AX5140-0000-0200 by Beckhoff

Beckhoff's AX5140-0000-0200 is a dual-axis module from the AX Digital Servo Drives series. It rectifies three-phase supply voltage, forms an intermediate DC link, and feeds controlled currents to synchronous or induction motors so that automated cells can position tooling, conveyors, or gantries with repeatable accuracy. By combining drive electronics and diagnostic interfaces in one enclosure, the product simplifies cabinet wiring and supports efficient setup on packaging, material-handling, and machine-tool lines. Its two-axis configuration allows a single module to control two motor channels within a coordinated automation system.

At a mains voltage of 400 V, the drive can deliver an apparent power of 28 kVA, indicating the maximum volt-ampere load the DC link can sustain without exceeding thermal limits. The drive provides a nominal continuous output of 40 A, while transient events such as acceleration or shock loading can be supported up to a peak current of 80 A. Energy is stored in a DC link with 1485 µF of capacitance, and the permitted bus voltage is 875 VDC. This energy buffer helps smooth regenerated power and maintain stable motor torque. For smaller axes, the minimum channel peak current is 18 A. An internal power loss of 510 W must be removed through cabinet ventilation. The housing measures 185 mm wide, 317.70 mm high, and 232 mm deep, while the motor connector accepts a tightening torque of 1.0 Nm.

Dynamic braking is handled by an internal resistor that absorbs 150 W continuously and tolerates surges up to 26 kW during rapid deceleration. When connected to an external resistor bank, the drive can divert as much as 32 kW, provided that a minimum resistance of 22 ? is maintained. This arrangement allows high-inertia loads to stop without tripping the DC overvoltage limit. The IP20 housing protects against accidental contact with internal components but requires installation in a clean control cabinet. Adequate enclosure airflow is required to remove heat from the module during operation. Its 185 mm width must also be considered when reserving rail space for adjacent AX-series modules.
