Product Description:
The HLR01.1N-0470-N11R7-A-007-NNNN is a brake resistor produced by Bosch Rexroth Indramat and supplied in the HLR Brake Resistors series. Mounted across the DC bus of a drive controller, it dissipates kinetic energy returned by a decelerating servo or spindle, which helps keep link voltage within permitted limits and protects power semiconductors. This passive component has no moving parts and can be wired directly to brake-chopper terminals, so it is commonly used on automated conveyors, pick-and-place axes, and packaging machines that generate frequent regenerative peaks. Because it provides a dedicated path for returned energy, it helps prevent voltage rise during rapid stopping and repeated deceleration.
The resistor can absorb a braking power of 56 kW during a single overload event lasting up to 1 s. A panel width of 223 mm and a height of 300 mm let the housing fit inside a 600 mm cabinet bay while still leaving room for convection airflow. The resistance element, terminals, and insulation are matched for use with regulated drive platforms that depend on controlled DC-bus braking. Cabinet placement should leave open air paths around the enclosure so rising heat can dissipate without collecting near adjacent modules. This layout supports stable braking performance during repeated machine slowdowns.
Each braking cycle transfers up to 56 kWs of energy into the element. The duty cycle allows a maximum on-time of 120 s, after which heat must dissipate before the next heavy braking event. The installation depth of 210 mm sets the rear clearance needed behind the mounting plate, which is important when the resistor is installed near drive electronics or back-panel wiring. A mass of 4.5 kg keeps the unit relatively easy to position on a cabinet frame or door while staying substantial enough for secure mounting.
