AX5201-0000-0200 by Beckhoff

The AX5201-0000-0200 is a dual-channel servo drive produced by Beckhoff for the AX Digital Servo Drives series. It connects to a common DC bus and converts electrical energy into controlled, pulse-width-modulated outputs for two motors. The independent channels support coordinated motion in packaging lines, pick-and-place gantries, and similar automation cells. Regenerative braking allows energy from decelerating loads to return to the DC link, where the integrated braking system can dissipate excess energy.

With a 230 VAC supply, the drive draws an apparent power of 1.2 kVA, which helps determine the required upstream transformer and circuit breaker. The internal DC link has 235 µF of capacitance for transient motor demands and regenerated energy. Continuous braking power is dissipated as heat at up to 50 W. The DC-link voltage must remain below 875 VDC to protect the power semiconductors from excessive electrical stress. Each channel can deliver a peak phase current of 5 A, while nominal operation provides 1.5 A per channel and a combined continuous output of 3 A. The smallest adjustable peak-current setting is 0.35 A, permitting precise torque limits for actuators that require controlled force. The enclosure measures 92 mm wide, 232 mm deep, and 317.70 mm high, providing a narrow profile for installation in control cabinets.

During dynamic braking, the internal resistor can absorb up to 14 kW for short periods. An external resistor bank supports braking power of up to 15 kW when larger loads produce more regenerative energy during deceleration. The external braking resistance must not fall below 47 ?, which keeps current within the switching transistors' operating limits. The drive produces a steady power loss of 55 W, so cabinet airflow must remove the resulting heat during continuous operation. Adequate spacing around the module helps prevent heat from accumulating near adjacent drives and other temperature-sensitive control components.
