NORD Drivesystems Profinet interface for SK 500E inverters

NORD Drivesystems supplies Profinet modules for the integration of frequency inverters into Profinet environments and has introduced modular units for cabinet-mounted SK 500E inverters while a version for distributed SK 200E-type inverters will follow.

With no need for repeaters or additional master interfaces, the NORD Profinet module is designed to cost-efficiently connect a large number of inverters to a single bus line. The unit supports real-time data transfer and features an integrated industrial ethernet switch, an integrated web server and a Profinet status display. Optionally, fibre-optic lines are also supported.

The bus module for distributed control can be mounted either directly on the inverter’s interface unit or separately from the inverter by means of an optional wall-mounting kit. The Profinet bus line is connected to the module via an RJ45 plug connector.

Optionally, for distributed control, the bus can be connected via an M12 circular connector. In addition, the module features eight integrated 24 V inputs and two 24 V outputs. With integrated gateway functionality, a single Profinet technology unit can address up to four inverters. An integrated RS232/RS485 interface allows for on-the-spot access to the parameters of the connected bus module and inverters by means of the SK PAR manual control unit or via Nordcon PC software. The distributed modules have a standard protection rating of IP55 and can be supplied for IP66 on request.
