AX52XX_LT00_4A by Beckhoff

The AX52XX_LT00_4A is a dual-channel servo drive manufactured by Beckhoff for the AX Digital Servo Drives series. The module converts power from a shared DC bus into phase-modulated outputs that energize two independent motor windings, allowing machine builders to coordinate multi-axis gantries or feeders from a single housing. Its EtherCAT system interface allows deterministic communication with motion controllers, making the unit suitable for synchronized packaging, handling, and machining tasks in automated production lines.

The control loops have an update time of 62.5 µs, so current, velocity, and position calculations remain tightly coupled to encoder feedback. General PLC variables are refreshed every 250 µs, aligning fieldbus data with the faster internal loops. The drive has 8 digital inputs that provide hardware enable, limit, and latch functions, while a single configurable digital output can forward status bits to external interlocks. The sensor port delivers 1 A at 24 V for absolute encoders, removing the need for a separate supply rail. With a DC-link ceiling of 875 VDC, the drive can share high-energy supply modules without voltage derating. Its two channels simplify cabling in articulated or parallel-axis machines.

The internal brake chopper dissipates up to 14 kW, while an external resistor path accepts regenerative peaks of 15 kW. A minimum resistance of 47 ? prevents overcurrent in that circuit. The enclosure has an IP20 protection rating, so airflow within the cabinet remains the primary cooling path. The housing measures 317.70 mm in height, 92 mm in width, and 232 mm in depth, leaving space for field-wiring channels above and below the terminal clamps. Both independent channels share the same housing, reducing the panel space needed for multi-axis configurations.
