Product Description:

The RZR01.1-RD52-0610-S-M-FW is a frequency converter controller produced by Bosch Rexroth Indramat within the RZR Frequency Converters series. It functions as a dedicated motor inverter, taking low-voltage DC power and generating a controlled three-phase output that drives induction or synchronous motors used in automated machinery. By integrating with higher-level PLC systems, the unit provides torque, speed, and position regulation required for conveyors, pumps, and process lines where stable motor control is needed during changing load conditions. This arrangement lets the controller adjust motor output to process demand instead of forcing the machine to operate at one fixed speed.

Its control core relies on a 24 V ±5% logic supply for the control electronics, and the power stage can deliver up to 610 A of motor current, allowing rapid acceleration on high-inertia loads. Regulation is achieved through field-oriented vector control, which resolves stator currents into torque-producing and flux-producing components for precise dynamic response. This control method helps the drive maintain smooth torque behavior during speed changes and varying load conditions. The internal design uses a single-circuit topology, so line-side and motor-side paths share one common bus and simplify cabinet wiring. The housing is rated IP20, so it must be mounted inside a closed electrical enclosure where finger contact and dust entry are limited, but water protection is not provided.

The unit operates in ambient temperatures from 0 – 40 °C; outside this range, derating or external cooling is required. During steady-state operation, the controller draws only 12 A from the auxiliary supply, which helps keep control wiring sizes modest and reduces heat inside the panel. The climatic classification 3K3 indicates suitability for industrial halls with moderate humidity and limited airborne contaminants commonly found on factory floors. It is intended for indoor industrial locations rather than wet or washdown areas. With a mass of 6.5 kg, the unit places minimal load on back-panel supports in compact multi-axis drive cabinets.
