AX5160-0000-0200 by Beckhoff

The AX5160-0000-0200 is supplied by Beckhoff within the AX Digital Servo Drives series. It interfaces with a central motion controller to energize three-phase motors, shaping the DC-link voltage into pulse-width-modulated outputs that generate commanded torque and velocity in industrial automation cells. Integrated braking circuitry allows kinetic energy from decelerating axes to be redirected to external resistors instead of returning it to the mains.

The drive delivers apparent power levels of 42 kVA at 400 V AC and 45 kVA when operated with a 480 V AC supply. A DC-link capacitor bank rated at 900 µF stabilizes the intermediate circuit against load transients, while an internal current path tolerates a nominal motor load of 60 A and accommodates peaks up to 120 A for rapid acceleration profiles. The minimum continuous motor current starts at 16 A to ensure reliable current measurement accuracy. Protective logic monitors the link voltage and coordinates with a short-circuit current rating of 5 kA, while normal conversion losses are limited to 830 W to simplify enclosure cooling. The housing has a depth of 259 mm without connectors, permitting side-by-side mounting on standard control cabinet backplates.

The braking module can dissipate up to 52 kW of instantaneous power and supports a continuous rating of 37 kW when paired with a resistor of at least 13 ?. DC-link supervision trips if the bus voltage rises above 875 VDC, and a mandatory 15-minute discharge period must elapse before maintenance access. The enclosure is 345 mm tall and 190 mm wide, keeping heat paths short and allowing vertical alignment with other AX units. Its proportions also preserve access to the electrical connections when multiple drive modules are installed in the same control cabinet.
