8400 TopLine inverter drives integrate seamlessly with servo technology

Lenze has designed a bus for easy communication between axes

Hameln/Nuremberg, (PresseBox) - For communication between the axes of the 8400 TopLine inverter drives, Lenze has added an axis bus to their functions, as well as special function blocks for speed and angle synchronisation. It works independently of, and in parallel with, the CAN system bus which is part of the standard equipment. This further development is primarily intended for the creation of electrical shafts for synchronisation. The 8400 TopLine thus fits seamlessly into the typical applications of servo technology. Other functions of the 8400 TopLine typical of servo technology are the support of SinCos absolute encoders (Hiperface®) and SinCos encoders.

The advantages of the axis bus result, to a large extent, from the simplicity of configuration, the easier construction of lines and cascades, and the optimum exploitation of the bus bandwidth through synchronisation at the hardware level. Two fundamental topologies can be constructed using the automatic axis bus system. In the first case, all drives in the network are connected to the higher-level master controller. For their part, the axes exchange data between themselves. An architecture in which only one axis bus master acts as the link to the controller, on the other hand, is appropriate when the controller only needs to supply a small amount of information to the group of axes.
