The NORDAC PRO is the inverter for all drive applications. It offers a wide power range, and its functionality can be extended with plug-in option modules. For this inverter, variable cooling concepts are used to remove heat, which enable removal of heat outside of the control cabinet and can be simply adapted to the requirements of the application with various option modules.

  • Operation of synchronous and asynchronous motors
  • Functions can be extended with plug-in control or communication modules

  • POSICON - integrated positioning mode and synchronisation
  • An external brake rectifier can be controlled with NORDAC PRO via a digital output or multi-function relay
  • High precision regulation with current vector control
  • PLC functionality for functions close to the drive unit, for example status monitoring of the drive unit for pre-processing of process data
  • Energy-saving function in the partial load range
  • Control and parameterisation tools and simple parameter structure
  • Integrated line filter for compliance with EMC regulations
  • Control and closed loop regulation

Treif food processing

Intelligent cutting

Treif Maschinenbau GmbH is one of the world's leading manufacturers of equipment for cutting food. For a high degree of flexibility, the machine manufacturer relies on drive technology from NORD.

Stage Technology in the Duisburg Theatre

Smooth positioning

The regular performances at the Duisburg Theater demanded a renewal of the drive systems for the operation of the backdrop a few years ago. NORD offers individual solutions here.


Metered moving

For their maintenance and cleaning systems for challenging architecture, Góndolas in Design chose NORD drives for the accurate and safe positioning of the gondola systems.


Custom drive solutions for construction hoists

NORD drive systems move STROS construction hoists up to a height of 300 meters with a precise, strong performance and are also characterized by smooth starting and braking.
