AX2006 by Beckhoff

The AX2006 is a digital servo drive manufactured by Beckhoff within the AX Digital Servo Drives series. Designed to regulate brushless servo motors in industrial automation, the unit converts three-phase mains power into a controlled output that manages torque, speed, and position for machinery such as packaging stations, pick-and-place axes, and small gantries. With a compact single-axis format, it fits modern control cabinets.

During operation, the drive can supply a peak output current of 12 A RMS, allowing brief acceleration events without saturating the power stage. Its installed load rating of 4 kVA indicates the maximum apparent power that must be allocated in the cabinet's supply network. Motor windings connected to the drive must have a phase inductance between 7.5 mH and 40 mH; staying within this range keeps current ripple and switching losses under control. When a decelerating axis regenerates energy, up to 200 W can be dissipated continuously through the internal resistor. A 24 VDC auxiliary supply powers the logic section independently from the mains. Steady thermal loading is represented by 60 W of rated dissipation, whereas the 15 W quiescent figure applies when the motor is idle.

Signal handling is analog and straightforward. The command input accepts ±10 V with an impedance of 20 k?, so most controllers can drive the input without imposing an excessive load. The monitoring output provides a 10-bit value through a 2.2 k? source resistance. Encoder signals up to 250 kHz are counted without missing edges, enabling the use of high-resolution feedback devices. An external brake resistor of 33 ? can be wired for intermittent energy dissipation above the internal limit. The power stage has a form factor of 1.01 and a residual voltage drop of 5 V between the DC link and motor terminals, which supports precise loss calculations.
