en.Wedoany.com Reported - Germany NORD DRIVESYSTEMS has introduced a new modular system, offering greater design freedom for system configuration. The system integrates distributed drive electronics with high-efficiency motors into a unified platform, centered around two frequency inverters: Nordac Link and Nordac On—both now feature identical communication and safety functions, allowing flexible use.
Large-scale internal logistics systems for e-commerce platforms, parcel sorting centers, or airports often require space-saving distributed drive solutions. However, planners frequently face a challenge: if wall-mounted and motor-mounted frequency inverters have different safety and communication characteristics, additional wiring is needed. NORD's new modular system provides a solution, enabling users to deploy distributed drive electronics consistently.
The modular system includes NORD asynchronous IE3 motors, synchronous IE5+ motors, and two distributed frequency inverters: Nordac On (power range 0.37–3.7 kW, supports wall and motor mounting) and Nordac Link (power range 0.37–7.5 kW, wall mounting only). Both feature completely identical communication and safety functions, significantly expanded by NORD. The inverters have a built-in Ethernet interface, are compatible with Profinet and EtherCat fieldbuses, and can be seamlessly integrated into safety-critical applications via PROFIsafe or FSoE. An extended safety function package is integrated: STO, SS1-t (compliant with SIL3/PLe), as well as SS1-r, SLS, SMS, SSM (compliant with SIL2/PLd), all without the need for an encoder. Safety inputs/outputs can be directly connected to safety-critical components such as emergency stop buttons or photoelectric sensors.
In dynamic applications, Nordac On and Nordac Link enable encoderless control of high-efficiency IE5+ synchronous motors. The CFC open-loop injection method supports 150% overload starting, achieving more dynamic acceleration through short ramp times. This method maintains high energy efficiency, especially in the partial load range, and reduces material and installation costs by eliminating the need for an encoder.
The new modular system gives users more flexibility during design. Thanks to functional consistency, users can freely choose between motor-mounted or wall-mounted frequency inverters based on their requirements. The integrated functions reduce wiring effort, simplifying installation and maintenance. Overall, with this solution, NORD achieves a cleaner, more streamlined system architecture and extends the performance range.
