AX5103-0000-0200 by Beckhoff

The AX5103-0000-0200 is a single-axis servo inverter produced by Beckhoff within the AX Digital Servo Drives series. It converts three-phase mains power into a regulated DC link and modulated motor output so automation controllers can command precise velocity and torque profiles. By integrating drive regulation, brake management, and I/O in one housing, the unit supplies compact motion control for packaging lines, handling stations, and machine tools.

The drive delivers a continuous motor current of 3 A and can supply up to 7.5 A during short acceleration peaks, providing headroom for dynamic load changes. Energy is stored in an intermediate circuit that tolerates up to 875 VDC. Its smoothing bank has a total capacitance of 235 µF, which limits voltage ripple during regenerative events. The drive provides 8 digital inputs with optical isolation, allowing machine PLCs to trigger functions such as enable, reset, or fast stop without additional interface modules. The sensor supply can furnish a minimum peak current of 1 A, supporting absolute encoders or resolver reference electronics without external power rails. The unit measures 92 mm wide, 232 mm deep, and 317.2 mm high, simplifying row mounting with other AX devices in a control cabinet.

The drive dissipates 50 W as power loss during operation. Its internal brake chopper can continuously process 50 W while supporting external braking power of up to 15 kW for brief periods. For shorter deceleration sequences, the integrated resistor accepts peak power of 14 kW. When a higher-inertia load must be stopped, an external resistor with a minimum resistance of 47 ? can be connected to the terminal block. Overcurrent protection for the 24 V control rail is provided by a replaceable fuse rated at 3.4 A.
