Product Description:
The AX8620-0000-0000 is a single-axis servo drive from Beckhoff’s AX Digital Servo Drives series. It interfaces directly with motion controllers over the EtherCAT system bus and uses the CiA402 profile in accordance with IEC 61800-7-201 CoE standards. Within an automation cell, the unit converts DC energy into precisely metered three-phase output so that synchronous or induction motors can follow position, speed, or torque commands issued by PLCs.
The power section can charge its DC link up to 848 V DC, allowing operation on high-voltage supply modules, and it has a module sum current of 20 A for continuous line loading. Static thermal losses are limited to 8 W, and the additional power-dependent loss of 6 W/kW helps calculate cabinet cooling requirements for larger multi-axis groupings. A short-circuit withstand rating of 65 kA supports installation on feeders protected by high-capacity breakers. During standby, the logic section draws only 120 mA from the 24 V control circuit, reducing auxiliary supply loading. Motion control data are exchanged over EtherCAT in cyclic intervals specified by the CiA402 profile, and the 2.5 kg housing is light enough for DIN rail mounting without extra support hardware.
Energy produced during deceleration is redirected to a braking resistor, and the drive can process up to 75 W of continuous braking power when a resistor of at least 33 Ω is attached. A DC link capacitance of 405 µF smooths ripple currents so the bus voltage remains stable under dynamic loads. The electronics have an IP20 protection rating, making the unit suitable for clean, ventilated control cabinets. Mechanical integration is simplified by a width of 60 mm, a depth of 192 mm, and a height of 230 mm, so multiple axes can be stacked in tight electrical enclosures while maintaining the required clearance for airflow.
