Product Description:

The HLR01.1N-08K0-N06R0-A-007-NNNN brake resistor is manufactured by Bosch Rexroth Indramat as part of the HLR Brake Resistors series. This component connects across the DC link of a drive package to convert surplus kinetic energy into heat during deceleration and prevent overvoltage in industrial automation axes. When paired with the designated converter, the resistor provides a passive, maintenance-free way to handle regenerative power from servo motors and helps keep the power module within a safe operating range during frequent rapid stops.

It supplies a continuous braking capacity of 8 kW, so applications such as gantry drives or hoists can bleed off steady regenerative power without thermal overload. The element’s resistance of 7.06 Ω sets the current that flows at a given DC-link voltage, and that current determines the instantaneous power the resistor must dissipate. Bosch Rexroth specifies the unit for direct connection to the HCS03 converter family, allowing direct integration and coordinated fault monitoring. For brief emergency stops, the resistor tolerates a peak dissipation of 105 kW for up to 6.3 s, while its thermal mass can absorb 660 kWs of energy before reaching its temperature limit. These values allow the braking circuit to be selected according to duty cycle instead of only peak demand.

The enclosure stands 270 mm tall, spans 595 mm wide, and measures 490 mm deep, so adequate airflow must be provided around both faces. A mass of 16 kg adds thermal inertia that slows temperature rise between pulses, and mounting lugs are included to support that load. Cable entries align with the width, simplifying routing toward the converter and reducing loop area for emitted noise. The housing is intended for control cabinet mounting with enough clearance around the resistor surfaces for heat dissipation during repeated braking events.
