AX5203-0000-0202 by Beckhoff

The AX5203-0000-0202 is a two-channel servo drive produced by Beckhoff within the AX Digital Servo Drives series. It converts fixed-frequency mains power into controlled output that synchronizes the torque, speed, and position of matched servo motors in automated machinery. By combining internal braking circuitry with a shared DC link, the unit manages regenerative energy and helps machine builders minimize external components while maintaining a fast dynamic response in multi-axis applications.

The power stage can deliver a nominal phase current of 3 A and tolerate short-term demands up to 10 A during acceleration peaks. Energy is buffered by a DC link rated at 875 VDC, and its storage capacity of 470 µF smooths voltage ripple when several axes draw current simultaneously. The input section accepts line supplies at 50/60 Hz, so the unit can be installed worldwide without altering the control topology. A continuous brake power rating of 150 W dissipates routine regenerative energy, while internal and external brake channels handle peak loads of 14 kW and 15 kW, respectively. These brake channels allow the drive to absorb rapid deceleration bursts without triggering fault thresholds.

Mechanical and safety parameters support the drive's integration into industrial control systems. The enclosure carries an IP20 rating, indicating finger-safe terminals suited for installation inside a switch cabinet. The overall height is 317.70 mm, the width is 92 mm, and the depth is 232 mm, allowing the device to fit standard 300 mm control panels with room for airflow. The short-circuit current rating is 18 kA, and the electronics limit the combined device current to a total peak of 20 A. A minimum brake resistance of 47 ? must be maintained to keep heat dissipation within the permitted thermal range.
