Product Description:

Beckhoff manufactures the AX2523-B900 in its AX Digital Servo Drives series. This drive converts DC bus energy into controlled three-phase output and is intended to precisely regulate motor torque and velocity within industrial automation cells, packaging lines, and material-handling stations. Integrated analog and digital interfaces allow the drive to accept speed commands, report status to the PLC, and engage safety relays, giving machine builders a compact current source that can be mounted close to the motor.

The command section presents an analog input resistance of 20 kΩ, minimizing loading on upstream controllers, and its input is digitized with a 14-bit converter for fine reference resolution. Internal processing is synchronized by an 8 kHz control clock, so current vectors are refreshed every 125 µs for stable dynamic response. Continuous motor supply is rated at 3 Arms, while transient events such as acceleration are covered by a peak capability of 9 Arms. A Btb/RTO relay can switch 500 mA, and each digital output can source 10 mA for field signaling. Quiescent dissipation is 12 W, and the form factor of 1.01 indicates that the nominal current closely matches the device’s thermal rating, keeping cabinet temperatures predictable during sustained duty cycles.

The power stage supports load inductances from 75 mH down to 12 mH, allowing the same drive model to serve high-inertia axes as well as low-inductance linear motors without retuning hardware. Heat produced at rated current is 30 W, which can be removed with standard enclosure airflow. Physical dimensions are 50 mm wide, 230 mm high, and 240 mm deep, so multiple units can be ganged on a single DIN rail with minimal spacing. The housing and connectors together weigh only 1.7 kg, easing vertical panel installations and reducing load on swing-out cabinet doors.
