Customised control systems made in Sweden Lämneå Bruk AB, best known for its wire machinery equipment – from complete lines to single machines – has also been building control systems since the 1990s, including PLC controls, frequency inverters and operating terminals (HMIs), in its own workshop in Ljusfallshammar, Sweden. The company’s control systems can be used not only for Lämneå Bruk machines but also for equipment from other manufacturers.

PLC systems, HMIs and other electrical components, for both Lämneå Bruk’s and other manufacturers’ machines. In the case of outdated electronics failing, Lämneå Bruk has customised solutions available. Custom-built spare parts can maintain the electronics of mechanically operational machinery, to extend the cabinets’ lifetime. Lämneå Bruk recently carried out major investment in its electrical department. This included acquiring the ModCenter, which provides an automated solution for custom control panel builders. Drawings from the electrical planners are directly exported to the machine, eliminating the previous paper trail. Instead of manual measuring, drilling and taping, the ModCenter automatically produces perfectly aligned holes and cut-outs based on the drawing. This feature not only improves the quality and accuracy of

the panels, but also reduces machine lead times. The company has also invested in a wir- ing station that delivers the right wires in a fraction of the time compared to tradi - tional wiring, marks them, and prepares the wires’ ends. With the automated machine, the wires are cut to the right length and terminated. The operators acknowledge when all connections are done, and routed wire lists are saved in the system for future reference. Lämneå Bruk AB www.lamnea.se

Development in electronic equipment progresses constantly and rapidly, and often the technology utilised today is not compatible with older solutions. Lämneå Bruk recommends planning for system upgrades before a machine mal - functions and production is interrupted. The company can assist wire producers with upgrades for frequency inverters,
