Product Description:
The HLR01.1N-0300-N17R5-A-007-NPNN is a brake resistor manufactured by Bosch Rexroth Indramat for the HLR Brake Resistors series. In regenerative drive systems, this component converts surplus kinetic energy into heat, allowing servo amplifiers and inverters to decelerate motors without overvoltage faults. By shunting excess current through a resistive element, the module maintains bus stability and protects connected drives from energy peaks generated during rapid stops or load reversals. This role is especially important on axes that brake hard or change direction quickly, where returned energy can rise sharply for a short period.
The unit is engineered for a continuous thermal load of 0.3 kW, meaning it can dissipate that amount of braking power indefinitely without exceeding its temperature limit. Short braking cycles that demand higher absorption are covered by a peak braking capability of 37 kW, and this transient rating applies only when the resistor is energized for no longer than 1 s at a time. During each deceleration event, the device may accept up to 37 kWs of energy, which reflects the thermal capacity of the resistor element during brief high-load operation. An enclosure classification of IP20 indicates that fingers and similar objects are blocked from contact with live parts, but the ventilated design requires installation inside a protected cabinet with adequate airflow.
The mechanical envelope supports panel integration with an overall height of 300 mm, a width of 123 mm, and a weight of 3 kg. Two mounting studs accept hardware with a thread size of M6, allowing secure attachment to a heat-dissipating backplate while maintaining clearance for convection. Its compact size helps the resistor fit into control cabinets where available space is limited. Shorter cable routing between the resistor and the associated drive can also help keep installation layout clean and direct.
