Product Description:
The RZR01.2-RD52-0880-P-R-FW is a frequency converter controller produced by Bosch Rexroth Indramat within the RZR Frequency Converters series. It serves as a regenerative mains inverter, returning excess energy from drive systems back to the supply bus instead of dissipating it as heat. In braking or overhauling applications, this reduces the thermal burden on resistor-based dissipation systems and keeps less waste heat inside the cabinet. By integrating with multi-axis automation assemblies, the unit conditions DC-link power and coordinates braking events across connected converter sections. Because recovered energy is fed back to the upstream supply, the controller is suited to systems with frequent deceleration cycles and shared DC-bus operation.
Its control electronics are supplied from 24 V +/- 5% auxiliary power, isolating logic circuits from the mains path. The power stage can deliver up to 880 A when the converter modules are wired in parallel, an arrangement used for high-current common DC grids. Speed and torque regulation are handled by field-oriented vector control, allowing dynamic current reversal during regenerative cycles and stable response during changing load conditions. With a housing rated IP20, the device must be installed in a closed electrical cabinet. Design 2 and Line 01 indicate the layout and connector arrangement used for this controller.
The controller supports continuous operation between 0 - 40 °C, which suits indoor industrial spaces with controlled ambient conditions. It fits the 3K3 (DIN IEC 721-3-3) environmental class, indicating tolerance for moderate dust and the absence of corrosive vapors. During normal service, the control section draws 12 A from the auxiliary source, so the support supply can be sized for steady control demand rather than motor power delivery. A transport mass of 6.5 kg supports panel mounting and reduces mechanical load on cabinet structures during installation. The controller is intended for cabinet integration under these operating conditions.
