Product Description:
The AX2090-NF50-0014 is a drive cable produced by Beckhoff for use with the AX Digital Servo Drives series. Its role in industrial automation is to transmit regulated output power from the servo amplifier to the motor over a very short distance, which helps limit voltage drop and reduce electromagnetic interference inside control enclosures. The cable includes a preassembled grounding lead and shielding structure, so cabinet wiring can be kept orderly while maintaining a reliable ground path between connected components.
The conductor system has a nominal voltage rating of 480 VAC, allowing direct connection to the drive’s three-phase output stages without additional transformers. A continuous load capacity of 14.6 A supports medium-power axes that draw peak currents only briefly during acceleration and deceleration. The assembly is suitable for systems operating at 50 / 60 Hz, matching common plant power standards. DC loop resistance is limited to 9 mΩ, so heating losses across the short cable run stay low and drive current control remains stable. For insulation verification, the cable withstands a cable-to-cable test potential of 2236 VDC, confirming dielectric strength between adjacent conductors during high-voltage testing.
Additional insulation strength is provided by a cable-to-housing withstand voltage of 2720 VDC, which helps protect against unintended contact between live conductors and the metallic connector shell. The conductor cross-section is 4 mm², balancing flexibility with current-carrying capacity in space-restricted machine compartments. Under steady-state conditions, the assembly contributes a leakage current of 15 mA, a value suited to the monitoring functions used in compatible drive systems. Application layout is also simplified by the maximum permissible drive-to-motor distance of 0.4 m, making the cable appropriate for tightly integrated installations where the motor is mounted directly beside the amplifier.
