Product Description:

The AX5112-0000 is a digital servo drive manufactured by Beckhoff and supplied within the AX Digital Servo Drives series. It interfaces between a motion controller and a synchronous or asynchronous motor, delivering regulated current and voltage so that closed-loop positioning tasks in automated machinery can be executed with millisecond accuracy. By integrating power electronics and a DC link in a single housing, the unit simplifies cabinet layouts while supporting regenerative energy management across multi-axis systems.

The drive supplies up to 8.3 kVA of apparent power from a 400 V AC mains supply and sustains a nominal motor current of 12 A. During acceleration or shock loads, it can reach a peak output of 26 A without violating thermal limits. Its DC link is rated for a maximum of 875 VDC and is buffered by a 1175 µF capacitor bank that smooths bus ripple and stores regenerative energy. Current control is processed at full resolution, allowing fine torque modulation. Internal power dissipation is limited to 160 W during continuous operation, and the electronics are protected against overvoltage by an active brake chopper. Cabinet space is reduced with a width of 92 mm, a depth of 232 mm excluding connectors, and a height of 317.2 mm.

For kinetic energy management, the AX5112 includes a continuous brake channel rated at 90 W and can momentarily absorb up to 26 kW with its internal resistor. When regeneration exceeds that level, an external resistor of at least 30 Ω may be added to provide additional braking capacity. The housing’s front profile of 92 mm simplifies side-by-side mounting, while the depth accommodates rear cable bends. Aggregate power loss and the forced-air cooling path keep semiconductor junctions within their allowable temperature range during operation.
