Product Description:
The HLR01.1N-06K5-N06R1-A-007-NNNN is a brake resistor module produced by Bosch Rexroth Indramat within the HLR Brake Resistors series. In regenerative drive systems, the resistor converts surplus kinetic energy into heat so the DC bus voltage stays within safe limits during motor deceleration. It is used where returned energy from braking axes must be dissipated outside the inverter rather than fed back into the supply. This arrangement helps prevent overvoltage trips during repeated braking events on servo and spindle applications.
The unit can dissipate a continuous thermal load of 6.50 kW, which is the heat it may release during steady operation. For rapid stops, it tolerates a short-term peak load of 98.00 kW, and that peak is limited to a duty factor of 3 %, so the resistor may be energized for only a small portion of each operating cycle. Electrical stress is set by the 6.10 Ω nominal resistance value, which sets the braking current when the module is connected to the drive's DC link. The element may stay engaged for a maximum of 3.60 s per burst, after which the brake chopper must remain open until the minimum cycle time of 120 s has elapsed. During each permitted burst, it can absorb 356 kWs of energy, making it suitable for applications with brief but intense deceleration intervals.
Installation requires a conductor size of 16 mm², which provides suitable current-carrying capacity for the transient currents produced during peak events. The housing has an IP20 rating that helps prevent accidental contact with live parts while still allowing convection cooling through the enclosure design. The resistor measures 400 mm in width, 490 mm in depth, and 270 mm in height, so it can be mounted flat on a cabinet back panel without extending past many standard enclosure depths. The assembly has a mass of 13.00 kg, which should be considered when planning panel support and mounting hardware. Its physical size also leaves room for airflow around the unit, which is important when the resistor is exposed to repeated thermal cycling.
