New control cabinet inverters from Nord Drive Systems
Nord Drive Systems is introducing NORDAC PRO SK 500P frequency inverters. They 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. These new control cabinet inverters cover rated motor powers from 0.25 to 5.5kW and, according to Nord, feature high levels of connectivity, functionality and versatility. Various device versions are available and offer pug-in control, safety and option modules ensure flexibility. What Nord refers to as "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: Profinet, EtherNet/IP, Powerlink or EtherCAT protocols can be set. Nord points out that the future-proof nature of its 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 the parameterisation of the inverter when the power is switched off. It also provides a CANopen interface, five or six digital plus two analogue inputs, two digital and one analogue 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 out up to four encoder systems simultaneously and can thus control several motors in positioning mode. Other features highlighted include an integrated PLC for motor-related motion and logic control, a 200 per cent overload reserve for torque and speed performance as well as sensorless current vector control for asynchronous and synchronous motors (both open and closed loop). The integrated brake chopper for 4-quadrant operation is a part of the basic equipment across the entire series, as is motor brake management. NORD supplies the inverters with integrated STO and SS1. The integrated PLC processes the data from sensors and actuators and can autonomously initiate control sequences, as well as communicating drive and application data to a control centre, networked components or to cloud storage. This allows continuous condition monitoring and therefore forms the basis for predictive maintenance programmes.
