Product Description:

The AX2513-B510 is a single-axis drive module produced by Beckhoff for the AX Digital Servo Drives series. It functions as the power and control interface between a motion controller and a synchronous or asynchronous servomotor, providing regulated current and voltage for precise position, speed, and torque control in industrial automation cells, packaging lines, and material-handling stations. The module is intended for closed-loop motion tasks that require stable response during dynamic changes in load and speed.

The command interface is analog, accepting a differential range of ±10 V with a 20 kΩ input resistance that minimizes loading on upstream signal cards. A resolution of 1.25 mV allows fine setpoint granularity, while the conversion is refreshed every 62.5 µs so the motor receives rapidly updated control data. Internally, the PWM clock runs at 8 kHz, which shapes the phase current into a near-sine waveform and keeps the specified 1.01 output current form factor. Drive enable is provided through a discrete input that expects 24 VDC, allowing the logic to gate power only when machine safety systems are satisfied. To protect the DC bus, the circuitry trips if link voltage exceeds 750 V, preventing damage to semiconductors during regenerative events.

The power stage delivers a peak phase current of 9 A rms for short acceleration bursts, while continuous operation is limited to 3 A rms so thermal limits are not exceeded. These currents suit motors whose line inductance lies between the specified 12 mH minimum and 75 mH maximum, helping current control remain stable. Heat produced under no-load conditions is 12 W of quiescent dissipation, rising to 35 W at rated current, so cabinet ventilation must accommodate that loss. Mechanical dimensions remain compact with a height, excluding plug-in connectors, of 230 mm. The aluminum housing, control board, and bus capacitors bring the total mass to 3 kg, which helps keep panel layouts compact.
