Product Description:
The AX2516-B200 is a digital servo drive produced by Beckhoff as part of the AX Digital Servo Drives series. Intended for closed-loop motion control in industrial automation, it converts the DC link voltage of a multi-axis power supply into three-phase output that synchronizes motor speed and torque with the command profile. The drive incorporates an add-on fan for convective cooling, which permits continuous operation inside control cabinets without external airflow management.
The drive accepts position or velocity commands over the Beckhoff Lightbus fieldbus and reproduces them with an output stage that pulses at 8 kHz, limiting current ripple in the motor windings. The hardware can furnish up to 12 A rms for short periods to overcome inertia during rapid indexing, and power losses at rated load amount to 60 W. A quiescent dissipation of 15 W is recorded when the axes remain enabled but unloaded. An enclosure protection rating of IP20 allows mounting inside electrical cabinets where contact with live parts is prevented but airflow is still possible. The permissible load inductance spans 7.5 mH to 40 mH, letting the unit pair with a wide range of motor windings without destabilizing the current regulator.
The housing measures 100 mm in width, 240 mm in depth, and 267 mm in height, occupying minimal rail space for a drive that supports an installed load of 12 kVA on the shared DC bus. Total mass is 3 kg, which simplifies panel assembly and reduces cantilever forces on DIN hardware. The continuous output channel is rated at 6 A rms, giving a reference for motor cable sizing and thermal trip selection. Transient energy on the DC link is capped by an overvoltage shutdown set at 750 V, protecting internal IGBTs and connected equipment.
