MDS Series

Modular Drive System for Multi-axis Servo Drive Solutions

MDS Series

4.0 A – 34.0 A rms (8.0 A – 68.0 A peak)

230 V | 460 V

The Modular Drive System (MDS) is a powerful and cost effective solution for applications with multiple axes. The MDS utilizes a unique backplane architecture that provides a common bus platform for one of three sizes of power modules and up to eight drive modules.

The MDS modules can operate on a 230V or 460Vac input. Plus, there are five different sizes of drive modules to meet the needs of almost any multiple axis application. FM control modules provide MDS drives with “snap-in” functionality for indexing (FM-2), programming (FM-3E) and advanced programming (FM-4E). This modular approach allows users to choose the level of advanced machine control they need based on the application's requirements.

As part of our "buy what you need" philosophy, the MDS motion functionality is easily scalable by adding on FM modules.

  • Options

    FM control modules provide EN drives with “snap-on” functionality for Indexing (FM-2), Programming (FM-3E), and Advanced Programming (FM-4E). This modular approach allows users to choose the level of advanced machine control they need, based on the applications parameters and not the drive “spec”.

    For applications requiring traditional multi-axis control, our MC controller is easily integrated with a single cable connection. These modules are programmed using the our PowerTools Pro software.
