NORD Introduces High Connectivity Variable Frequency Drives

The NORDAC PRO SK 500P variable frequency drives from NORD DRIVESYSTEMS are equipped with an integrated multi-protocol Ethernet interface, multi-encoder interface for multiple axis operation, and USB interface for voltage-free parameterization.

NORDAC PRO SK 500P: The new NORDAC PRO family cabinet mounted variable frequency drives provide high levels of connectivity, functionality, and modularity.

The newest cabinet mounted variable frequency drives from NORD cover rated motor powers from 0.33 to 7.5 hp and feature ultimate levels of connectivity, functionality, and versatility. With a wide range of customization options, these units can be tailored to most application requirements. Additionally, plug-in control, safety, and option modules ensure maximum flexibility and the compact book-size design enables space-saving installation in control cabinets.

Integrated multi-protocol Ethernet interface NORDAC PRO SK 500P is the new generation of cabinet mounted VFDs. The series is equipped with an integrated universal Ethernet interface that enables the use of major real-time Ethernet standards via one single interface. Whether for PROFINET, EtherNet/IP, POWERLINK, or EtherCAT, the required protocol can be easily set via parameters.

Voltage-free parameterization via USB port The future-ready nature of the 500P modular series is shown by its modern connectivity, including the use of an SD memory card as a storage medium for parameters, and a USB interface which enables (in the box) parameterization of the VFD when the power is switched off. It also provides a CANopen interface, five or six digital and two analog inputs, two digital and one analog output, two potential-free multi-function relays, an HTL/TTL incremental encoder interface, as well as a universal encoder interface which enables connection of SIN/COS, BiSS SSI, Hiperface, and EnDat encoders.

Multi-encoder interface for multiple axis operation The NORDAC PRO SK 500P can read up to four encoder systems simultaneously and can control several motors in positioning mode. Together with features such as an integrated PLC for motor-related motion and logic control, a 200% overload reserve for perfect torque, speed performance, and sensorless current vector control for asynchronous and synchronous motors (open-loop and closed-loop), it is a genuine all-around control solution. The integrated brake chopper for 4-quadrant operation is standard for the entire series, as is motor brake management, which is especially important for lifting gear applications. NORD supplies all 500P variable frequency drives with integrated STO and SS1.

The integrated PLC of the NORDAC 500P processes data from sensors and actuators and can autonomously initiate control sequences, as well as communicate drive and application data to a control center, networked components, or cloud storage. This allows continuous condition monitoring and forms the basis for predictive maintenance concepts as well as optimizing plant dimensioning.

Intelligent, communicative, and easy to connect: With the NORDAC PRO SK 500P, the NORD DRIVESYSTEMS range includes future-proof, user-friendly VFDs for control cabinets. The overall concept has been revised so that the 500P series provides a future-proof platform that ensures many years of power and performance from NORD. The new series is also downward compatible with the current SK 500E series.
