Product Description:

The AX2513-B200 digital servo drive is produced by Beckhoff as part of the AX Digital Servo Drives series. It is intended for cabinet installation where it interfaces with a higher-level motion controller and a shared DC-link supply. Inside an automated line, the drive modulates three-phase output currents so that a synchronous or induction motor follows commanded torque, speed, or position profiles. This operating role makes it suitable for coordinated axis control in pick-and-place arms, indexing tables, conveyor sections, and similar automated equipment.

Under steady load, the unit provides a continuous phase current of 3 A rms, while brief acceleration or deceleration demands can be met with a peak capability of 9 A rms. Pulse-width modulation devices switch at an 8 kHz carrier frequency, and the current control loop is refreshed every 62.5 μs, giving the controller fine temporal resolution for dynamic correction. Fast update timing helps the drive respond quickly to load changes and maintain smooth motor current during changing motion commands. If the DC-link potential rises above 750 V, an overvoltage shutdown prevents semiconductor stress. The enclosure measures 230 mm in height, 100 mm in width, and 240 mm in depth, giving the drive a straightforward footprint for panel layouts.

The analog voltage interface is digitized with 1.25 mV resolution, and setpoint inputs draw minimal current because the input resistance is 20 kΩ. The drive supports motor inductance up to 75 mH, which helps maintain stable current regulation with larger windings. Rated loss is 35 W, while idle dissipation is 12 W, so cabinet ventilation can be matched to operating conditions instead of full-load heating at all times. A current form factor of 1.01 keeps RMS heating close to average values during operation. The 3 kg mass adds only moderate panel weight while still providing a solid mechanical package for cabinet mounting.
