Product Description:
The RZW03.1-005-060 braking resistor is produced by Bosch Rexroth Indramat and belongs to the RZW Braking Resistors series used with Rexroth inverter drives to absorb regenerative energy during motor braking. By converting surplus DC-bus energy into heat, it prevents overvoltage faults and allows controlled deceleration or reversal of servo axes. The module follows design code 1, uses resistor type F1, and integrates into the drive cabinet as a dedicated energy-dissipation component.
The resistor body has a nominal resistance of 42 Ω, selected to match typical DC-link voltages while limiting current to safe levels. Its thermal load capacity reaches 5.5 kW, but operation must stay within a 60% duty cycle (SD) to avoid overheating. Heat flow is modeled with a time constant of 100 s, and short bursts can reach a peak-to-continuous power ratio of 1.5. The enclosure has an IP23 protection rating, making it suitable for indoor mounting and protecting it against water sprayed at angles of up to 60 degrees from vertical. The steel enclosure measures 395 mm wide, 520 mm high, and 490 mm deep, providing ample radiator surface. Drive arrangements that need lower composite resistance may use parallel units until the network reaches 30 Ω. Power conductors up to 2.5 mm² enter through the top gland, and the installation uses a single M10 thread for secure fastening.
Duty timing is constrained by a maximum energized period of 72 s, followed by a required off period of 48 s for cooling. The resistor has a mass of 26 kg, which provides thermal inertia that moderates temperature rise during the permitted operating interval. The required cooling period limits accumulated heat across repeated braking cycles. The rectangular footprint and cabinet mounting pattern allow straightforward alignment with drive controllers inside electrical enclosures.
