Product Description:
The HLR01.1N-01K6-N18R0-A-007-NNNN brake resistor is manufactured by Bosch Rexroth Indramat as part of the HLR Brake Resistors series. It is intended for servo drives that must dissipate regenerative energy generated during rapid deceleration, downhill movements, or emergency stops. By routing excess DC bus power into its resistive element, the unit protects connected inverters from overvoltage faults and helps keep motion control operation stable in automated material-handling, packaging, and machine-tool applications.
During steady braking events, the resistor can absorb up to 1.6 kW of power without exceeding its permitted temperature rise, while short bursts allow a peak dissipation of 34 kW. The resistive path measures 18 Ω, producing a predictable current draw that supports proper drive matching, and the element can store 109 kWs of thermal energy before cooldown is required. A maximum duty period of 3.3 s at peak load limits how long the resistor can remain at its highest braking demand in a single event. Physical integration is aided by a depth of 120 mm, a width of 185 mm, and a height of 586 mm that fit common control cabinet layouts, while field wiring is secured with a terminal tightening torque of 1.8 N·m.
Thermal cycling for repetitive braking sequences is limited by a 120 s load cycle, giving the resistor time to radiate heat between active periods. The housing carries an IP20 rating, so it must be installed inside an enclosed panel while still providing touch protection for energized parts. With a mass of 5.2 kg, the module can be handled during panel installation without lifting equipment, provided a minimum bottom clearance of 200 mm is left for airflow. Control wiring is specified for AWG 14 conductors to support the required current handling, and the terminals are oriented for straightforward top entry to simplify vertical cable routing.
