AX5106_LT01.10 by Beckhoff

The AX5106_LT01.10 is a single-axis servo amplifier produced by Beckhoff within the AX Digital Servo Drives series. Serving as an interface between a plant's motion controller and its permanent-magnet motor, the unit converts DC-bus energy into a pulse-width-modulated output that regulates torque and velocity. In automated assembly lines, packaging equipment, and material-handling systems, this drive provides the fast current loops and position feedback processing needed for precise axis control.

At full demand, the drive can deliver a peak output current of 13 A, allowing short-term acceleration of servomotors beyond their continuous rating. The internal DC bus is rated for up to 875 VDC; this ceiling represents the maximum permissible regenerated voltage when several axes share a common supply. A link capacitance of 235 µF stores energy and smooths ripple so the control loops remain stable during load reversals. Integrated brake chopper circuitry can absorb up to 150 W continuously, and the electronics dissipate 85 W as heat during normal operation. Eight digital inputs are provided for limit switches or homing sensors, while the auxiliary sensor rail can supply 1 A to incremental or absolute encoders.

For dynamic stops, the external braking circuit can dissipate up to 15 kW through a resistor of at least 47 ?, preventing the DC link from reaching its overvoltage limit. The drive requires cabinet rail space for its 185 mm width, 232 mm depth, and 317.70 mm height. The enclosure has an IP20 protection rating, so it must be installed inside a closed control cabinet. Its short-circuit current withstand rating is 18 kA. The drive can operate at ambient temperatures up to 50 °C and relative humidity levels up to 95%; operation beyond those limits requires derating or forced ventilation. When several units are mounted side by side, clear airflow paths are required to remove the heat they release.
