Product Description:
The AX2090-BW80-1000 is manufactured by Beckhoff and belongs to the AX Digital Servo Drives series. It serves as an external brake resistor module that converts regenerated energy into heat whenever a servo axis decelerates or reverses, preventing voltage overshoot in the shared DC bus. By absorbing excess energy, the unit helps maintain drive reliability and keeps motion sequences in automated assembly lines, conveyors, and packaging stations within the electrical limits of the servo system.
This model has a resistance of 18 Ω, so the current drawn during each braking pulse is determined by the DC-link voltage. Its thermal design supports a continuous dissipation of 1000 W at 40 °C, which is the baseline type power reference. For short-term loading, it can reach 130 % of type power without exceeding the permissible winding temperature, and momentary peaks up to 160 % of type power are tolerated during aggressive stop profiles. When cabinet temperature rises above 40 °C, output capacity decreases by 4 % per 10 K, so warmer enclosures may require more spacing or forced ventilation. Power and sense leads terminate on IP00 screw terminals that accept 1.5 mm² conductors, equivalent to 16 AWG, to maintain a secure electrical connection between the drive and resistor bank.
The resistor is intended for operation from -30 °C up to +40 °C, with short excursions allowed to +60 °C during transport or idle storage. It withstands ambient humidity up to 85 %RH in noncondensing conditions and meets vibration class 3M2 for installation on standard machine frames. An IP20 housing protects against accidental contact while still allowing free convection for heat removal. Overall mass is 4 kg, which supports DIN rail or panel mounting near the drive and provides the thermal inertia needed for repetitive braking cycles.
