FUSE project, a mixed signal ASIC has been developed that implements all peripheral tasks of a drive controller and – together with a digital signal processor (DSP) – forms the basis of the controller’s microelectronics hardware. The controller is used for control of inverters that supply power to drives, which then move parts of machines or goods. This way speed, torque and other parameters of the drive can be controlled.

The ASIC is used to improve the COMPAX family of digital drive controllers for synchronous and asynchronous motors. The old COMPAX was based on one DSP, several digital ASICs and a number of separate analogue components. The product series has many uses, but is employed mainly in applications with fieldbus communications, the packaging machine industry becoming increasingly its main user.

The use of a mixed signal ASIC enables a reduction in material and production costs on one hand and a reduction in size of the microelectronics components on the other. In addition, reliability is increased through a reduction in the number of system components. Functional expansions in ASIC permit a flexible use of the controller in a variety of applications, while a flexible interface to the CPU and the ASIC’s clock frequency permit an improvement of the closed loop algorithms with powerful high-speed DSPs. This is achievable thanks to higher sample rates and more complex control algorithms.

The duration of the project was 26 months, 10 months more than planned; it commenced in August 96. The project costs were estimated at 250.000 ¤, and the payback period at 1 to 1.5 years. The figures result in a return on investment of 250%. In the course of the project, the FU was able to gain experience in project management, design flow and test generation. This experience will help to improve further products. The FU worked in co-operation with a design house and a supplier of semiconductors as subcontractors.

Production costs of a digital servo drive can be considerably reduced with use of the new ASIC. Whilst production costs of a single axis unit is reduced by approx. 15%, the effect is even more distinct for a two-axes unit where the reduction amounts to approx. 35%. For a 3-axes control the costs for required micro electronics may be reduced by up to 50%.

Detailed information

You can also benefit from microelectronics

Mixed-Signal ASIC technology provided HAUSER with the means of improving its products and enhancing its market position. You can also achieve significant benefits by acquiring the right microelectronics technology and utilising it in your product or manufacturing process. You can get help from FUSE to realise this.

FUSE is a technology transfer programme, funded by the European Commission to stimulate the wider use of microelectronics technologies by European enterprises to increase their competitiveness and enhance their economic growth. The demonstrator described here is one of many examples in the public FUSE portfolio covering the whole spectrum of microelectronics technologies and spanning a wide range of applications and industry sectors.

FUSE provides you with:

  • Best practice in acquiring specific microelectronics technologies and conducting full development projects through the FUSE portfolio of real life demonstrator documents.
  • Local training and expert support to plan your innovation realistically and help you conduct your project successfully.
