AX5112-0000-0200 by Beckhoff

The AX5112-0000-0200 is a servo drive manufactured by Beckhoff for the AX Digital Servo Drives series. The unit operates as the power stage between a motion controller and a three-phase motor, translating low-level command signals into regulated current for precise torque and speed control. By supporting closed-loop positioning, it serves packaging axes, gantry carriages, and material-handling equipment that demand repeatable motion in industrial automation. Its design supports cabinet mounting alongside other drive modules.

At its continuous rating, the drive delivers 12 A of output current, while a short-duration peak of 26 A accommodates acceleration or sudden load changes. A configurable output setting down to 0.5 A allows the current to be matched to smaller motors. The DC link handles 875 VDC and stores energy in a 940 µF capacitor bank, providing voltage stability during regenerative events; a minimum external brake resistor of 30 ? can be connected when greater dissipation is required. Apparent power reaches 8.3 kVA on a 400 VAC supply, and the internal semiconductor design withstands fault currents up to 18 kA before protective trips occur. Sensor supplies rated at 1 A are available for encoder electronics, and overall power loss is limited to 160 W to control cabinet heating.

The drive integrates an internal brake chopper rated at 90 W, which supports routine deceleration of low-inertia axes without additional hardware. For high-energy stops, an external resistor network can absorb up to 23.5 kW, allowing machines to halt heavy loads without exceeding thermal limits. Eight opto-isolated digital inputs support functions such as enable, fast stop, and mode selection. The housing measures 92 mm wide, 232 mm deep, and 317.70 mm high, allowing the unit to fit into IEC 61439 control enclosures with standard air gaps.
