Product Description:

The HLR01.1N-02K0-N15R0-A-007-NNNN is a braking resistor module produced by Bosch Rexroth Indramat for the HLR Brake Resistors series. Mounted across the DC bus of a drive, it converts excess kinetic energy from decelerating motors into heat, thereby limiting bus voltage and protecting the inverter's semiconductor devices. The component is used in packaging lines, material-handling systems, and servo positioning stages where frequent braking cycles would otherwise raise regenerative voltage beyond the normal operating range. It is intended for cabinet installation and requires free airflow to remove the generated heat.

The resistor can continuously absorb up to 2 kW of braking power, a level suited to medium-frame servo axes and small conveyor zones. Its nominal resistance of 40 Ω sets the current that flows during each dissipation event and must be considered when sizing the drive's chopper transistor. A single braking sequence may inject as much as 137 kWs of energy before thermal limits are reached, which is important for applications with high-inertia loads. The permitted on-time per braking pulse is capped at 3.4 s, which is the maximum period the resistor may remain energized before cooling is required. With a mass of 6.2 kg, the unit adds thermal capacity without placing excessive weight on the panel structure.

The depth measures only 120 mm, allowing placement behind swing-out panels without fouling door hardware or crowding adjacent devices. A vertical span of 749 mm supports chimney-style convection, so heat rises away from nearby electronics when the resistor is mounted in an upright position. The width of 185 mm leaves room for cable ducts or auxiliary contactors on standard 600 mm racks. This tall, narrow form helps the module fit into control cabinets where braking hardware must be installed alongside drives, protection devices, wiring channels, and ventilation clearances.
