Product Description:
The AX5203-0000-0202 is a dual-axis drive module produced by Beckhoff for the AX Digital Servo Drives series. It operates on a common DC bus and exchanges energy with adjacent inverters to minimize power loss. By switching insulated-gate transistors in synchronization with encoder feedback, the device supplies variable voltage and frequency to two servo motors. This control loop allows machinery to achieve precise position, speed, and torque regulation without the mechanical complexity of gear-based regulation.
Each channel of the drive can deliver a nominal phase current of 3 A, providing continuous torque production for medium-frame servo motors. During acceleration or shock loading, the current rises momentarily to 10 A, providing reserve torque while keeping the semiconductor stages within their operating limits. The DC link that feeds these output stages is stabilized by 470 µF of capacitance, which dampens voltage ripple when regenerative energy returns from the motor. The link voltage must remain below 875 VDC to protect the electrolytic capacitor bank from electrical overstress. Mains power is accepted at 50/60 Hz, allowing the unit to operate with European or North American three-phase power systems. The common bus architecture also allows regenerated energy from one decelerating axis to support another axis that is accelerating.
The internal braking resistor can absorb up to 14 kW of peak regenerative power during deceleration. Terminals also support an external resistor rated at 15 kW when loads with greater inertia must be stopped. For continuous duty, the braking circuit is limited to 150 W, so external braking hardware should be selected according to the frequency and duration of braking cycles. Safe energy dissipation requires a minimum resistance of 47 Ω. The housing measures 92 mm wide, 232 mm deep, and 317.70 mm high, providing dimensions suitable for installation in an industrial control cabinet. The IP20 enclosure protects against accidental contact with hazardous internal components but requires installation in a suitable panel. Its short-circuit current rating is 18 kA, which is compatible with the fault-current levels found in typical industrial electrical systems.
