Functions and modules
Drive system Ratio-Drive®

As varied as your tasks, requirements, or ideas may be, as versatile is our drive system. Based on your work environment, our experts help you to choose the modules you're still missing, regardless of which or how many components you already have. Thanks to our modular system, we can offer individual components as well as complete systems that allow subsequent expansion or retrofitting.

Possible applications for Ratio-Drive® Automatic control engineering: Examples

With Ratio-Drive® you can realize the most complex control structures – with hydraulic as well as with electromechanical drives.

Intelligent control technology allows you to increase the performance of your drive, to control forces with greatest accuracy, and reproduce complex process structures. The technology uses software controllers that can easily be parameterized for the application in question via a web interface, and that can also feature very complex control structures.


  • Reproducing independently programmed, measured or synthetic operational profiles
  • Synchronizing the movement of several drives
  • Positioning in the micrometer range
  • Oscillations with prescribed amplitudes, frequencies or accelerations
  • Coupling movement and force of the drive
With Ratio-Drive<sup>®</sup> you can realize the most complex control structures – with hydraulic as well as with electromechanical drives.
