In its cement plants and concrete factories in Croatia, geared motors of different performance classes are used. Heavy duty is no problem for the NORD products - they are ready for any challenge. That is why both companies have now completed a three-year-contract for the exchange of older drives.

SK 200E frequency inverters from NORD DRIVESYSTEMS are equipped with a proprietary system bus that allows for user-friendly, cost-efficient wiring in the field. Connected to the fieldbus or an Industrial Ethernet system via a bus technology unit that acts as a gateway, the system bus can link up to four frequency inverters. Thus, four drive units are connected to the higher-level communication system at one single point. All data is thus available at every diagnosis interface, i.e. users can access all data sets from every device connected to the system bus via RS232 interfaces at both the inverters and the technology unit.

In an extremely demanding construction project in the Swiss Alps, at an altitude of around 1700 metres and almost 600 metres inside a mountain, large chambers are being excavated to form the new expanded underground centre of a pumped storage hydroelectric power station that will increase its present power output from 480 MW to 1480 MW. With an extreme incline of 45 degrees and a height difference of approximately 180 m, conveyor systems in a sub-station are transporting 500 t of excavated material per hour, around the clock, using conveyor belts that are driven by NORD industrial gear units.

efficient frequency inverters implement precision and dynamics

SK 200E inverter series from NORD provides certified safety technology for applications up to SIL3

SK 200E series frequency inverters from NORD DRIVESYSTEMS provide solutions with adaptable functions for any application within a distributed automation concept where cost-efficient drives with a performance between 0.25 and 22 kW are required.
