AX5101-0000-0200 by Beckhoff

The AX5101-0000-0200 is a single-axis digital servo drive produced by Beckhoff for the AX Digital Servo Drives series. Designed for cabinet installation, it occupies a compact width of 92 mm, stands 317.70 mm high, and has a depth of 232 mm, allowing multiple drives to be installed side by side in standard control panels. Within an automation cell, the unit interfaces with EtherCAT motion controllers to regulate motor voltage and current, providing precise torque, velocity, and position control for packaging machines, gantries, and assembly stations.

With a 400 V AC supply, the drive can deliver an apparent power of 1.0 kVA, supporting a continuous motor phase current of 1.5 A and short-term surges of up to 4.5 A during rapid acceleration. The channel remains controllable down to a minimum peak current of 0.35 A, which supports the operation of smaller motors on the same drive platform. Current regulation is refreshed every 62.5 µs within the velocity loop, while fieldbus and terminal signals are updated every 250 µs, allowing close synchronization with high-speed machine cycles. A DC-link capacitor with a capacitance of 235 µF stabilizes the intermediate circuit. A 47 ? external brake resistor can be connected to dissipate regenerated energy without overstressing the internal bus.

The drive has a core power loss of 35 W, which must be considered when determining cabinet ventilation requirements. The integrated chopper supports 50 W of continuous braking power, helping control DC-link voltage during routine deceleration. When heavier axes are connected, the external brake terminal can route up to 15 kW to a suitably sized resistor. The bus voltage can rise to 875 VDC without triggering an overvoltage fault. The electronics are housed in an IP20 enclosure, which protects against finger contact and the entry of solid objects larger than the applicable protection threshold when the drive is installed inside a closed electrical cabinet.
