The all-rounder: NORDAC PRO control cabinet inverter

Thanks to its versatile interfaces, the NORDAC PRO frequency inverter from NORD DRIVESYSTEMS can be easily integrated into automation environments. As a control centre between control and axis motion, it provides optimum control of the drive and peripherals.

Precise motor control for asynchronous and synchronous motors, with and without encoder feedback, guarantees a high overload capacity of up to 200% and stable, load-independent speed as well as dynamic starting/stopping. These are all features of the NORDAC PRO SK 500P control cabinet inverter from NORD. The integrated POSICON function allows movement to numerous absolute positions or incremental feed along endless-loop axes. Movements of several drives that are synchronised along the same axis can be easily achieved using on-board functions; sequential control of several axes including encoder evaluation, for example in warehouse systems, can also be implemented.

One inverter series as standard

The NORDAC PRO SK 500P can be used as a control centre for numerous drive applications, including lifting gear thanks to overloads up to 200%, pumps thanks to PI control or dynamic applications thanks to encoderless CFC open-loop injection control. Using the NORDAC PRO SK 500P as the standard in the control cabinet reduces procurement and storage effort while also minimising the range of spare parts.

Space-saving installation, ready to use in no time

Four Industrial Ethernet dialects can be selected via the multi-protocol Ethernet interface of the control cabinet inverter: Profinet, EtherNet/IP, EtherCAT, POWERLINK. The integrated PLC of the NORDAC PRO SK 500P acts as a soft PLC, handling drive-related functions, reducing the load on the main PLC or replacing smaller PLCs. The result: faster commissioning of machines and systems, with less wiring, installation and maintenance effort.

Thanks to its compact design, the frequency inverter saves space in the control cabinet: the NORDAC PRO SK 500P is available in book-size format up to a power class of 22 kW. Depending on the system architecture, the integrated functions eliminate the need for previously required slots in the control cabinet, for previously required additional control cabinets or even for the higher-level PLC.

Scalable for various applications

The NORDAC PRO family comprises three configuration packages that users can tailor to the requirements of the respective application. NORD offers the NORDAC PRO as a machine inverter for standard applications or as an application inverter in two variants for networked drive applications.
