Product Description:

The HLR01.1N-17K0-N05R1-A-007-NNNN is a brake resistor module manufactured by Bosch Rexroth Indramat within the HLR Brake Resistors series. It connects to the DC link of Rexroth drive controllers and converts excess electrical energy into heat during rapid motor deceleration or overhauling loads. By dissipating regenerated power, the unit helps prevent DC-bus overvoltage and keeps the drive system operating within a safe range. This supports applications with repetitive stopping, reversing, or lowering motions where returned energy would otherwise trip the drive.

The resistor is rated for a continuous braking power of 17 kW, meaning it can absorb that thermal load when the connected inverter commands frequent stops. During one braking cycle, the device can take up to 1,632 kWs of energy before reaching its thermal limit. This single-cycle capacity assumes a maximum braking period of 14 s; beyond that interval, heat would exceed the resistor’s design curve. After a braking duty, the element must cool, and the documentation allows a maximum on-time of 120 s within any 5-minute window to protect the winding insulation. Its housing depth is 490 mm, so the enclosure must provide enough rear clearance for mounting and heat dissipation.

Panel space is also set by a width of 1000 mm and a height of 270 mm, dimensions that affect rail spacing and airflow paths inside the cabinet. The assembly weighs 43 kg, so the mounting surface must support the load securely and keep the unit stable during operation. Thermal expansion, electrical clearance, and conductor routing should be planned in advance because the large surface area releases heat through passive cooling rather than fans. The module is suited to conveyor, gantry, and packaging axes that rely on stable DC-link voltage during cyclic motion.
