NORD Drivesystems NORDAC PRO SK 500P control cabinet inverters

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

The control cabinet inverters cover rated motor powers from 0.25 to 5.5 kW and feature high levels of connectivity, functionality and versatility. Various device versions can be optimally allocated to various application requirements. Plug-in control, safety and option modules ensure flexibility and the compact book-size design format enables space-saving installation in control cabinets.

The series is equipped with an integrated universal Ethernet interface that enables the use of the major real-time Ethernet standards via one single interface. Whether for Profinet, EtherNet/IP, Powerlink or EtherCAT, the required protocol can be easily set by means of parameters.

The futureproof nature of the modular series is shown by its modern connectivity, such as the use of an SD memory card as a storage medium for parameters, as well as a USB interface which enables ‘in the box’ parameterisation of the inverter 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 inverter can read out up to four encoder systems simultaneously and can therefore control several motors in positioning mode. Other features include the integrated PLC for motor-related motion and logic control, a 200% overload reserve for good torque and speed performance, and sensorless current vector control for asynchronous and synchronous motors (open loop and closed loop). The integrated brake chopper for 4-quadrant operation is a part of the basic equipment for the entire series, as is motor brake management. NORD supplies the inverters with integrated STO and SS1.
