The Beckhoff AX Digital Servo Drives series is a family of digital servo drive systems for controlling rotary and linear motors, ranging from earlier standalone servo amplifiers to later modular and multi-axis platforms.
Across the series, the drives support high-performance closed-loop operation with digital current, speed, and position control, and they are available in single-axis, dual-axis, and multi-axis configurations to match different machine architectures. The platform also supports a broad set of motor feedback and communication options, including EtherCAT-based integration on newer generations, multiple encoder interface types, DC link grouping, 24 V control supply concepts, and external brake resistor connection where required. Depending on the generation and model, the series includes compact cabinet-mounted amplifiers, modular servo drives with shared power infrastructure, and highly integrated multi-axis systems with separate power supply, axis, and capacitor modules. Overall, the AX series is designed as a scalable Beckhoff servo drive family for machine automation tasks that require precise motion control, flexible system layout, and compatibility with a wide range of motor, feedback, and safety configurations.
