Product Description:

The AX2090-MD50-0025 motor cable is produced by Beckhoff and belongs to the AX Digital Servo Drives series. It functions as the dedicated power connection between an AX servo drive and its synchronous servomotor in industrial automation cells. By providing a matched conductor cross-section, shielding, and strain relief for the drive output, the cable supports repeatable torque commands, fast current rises, and reliable protective earth routing. Integrating this component reduces wiring variation on assembly lines that use multi-axis packaging, pick-and-place, or material-handling equipment.

Electrical performance is based on a nominal operating voltage of 480 V AC, allowing the assembly to handle the three-phase mains used by the AX drive rectifier. A continuous thermal current capacity of 25 A supports sustained motor loads without exceeding the 50 °C rating of the jacket. The conductor inductance is 0.12 mH, which keeps reactive impedance low so the drive can apply high-frequency switching without excessive voltage overshoot. Insulation integrity is verified through a cable-to-cable test at 1770 V DC and a cable-to-housing test at 2700 V DC. These insulation tests check the separation between conductors and grounded parts during high-voltage stress.

The assembly can be routed up to 50 m between the drive and motor, while system resonance control requires at least 25 m of cable length. A loop resistance of 15 mΩ minimizes voltage drop and helps maintain servo stiffness during acceleration. The cable weighs 8.5 kg, which suits dynamic cable tracks while still providing a durable outer structure. This length and resistance combination supports stable power delivery during continuous axis movement in automated machinery.
