Product Description:

The AX2003-0000-0000 is a single-axis digital servo drive developed by Beckhoff within the AX Digital Servo Drives series. In an automation cell, it links the motion controller to the servomotor and converts low-power command signals into regulated output energy for precise positioning, speed, and torque control on conveyors, pick-and-place gantries, or CNC feed axes. Its single-axis layout makes it suitable for machines that assign one amplifier to one motor and one mechanical load. Because command processing and power conversion are housed in one unit, the axis can respond quickly to changing motion references during start, stop, and contouring moves. Cabinet heat load calculations use its dissipation at rated current of 40 W.

This model accepts differential velocity or torque commands through an analog input span of ±10 V. Its internal step size is 1.25 mV, allowing fine adjustment of the command reference. The power stage delivers a continuous motor current of 3 A RMS and supports peak demands up to 6 A RMS during acceleration and short load transients. With a rated installed load of 2 kVA, the drive suits medium-power axes with phase inductances from 12 mH to 75 mH. That operating range helps the current controller work with compatible motor windings. Dynamic braking coils can be driven directly because the integrated brake output provides 2 A, and a current form factor of 1.01 indicates near-sinusoidal line draw.

During standby, the electronics draw only 15 W from the 24 V control rail, which may source up to 1 A when no holding brake is connected. This auxiliary supply supports the control electronics even when the motor power section is not actively producing motion. The internal chopper can absorb 80 W of regenerated energy, and an external resistor of 33 Ω may be added at the designated terminals when braking demand exceeds that level. This arrangement allows higher deceleration energy to be managed without changing the basic control section. The switching devices impose a residual voltage drop of 5 V across the output stage, which should be included when calculating the minimum DC-link voltage needed for full torque production.
