AX2513-B900 by Beckhoff

The AX2513-B900 is a single-axis servo drive module manufactured by Beckhoff as part of the AX Digital Servo Drives series. It interfaces between a motion controller and a synchronous or asynchronous motor, generating three-phase output currents from the shared DC bus to position axes in packaging lines, material-handling systems, and pick-and-place cells. By combining current regulation and integrated brake control, the drive delivers closed-loop torque, velocity, and position control inside a compact panel-mount package.

The drive supplies a continuous motor current of 3 A and can support bursts up to 9 A for rapid acceleration events. The design tolerates load inductances from 12 mH to 75 mH, allowing it to pair with both low-impedance and highly inductive windings without instability. Internal protection disconnects the DC link when the bus rises to 750 V, preventing damage from regenerative surges. Power loss is 35 W at the rated current, while standby operation draws only 12 W. Motor holding brakes can be driven directly, and the dedicated 1.5 A brake output is switched with the enable signal. The analog command channel is refreshed every 62.5 µs, so external process values are accepted without noticeable latency.

The analog interface has an input impedance of 20 k?, limiting source loading, and each sample has a resolution of 1.25 mV so fine position or pressure references are preserved. Current loops and encoder processing operate at 8 kHz, providing eight thousand updates per second for phase-aligned modulation. The housing occupies 100 mm of panel width, extends 240 mm into the enclosure, and stands 230 mm high. Its weight of 3 kg keeps mechanical stress low on mounting rails and supporting panel structures. The compact dimensions leave room for adjacent drive modules while allowing suitable cable routing and ventilation clearances. The stated power loss helps determine the airflow needed to remove heat from the enclosure during continuous operation.
