Product Description:
The RZW02.1-007-006 is a braking resistor module produced by Bosch Rexroth Indramat within the RZW Braking Resistors series. Installed across the DC link of Rexroth drive controllers, this component converts surplus kinetic energy into heat whenever a motor decelerates, keeping the bus voltage within safe limits for industrial automation systems. It follows the series’ line 2, design 1 classification, which defines its mechanical footprint and electrical interface with the drive cabinet.
The resistor’s continuous energy absorption capability is 7.5 kW, derived from a nominal resistance of 33 Ω. Within a load cycle of 120 s the unit should be energized for no more than 6% SD, translating to a maximum conduction window of 7.2 s followed by at least 112.8 s of cooling. This duty profile prevents thermal saturation of the aluminum element and aligns with the 300 s thermal time constant that characterizes heat dissipation to the housing. For safe wiring the module accepts a 10 mm² grounded conductor and a separate power link whose minimum external resistance must not fall below 30 Ω, protecting the drive in cascaded resistor arrays. The M6 mounting thread anchors the housing directly to the cabinet wall to maintain thermal contact.
Mechanical integration is uncomplicated: the extruded heat sink spans a width of 486 mm, stands 120 mm tall, and extends 92 mm from the mounting surface, so cabinet planners must reserve airflow clearance. The enclosure carries a IP20 protection class, indicating finger-safe openings yet requiring installation inside a shielded panel. Despite its sizeable dissipative rating the assembly weighs only 2.3 kg, minimizing load on sheet-metal brackets. The specified duty period of 120 s meshes with the 300 s thermal lag, ensuring temperature returns to baseline before the next braking event. Together these physical and temporal parameters complement the electrical limits outlined above and allow the resistor to deliver repeatable braking performance within multi-axis Indramat drive systems.
