Product Description:

The AX2513-B750-0000 is a single-axis servo drive produced by Beckhoff and listed in the AX Digital Servo Drives series. It links the machine controller to a synchronous or induction motor, converting DC bus energy into a variable AC waveform so commanded speed and torque are followed precisely. In industrial automation, the unit occupies the same role as larger cabinet drives but is sized for compact cells, pick-and-place modules, and material-handling stations that require deterministic motion with limited enclosure depth. Because it controls one motor channel at a time, it suits machines that assign separate motion tasks to individual axes.

It delivers a continuous phase current of 3 A rms and can supply brief surges up to 9 A rms during acceleration. A pulse-width-modulated inverter operates at 8 kHz, keeping current ripple low while containing switching loss. Protection is aided by an overvoltage shut-off threshold of 750 V that isolates the DC link when regenerated energy rises excessively. For analog velocity or torque commands, the differential input resolves 1.25 mV steps across its 20 kΩ impedance, giving external PLCs fine adjustment range. Auxiliary rails for back-to-back and ramp-to-operate functions furnish 0.5 A for control loads, and the logic section idles at 12 W of quiescent dissipation, easing cabinet heat budgeting. This arrangement supports smooth response when the application shifts between steady motion, positioning moves, and short acceleration periods.

Upstream feeders can be sized for 12 kVA of installed load, matching conveyor or spindle groups driven from a shared DC bus. The current loop remains stable with motor inductances between 12 mH and 75 mH, allowing connection to both low-inertia servos and higher-inductance machines without retuning. Under rated output, the heat sink releases 35 W, managed by free convection through a 100 mm wide, 240 mm deep, and 230 mm high aluminum enclosure. The 3 kg mass supports DIN rail or panel installation next to I/O terminals, and the compact housing helps preserve usable cabinet space for wiring and adjacent control hardware. This operating range gives the power stage flexibility when it is paired with different motor types in the same machine platform.
