Product Description:

The HLR01.1N-07K0-N14R0-A-007-NNNN brake resistor is produced by Bosch Rexroth Indramat within the HLR Brake Resistors series. As a braking component, it pairs with servo drives and inverters to absorb surplus kinetic energy that returns to the DC bus during motor deceleration. Converting that energy into heat helps prevent overvoltage trips and supports controlled stopping cycles in automated machinery, conveyors, and positioning axes used in industrial automation. This role is especially useful in systems that perform frequent deceleration or repeated stopping under load.

It delivers a continuous thermal capacity of 7 kW, meaning the resistor can dissipate that amount of electrical power as heat without exceeding its temperature limits throughout the rated duty cycle. The element resistance is 43 Ω, which sets the braking current for a given DC link voltage and affects the deceleration torque available to the motor. During a regenerative event, the device can absorb 672 kWs of energy in one activation period. To prevent overheating, the resistor may remain energized for up to 120 s at a time, after which a cooling interval is required. A casing width of 600 mm allows installation alongside similarly sized drive modules inside standard control cabinets.

The short-term overload rating permits a pulse length of 16 s, enabling rapid emergency stops when commanded by the axis controller. The housing measures 490 mm in depth and 270 mm in height, so cabinet layout must allow enough clearance behind and above the mounting plate for airflow and adjacent components. The unit has a mass of 22 kg, which contributes to stable mounting when the enclosure is exposed to vibration. These physical dimensions also influence how the resistor is positioned in cabinets where thermal spacing is necessary around braking components.
