Product Description:

The HLR01.1N-0470-N11R7-A-007-NPNN is a brake resistor produced by Bosch Rexroth Indramat within the HLR Brake Resistors series. In regenerative drive systems, the resistor converts surplus kinetic energy diverted through the drive’s DC link into heat so that the connected inverter stays within its voltage limits. By providing a controlled dissipation path, it protects servo amplifiers, positioning axes, and conveyor modules from overvoltage trips during rapid deceleration or load reversal in automated production equipment. The component is intended for installation in switchgear enclosures close to the mains supply so cable impedance between the resistor and the drive remains low. Because braking energy is released as heat, the installation should allow clear airflow around the housing and adequate spacing from heat-sensitive control components.

Its electrical element presents a braking resistance of 13.7 Ω, which determines the current that flows whenever the drive shunts energy to the resistor. At rated ambient conditions, the module handles a continuous dissipation of 0.47 kW, allowing repeated low-level braking without excessive thermal buildup. For rapid emergency stops or high-inertia loads, the resistor can absorb a momentary peak of 56 kW, but this overload is limited to a maximum on-time of 1 s to keep the case temperature within safe limits. The housing depth measures 210 mm, which is useful when the unit is mounted beside power supplies inside a compact cabinet. Mounting the resistor near the drive also helps reduce the effects of long cable runs during repeated deceleration cycles.

Thermal capacity is summarized by an energy absorption rating of 56 kWs, so the resistor can absorb that amount of energy in a single braking event before cooldown intervals are required. Mechanical data show a mass of 4.5 kg, so standard panel brackets are usually sufficient to support the unit. The enclosure has a height of 300 mm and a width of 223 mm, helping cabinet layouts account for airflow space above and beside nearby drives or filter units. This form factor suits enclosed industrial installations where braking components must fit within limited panel space while remaining accessible for fixed mounting.
