Configuration of the servo system

With a supply module and several axis modules, the servo drives of the AX8000 series offer optimum
functionality and cost-effectiveness. Integrated control technology supports fast and highly dynamic
positioning tasks. EtherCAT as a high-performance system communication enables ideal interfacing with PC-
based control technology.
The AX8000 system enables convenient and fast connection of the DC link of the supply module and several
axis modules via an AX Bridge. The connection can be established without tools through spring-loaded
terminals for DC link, control circuit and EtherCAT.
The AX8000 was developed specifically for the EtherCAT real-time Ethernet system. The outstanding
features of EtherCAT are particularly beneficial for drive technology. They include short cycle time,
synchronicity and simultaneity. EtherCAT enables very short cycle times, even in bus systems containing a
large number of devices.
The axis modules enable operation of motors with different ratings, thanks to scalable motor current
measurement. At an 8 A module the rated motor current can be set between 1 A and 8 A, without affecting
the quality of the resolution.
At a two-channel axis module two identical or two different motor versions can be connected. The total rated
current of the two motors is relevant for the choice of axis module. Note that the maximum current that can
be supplied at any one time is the rated current of the axis module.
