SIEMENS S.P.A.: An innovative steering system, Fahrlenksystem, that uses Simatic Micro-Drive, the universal Simatic controller and the new control software from Simove. The compact steering system features a special gearbox where the speeds of both motors in the steering system are overlaid. The steering system does not require moving cables. The result is 360-degree rotational movement of the wheel and therefore of the system. Due to the integrated safety functions of the Simatic Micro-Drive, safe control and monitoring of the integrated motors is ensured at all times.
