Product Description:
The AX2020-B110-0000 is a single-axis digital servo drive produced by Beckhoff within the AX Digital Servo Drives series. The unit supplies controlled three-phase power to servo motors, accepting commands from higher-level motion controllers and returning real-time status to the plant network. By precisely modulating current and voltage, the drive handles positioning, speed, and torque loops that are fundamental to automated packaging, material handling, and machine tool applications.
Signal exchange with the controller occurs over the EtherCAT interface, eliminating separate cabling for I/O and allowing cycle times in the microsecond range. Under continuous duty, the inverter delivers a continuous output of 20 Arms, while short bursts up to 40 Arms accommodate acceleration demands. An analog monitoring channel offers 1.25 mV resolution so feedback sensors can be observed without an external converter. Thermal management is sized for 200 W of dissipation at the rated current, and the internal airflow path keeps semiconductor junctions within safe limits. The current waveform remains nearly sinusoidal, as shown by an output form factor of 1.01, and only a 5 V residual voltage drop is introduced between the DC link and motor terminals. The input resistance to analog ground is 20 kΩ, providing adequate isolation for sensitive measurement equipment.
The housing has a width of 120 mm, a depth of 265 mm, and a height of 275 mm, which allows high-density mounting in control enclosures. The assembly weighs 7.5 kg, so panel reinforcements are only needed in high-vibration zones. The power stage is rated for 14 kVA of installed load and supports motor windings between 2 mH and 12 mH. An external 33 Ω regeneration resistor can be connected to absorb excess DC link energy during rapid deceleration. The output inductance boundaries work with the 1.01 form factor to keep switching losses low, while the analog ground resistance helps maintain signal fidelity across the cabinet harness.
