NORDCON

With the NORDCON Windows app and the NORDCON mobile app, NORD provides the right tool for commissioning and drive optimisation. Both enable easy access to electronic drive systems, simple parameter management and comprehensive diagnosis.

Device description files

The implementation of NORDAC options in automation environments is particularly easy with the corresponding device description files (EDS, ESI, XML and GSD). All relevant files are ready for direct download – matched to the drive systems from NORD DRIVESYSTEMS. Efficient configuration, reduced installation times and increased productivity with one click.

ePLAN macros

ePLAN macros from NORD DRIVESYSTEMS enable simplified planning and speed up the entire engineering process. The verified macros are available for direct download and allow precise mapping of the drive systems, efficient preparation of circuit diagrams and reliable error prevention.

Condition Monitoring

We support the continuous condition monitoring of our drive solutions with the aid of a wide range of sensors, software architectures and interfaces. This not only allows for permanent data collection and processing but also for predictive maintenance and thus increased efficiency and availability of your drive technology.

Energy efficiency and TCO consulting

With both our innovative products and comprehensive service offers, we support you in finding the most suitable and energy-efficient solution for your drive technology. All our drive components, whether gear unit, motor or frequency inverter, are optimised for resource-saving use.

Commissioning

With tailor-made service packages, we support you with the commissioning of your NORD drives. We help you with the commissioning of individual drive components or complete drive systems, as well as with their connection to your automation environment. Our service is available by phone, remotely or personally on site.

Product variants and applications

NORD provides you with tailor-made drive solutions from a single source. Each component in our modular product system can be extended with a motor, a gear unit, drive electronics and accessories. With personalised advice, we help you implement the best drive solution for your application. Find out more about the possibilities this product offers:
