Product Description:

Beckhoff’s AX2513-B750 belongs to the AX Digital Servo Drives series and serves as a compact drive controller for single-axis motion. The manufacturer integrates the power electronics, current measurement, and communication layers so the module can deliver vector-controlled voltage to a servo motor while exchanging real-time data with the machine PLC through its SERCOS interface. In an automated line, the drive regulates motor torque, velocity, and position, forming the link between the low-level feedback loops inside the cabinet and the mechanical load on the machine.

The internal control loops are clocked at 8 kHz, allowing rapid current regulation cycles that minimize overshoot in dynamic positioning tasks. A maximum installed load of 12 kVA is the highest apparent power the unit should process without exceeding thermal limits. For short acceleration bursts, the inverter can supply a peak phase current of 9 A, a value matched to motors whose winding resistance and back EMF demand high startup torque. Motor windings up to 75 mH of inductance can be driven without destabilizing the current controller, and the output current form factor is kept to 1.01 so RMS and average values remain almost identical, reducing copper losses during continuous operation.

The continuous phase current is 3 A, aligning the drive with low-to-medium inertia servomotors that operate for long periods at nominal load. Protection circuitry disconnects the DC bus when the intermediate circuit exceeds 750 V, guarding downstream insulation systems during mains transients. At full load, the unit releases only 35 W as heat, and its aluminum housing weighs 3 kg. The housing mounts on a 100 mm wide rail and measures 230 mm in height and 240 mm in depth. Additional data include a minimum permissible load inductance of 12 mH, quiescent dissipation of 12 W, and conformity with the IEC 61491 SERCOS standard.
