Product Description:

The HLR01.1N-17K0-N02R6-A-007-NNNN is a brake resistor module produced by Bosch Rexroth Indramat for the HLR Brake Resistors series. Installed on the DC link of drive controllers, the unit converts surplus kinetic energy from decelerating servo axes into heat so that overvoltage does not reach sensitive power electronics. By providing a controlled energy sink, it supports precise braking cycles in packaging machines, handling systems, and general factory automation without requiring additional active components. This function helps stabilize the DC bus during repeated deceleration events, especially in systems with rapidly changing loads.

The resistor can dissipate a continuous thermal load of 17 kW. This is the amount of heat it can release continuously without exceeding its temperature limits. For short duty peaks, it tolerates a momentary load of 144 kW, allowing rapid deceleration of heavy inertial masses. Each braking pulse may inject up to 930 kWs of energy before cooldown is required, and the permissible duration for a single peak is limited to 7.2 s. These values are used to set braking profiles, duty cycles, and repetition rates so the resistor and nearby components remain within normal operating limits.

The module has a width of 995 mm, a height of 460 mm, and a depth of 490 mm. With a transport and installed mass of 54 kg, the mounting structure must support the static load while preserving airflow around the cooling surfaces. Because the housing spans nearly one meter, the unit is often placed on the enclosure roof or on a dedicated frame to keep interior panel space available for power electronics. The thermal layout used by Bosch Rexroth Indramat assumes unobstructed convection paths, so the installation should leave open space around the housing in line with its outer dimensions.
