Product Description:

The AX2090-L807-0001 is a dedicated cooling module produced by Beckhoff for the AX Digital Servo Drives series. Integrated on top of a drive stack, the unit pushes ambient air across the heat sink to remove heat and keep semiconductor temperatures within safe limits during motion tasks on automated machinery. By maintaining stable internal temperatures, the module helps the servo drive sustain rated current and switching frequency without extra cooling equipment. It is powered from the 24 V control supply present in most control cabinets, so installation does not require a separate mains circuit. Because it mounts directly on the drive stack, the airflow path stays close to the power section and does not require separate duct assemblies.

Cooling performance is delivered through a forced ventilation principle that uses an axial fan. The factory-configured air flow direction is blowing, meaning air exits toward the drive heat sink instead of being drawn inward, which simplifies cabinet airflow. The integrated electronics operate from a control supply of 24 V DC; at this voltage the fan draws 1.3 A, which corresponds to 31.2 W. This load can be included when sizing the auxiliary power rail. An IP20 housing prevents accidental contact with live parts but does not seal against dust, so the module is intended for closed electrical enclosures with clean ambient air. The five-pin plug uses pins 1=PE, 2=+24 VDC, and 4=GND.

The assembly weighs 3.40 kg, allowing direct mounting on a DIN rail or on the drive housing without special lifting equipment. It can be stored from -25 °C to +65 °C, so units may be kept in unconditioned storage areas before installation. During fastening, the brass insert accepts a nut tightened to 2.5 Nm, while the adjacent screw connection can be secured to 3 Nm. Respecting these torque limits helps avoid thread damage and keeps the mounting secure under vibration. The mounting points are intended to hold the module firmly in place during normal cabinet operation.
