Product Description:

The AX5201-0000 digital servo drive is produced by Beckhoff as part of the AX Digital Servo Drives series. It acts as the power interface between a motion controller and servo motors, delivering regulated current for precise position and speed loops in industrial automation equipment. For cabinet layout, it occupies 92 mm in width, 317.70 mm in height, and 232 mm in depth without connectors, enabling high-density installation alongside other AX5xxx modules. Its format is suited to control cabinets where multiple motion axes must fit within limited panel space and share common airflow paths.

At rated conditions, the drive supplies a nominal phase current of 1.5 A per channel. Short-term demands up to 5 A accommodate motor acceleration. With a 230 V AC supply, the apparent power capability reaches 1.2 kVA, while on a 120 V line it is limited to 0.6 kVA. Energy is buffered by a DC-link capacitor bank totaling 235 µF, smoothing the rectified bus and absorbing regenerative surges. The link may climb to a maximum of 875 VDC, so cable insulation and terminal spacing must account for this potential. The hardware tolerates a minimum channel peak current of 0.35 A and records a nominal sum current of 3 A across its two outputs. The dual-channel layout supports two low-power motor connections from one housing in compact indexing or pick-and-place systems.

Continuous operation produces 55 W of losses that must be removed by cabinet airflow. The integrated brake chopper diverts up to 50 W of kinetic energy into an external resistor, and the resistor value must be at least 47 Ω to keep the chopper transistor within its duty cycle. During rapid reversals, the power stage can withstand momentary device currents of 10 A before overcurrent limits engage. This braking arrangement helps the drive absorb energy returned by decelerating loads during frequent starts and stops. Stable heat removal is important because dissipated losses and braking energy both affect module spacing inside the cabinet.
