NORDAC PRO SK 500P VFDs

High performance in the control cabinet: The NORDAC PRO SK 500P variable frequency drives are equipped with an integrated multi-protocol Ethernet interface, multi-encoder interface for multiple-axis operation, and USB interface for voltage-free parameterization.

Cabinet-mounted variable frequency drives from NORD cover rated motor powers from 0.33 to 30 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.

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.

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 that 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.

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, and 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.
