With the NORDAC PRO SK 500P, NORD DRIVESYSTEMS possesses a control cabinet inverter for virtually every drive application. It is available in variants with a power range of 0.25 to 22 kW, which can be assigned to different requirements in different industries. At present, the system supplier is working to extend the power range.

A control standard across several applications – the objective NORD has set itself when developing the NORDAC PRO SK 500P. The result is a control cabinet inverter, whose features allow for a high level of versatility and intelligent communication with system components. This way, NORD users can reduce the number of inverter variants and rely on a system in the long term.

Versatile integration
As with all NORDAC PRO inverters, the integrated multi-protocol Ethernet interface is one of the key elements. It can be used to integrate the control component into different networks without retrofitting. This includes the Profinet, EtherCAT, EtherNet/IP and POWERLINK protocols. Further protocols are covered depending on the model. A USB interface also allows for the voltage-free parameterisation of the inverter.

The integrated PLC responds independently to process changes in the system. It can thus relieve the load on the higher-level control. The POSICON positioning function implements various positioning tasks. It is equally able to control relative or absolute positioning using incremental or absolute encoders. Parameter set switching even allows for the sequential positioning of up to four axes.

Control of devices from lifting gear to pumps
With NORDAC PRO SK 500P, users can implement a wide range of industry-specific drive applications. The control cabinet inverter has a vector regulation with an overload reserve of 200%. It is thus suitable for the control of geared motors in heavy-duty applications or lifting systems. Its PI controller and its integrated compensator control makes it the suitable frequency inverter for pumps and winding systems. At the same time, the frequency inverter in its book-size format requires very little space in the control cabinet and allows for direct side-by-side installation without gaps.

More sizes in preparation
With NORDAC PRO SK 500P, it is possible to control all motor types with and without encoder feedback. To make its advantages available in a wider power range, NORD currently works on new sizes for the inverter.

In combination with geared motors, industrial gear units and electric motors from the NORD modular system, this results in drive solutions, which are technically and economically designed for the respective application requirements. NORD supplies them completely from a single source. For this, the system supplier can rely on a global network of more than 80 countries.

Company background
With approx. 4,800 employees today, NORD DRIVESYSTEMS has developed, produced and sold drive technology since 1965, and is one of the leading global full-service providers in the industry. In addition to standard drives, NORD delivers application-specific concepts and solutions for special requirements such as energy-saving drives or explosion-protected systems. In the 2023 financial year, annual sales amounted to € 1.09 billion. NORD has 48 subsidiaries in 36 countries and further sales partners in more than 50 countries. They provide technical support, local stocks, assembly centres and customer service. NORD develops and produces a wide range of drive solutions for more than 100 industries, gear units for torques from 10 Nm up to over 282 kNm, supplies electric motors in the power range of 0.12 kW to 1,000 kW, and supplies the required power electronics with frequency inverters of up to 160 kW. Inverter solutions are available for conventional control cabinet installations as well as for decentralised, fully integrated drive units.
