Product Description:

The AX5101-0000-0200 is a single-axis digital servo drive produced by Beckhoff in the AX Digital Servo Drives series. It supplies controlled electrical power to brushless motors used in machining cells, pick-and-place stations, and other automated equipment. By combining current regulation, position control, and integrated brake handling in one housing, the unit serves as the direct interface between the machine controller and the motor.

With a 400 V mains connection, the drive has an apparent power rating of 1.0 kVA, providing the capacity needed to operate compatible motors. The current, velocity, and position loops are refreshed every 62.5 µs, keeping the following error low on fast axes, while field-level data are accepted at an I/O update interval of 250 µs. A DC-link capacitance of 235 µF smooths the rectified voltage and stores energy for brief acceleration bursts. The housing has an overall height of 317.70 mm, and sufficient clearance is required for ventilation at the top. Under a steady load, the power stage delivers a nominal motor current of 1.5 A. The peak current limit of 4.5 A accommodates brief torque demands without triggering overcurrent faults.

For braking energy management, the module can dissipate 50 W internally and works with external resistors rated at 47 Ω to absorb peaks of up to 15 kW. The intermediate circuit tolerates up to 875 V DC, providing headroom for supply fluctuations and regenerated energy during motor deceleration. Protection is rated at IP20, so the drive requires installation inside an enclosed panel with controlled cooling airflow. Total power loss is 35 W during nominal operation, while the minimum channel peak current of 0.35 A supports small feedback-controlled axes. The housing measures 92 mm wide and 232 mm deep, enabling multiple drives to be installed side by side on a common DC bus while preserving an orderly cabinet layout.
