Product Description:

The AX5112-0000-0210 is a single-axis digital servo drive produced by Beckhoff in the AX Digital Servo Drives series. It sits between a machine controller and a synchronous or induction motor, regulating current, voltage, and braking energy so that automated axes follow commanded positions and speeds. As a single-channel unit, it simplifies cabinet layouts in assembly lines. The second-generation design also suits EtherCAT-based control architectures used in automated equipment where precise axis coordination is required.

The drive supplies a nominal output current of 12 A, which is the continuous motor phase current it can regulate without exceeding thermal limits. For short acceleration bursts, it can deliver a peak output current of 26 A, allowing the connected axis to overcome inertia or friction without requiring an oversized frame. A DC link designed for up to 875 VDC stores energy in a 1175 µF capacitor bank; the elevated voltage raises power density, while the capacitance smooths regenerative surges from motor deceleration. During steady dynamic operation, the integrated brake chopper dissipates up to 90 W of continuous braking power, keeping the link voltage within limits. Internal current sensing and the single-channel power stage support stable torque control for one motor.

When larger regenerative loads are expected, an external resistor of at least 30 Ω can be wired so the unit dissipates up to 23.5 kW continuously and withstands 26 kW during short peaks. Even under full load, the internal electronics lose only 160 W, which helps reduce heat inside an enclosure, and the housing has a protection rating of IP20. The mechanical package measures 185 mm in width, 317.70 mm in height, and 232 mm in depth without connectors. These dimensions allow dense mounting while still leaving space for airflow around adjacent modules and for orderly cable routing inside the cabinet.
