Machine tool element control device

摘要

The control device has at least one controller area network bus (1,2) connected to each of the controlled elements of the machine tool, for providing the data for controlling the latter. The controller area network bus has at least one bus coupling element (3,4) for connection to a peripheral device (5) via an optical transmission path (8), providing electrical separation. The bus may include an amplifier for compensating the light losses within the bus before the bus coupling element connected to the peripheral device.
