Product Description:
The AX2523-B510 is a two-channel servo amplifier from Beckhoff in the AX Digital Servo Drives series. As a drive controller, it conditions DC bus energy and regulates current for synchronous and induction servomotors used in positioning, packaging, and assembly lines. The unit accepts ±10 V analog command signals and can also be paired with fieldbus interfaces, giving PLCs deterministic access to the power stage. By keeping torque loop processing inside the module, the drive offloads the motion controller and supports repeatable axis response during speed and position changes. That combination allows the amplifier to serve both straightforward analog control schemes and more integrated automation architectures.
At the analog front end, the reference range is ±10 V, buffered by an input resistance of 20 kΩ so command sources see a defined load. The converter samples that signal at a resolution of 1.25 mV every 62.5 µs, supporting fine torque steps for tight loops. An 8 kHz output-stage clock drives the IGBTs, balancing acoustic noise and switching loss. Continuous phase current is 3 A, with peak bursts to 9 A for acceleration. Under rated operation, the bridge dissipates 30 W, and the quiescent electronics add 12 W that must be included in cabinet cooling. A current form factor of 1.01 keeps RMS and average values nearly equal. The amplifier accepts motor inductances from 12 mH to 75 mH.
Integration in a control cabinet is simplified by the 240 mm depth, 50 mm width, and 230 mm height, allowing two drives to share a 100 mm rail without crowding wiring ducts. The narrow housing also leaves room for adjacent wiring ducts in dense panels. Total mass is 1.7 kg, which keeps handling manageable while remaining stable once fixed to the panel. Side vents guide forced air across the internal heat sink, and front docking connectors keep cables inside the footprint. This layout helps preserve front access and supports compact multi-axis cabinet arrangements.
