Product Description:

The AX5106-0000-0020 digital servo drive is manufactured by Beckhoff as part of the AX Digital Servo Drives series. It regulates the current and voltage supplied to synchronous or induction servomotors, enabling precise speed and torque control in automated machinery. The unit communicates with the machine controller to execute position, velocity, and torque commands while safeguarding both the motor and the connected power system.

With a three-phase 400 V mains supply, the drive can deliver an apparent power of 4.2 kVA, supplying sufficient energy for medium-frame servomotors in packaging, material-handling, or assembly cells. When only a single-phase 230 V supply is available, its usable apparent power is limited to 1.8 kVA, allowing operation on smaller test benches while retaining full control functionality. The continuous output capability on a three-phase circuit is 6 A, while short surges of up to 13 A accommodate rapid acceleration or regenerative peaks. A reinforced DC-link section withstands up to 875 VDC, providing headroom against line fluctuations and back EMF from high-speed deceleration.

Energy returned from motor braking is buffered by a DC-bus capacitor rated at 235 µF; this reduces voltage spikes before excess energy is dissipated. An integrated resistor absorbs up to 150 W of braking power, and the drive supports an external brake resistor rated for up to 15 kW under heavier cyclic loads. To protect this external network, the unit will not connect to a resistor with a resistance below 47 Ω, preventing overcurrent faults. Eight programmable digital inputs accept status or limit contacts to coordinate these functions. The housing measures 185 mm by 232 mm by 317.7 mm and transfers 85 W of internal losses to the cabinet airflow without additional fans.
