HLR01.1N-0470-N11R7-A-007-NPNN

The HLR01.1N-0470-N11R7-A-007-NPNN is a brake resistor manufactured by Bosch Rexroth Indramat in the HLR Brake Resistors series. When paired with drive controllers, it converts surplus kinetic energy into heat during motor deceleration, preventing over-voltage in the DC-bus and allowing rapid, controlled stops in automated machinery.

A continuous braking capacity of 0.47 kW lets the unit dissipate steady regeneration without overheating, while a peak rating of 56 kW accommodates short, high-energy events such as emergency stops. The internal element presents a resistance of 13.7 Ohm, which defines the current drawn from the intermediate circuit under a given voltage. During dynamic duty cycles it can absorb up to 56 kWs of energy before thermal limits are reached. The maximum permissible on-time is 1 s, so control logic must observe this interval to avoid exceeding the specified thermal capacity.

The housing weighs 4.5 kg, providing manageable mass for panel installation. A width of 223 mm, a height of 300 mm, and a depth of 210 mm determine the required enclosure space and airflow clearance. Peak power can be applied for one second, after which the resistor must cool in accordance with its thermal time constants; this short burst capability is intended for infrequent stop commands rather than continuous duty. The specified resistance value is maintained at continuous power, ensuring predictable current even as temperature stabilizes. Combined, these mechanical and temporal limits guide engineers when matching the resistor to drive modules and setting deceleration profiles in conveyors, gantries, and other motion axes.
