Product Description:

The AX2516-B900 is a digital servo drive produced by Beckhoff within the AX Digital Servo Drives series. It supplies controlled three-phase power to synchronous or induction motors, enabling precise speed and torque regulation in automated machinery, packaging stations, and material-handling axes. Its control architecture supports responsive motor operation in positioning systems and other repeatable motion tasks where stable drive output is important.

The drive delivers a continuous phase current of 6 A RMS and can reach a short-term peak of 12 A RMS for acceleration or impact loads. A DC-bus overvoltage trip point of 750 V protects internal components when regenerated energy raises bus voltage beyond safe limits. An output current form factor of 1.01 indicates that the sinusoidal current delivered to the motor is almost free of harmonic distortion, promoting low motor heating. Thermal behavior is characterized by only 60 W of power loss at rated current, while standby operation draws 15 W, allowing efficient cabinet cooling design. The unit can handle an S1 installed load of 12 kVA and remains stable with load inductances between 7.5 mH and 40 mH, so both low-inertia and highly inductive motors can be connected without risking current loop oscillation.

The housing meets IP20, so it must be mounted in a control cabinet while still allowing access to the terminals. Motor leads up to 25 m are supported without exceeding the specified leakage current limits, which helps with machine layouts that place motors away from the drive cabinet. A compact form factor of 100 mm wide, 267 mm high, and 240 mm deep, together with a 3 kg mass, simplifies installation on DIN rails or backplates. Acoustic output stays below 45 dB(A), helping the surrounding workspace remain quieter during operation. The stated dissipation values also help airflow planning when several modules are mounted next to one another.
