Product Description:

The RZR01.1-RD52-0610-P-R-FW belongs to the RZR Frequency Converters series manufactured by Bosch Rexroth Indramat. Classified as a frequency converter controller, it is intended for regenerative mains inverter duties, where drive energy is returned to the utility line instead of being dissipated as heat. In drive systems with frequent deceleration, this arrangement sends recovered energy back to the supply instead of loading external braking components. When installed in an automation cell, the device forms the bridge between servo inverters and the three-phase supply, making bidirectional power flow possible during braking cycles.

Logic and sensor circuits are supplied from a dedicated 24 V ±5% input, which isolates the control electronics from the motor bus. Torque and speed are regulated by field-oriented vector control, allowing dynamic current modulation during regeneration and stable response under changing load conditions. The power section can conduct up to 610 A toward the DC link, while auxiliary supply demand remains limited to 12 A. The housing is rated IP20, so live parts are finger-safe and the converter still requires installation inside a closed electrical cabinet with forced airflow. This layout supports use in high-power cabinet systems where power conversion and control circuits must remain separated.

The converter operates in ambient temperatures from 0 – 40 °C, and its components are qualified for the 3K3 (DIN IEC 721-3-3) environmental class, which covers indoor sites with moderate condensation risk. This classification suits industrial spaces where airborne contamination and moisture remain within controlled limits. The internal phase circuitry is arranged as Parallel, helping spread load evenly across the semiconductors during power transfer. The frame weighs 6.5 kg, which supports manageable handling during panel assembly. The product is Design 1 in Line 01.
