Nord Drivesystems introduced its NORDAC PRO SK 500P cabinet mounted variable frequency drives covering rated motor powers from 0.33 to 7.5 HP.
These variable frequency drives feature an integrated multi-protocol Ethernet interface, multi-encoder interface for multiple axis operation, and USB interface for voltage-free parameterization.
The Ethernet interface 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.
Connectivity includes 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 that 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. They also feature 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).
The integrated PLC 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.
