Product Description:
The AX5721-0000 is a single-axis drive module from Beckhoff that belongs to the AX Digital Servo Drives series. It links the DC bus to a servomotor, shaping current while reading encoder data to execute precise motion tasks. EtherCAT integration lets the module fit directly into coordinated automation such as packaging, assembly, and material-handling lines. A compact housing permits dense panel layouts without sacrificing continuous-duty thermal performance. Its role in the control cabinet is to provide responsive axis control while staying compatible with distributed machine architectures that rely on fast cyclic communication.
Six additional digital inputs give the drive flexible event handling; the number is 6. Control electronics are powered by an auxiliary supply of 12 VDC, so diagnostics remain active when the power stage is disabled. Encoders are supplied from a regulated line of 5 VDC ±10%, protecting sensor electronics from overvoltage. The integrated power stage can source up to 0.25 A on each low-voltage output and provides thermal monitoring to help prevent overload. Feedback compatibility covers BiSS mode C and EnDat version 2.2, enabling absolute rotary measurement with 32-bit single-turn and 16-bit multi-turn words that support fine interpolation during high-speed moves. A single servo drive channel is available for independent positioning duties, which suits machines that need one dedicated axis in a narrow installation space.
Beyond the primary port, the housing offers 1 additional encoder input to observe a secondary scale or motor-mounted sensor. Linear feedback can be acquired with 48 bits of single-turn resolution, resulting in very fine command steps over long strokes. Functional safety is implemented via the plug-on AX5805 module; in the delivered configuration, the available mode is STO only, which removes motor torque through redundant hardware paths. All control, feedback, and auxiliary lines terminate at a single 15-pin male D-sub, simplifying cable routing inside the cabinet. This connector arrangement keeps the interface compact and helps maintain orderly wiring where multiple axes are installed side by side.
