Product Description:

The AX2020-0000-0001 is a digital servo drive produced by Beckhoff within the AX Digital Servo Drives series. This device supplies regulated three-phase power to matched motors and processes feedback in real time so motion axes can be positioned, accelerated, and braked precisely in automated machinery. By integrating power electronics, signal conditioning, and safety monitoring in one housing, it serves as the central actuator interface between the machine controller and electromechanical loads on the factory floor.

The drive incorporates two differential analog inputs. Channel 1 has 14-bit resolution, while channel 2 has 12-bit resolution, enabling fine velocity or torque commands. Both inputs accept a bipolar range of ±10 V, are buffered by a 20 kΩ input resistance, and are refreshed every 62.5 µs, which supports responsive closed-loop control at high servo update rates. On the power side, a continuous phase current of 20 A rms allows the amplifier to run motors at their rated load without thermal derating, and a peak capability of 40 A rms delivers short bursts of acceleration torque during rapid indexing. These current ratings are achieved with a residual voltage drop of only 5 V across the drive stage, which helps minimize power losses during steady-state operation.

The output current form factor of 1.01 indicates that the RMS current closely matches the average value, reducing thermal stress on motor windings. Regenerated energy can be dissipated internally up to 200 W or routed through an external brake resistor of 33 Ω for higher duty cycles. The power stage tolerates motor inductances up to 12 mH, with a lower limit of 2 mH to maintain current-loop stability. During idle states, the unit draws just 15 W, supporting energy-efficient standby operation, and the installed load rating of 14 kVA supports cabinet power planning for multi-axis systems.
