Product Description:

The RZR01.2-RD52-0610-S-M-FW is a controller from Bosch Rexroth Indramat in the RZR Frequency Converters series. It serves as a motor inverter that converts DC-link energy into regulated three-phase output for industrial drives. The unit is assigned to Line 01 and Design 2 within the series, and it is identified as a frequency converter controller for motor-inverter operation. By modulating voltage and frequency in real time, it governs speed and torque on induction or synchronous axes that require vector-based current control. This type of controller is suited for applications where stable current regulation is needed during acceleration, steady-speed operation, and changing load conditions.

The controller's logic and sensor interface are powered from an auxiliary supply of 24 V ± 5%, while its power stage can deliver up to 610 A of phase current to the connected machine axis. Internal fusing limits the electronics draw to 12 A, which reduces the load placed on low-voltage supplies. Torque response is created through field-oriented vector control, which separately regulates flux-producing and torque-producing current components. Cabinet integration is supported by the unit's IP20 housing, which provides basic finger protection and requires installation inside a closed electrical enclosure with forced airflow. Separating the control supply from the power stage helps keep command processing and feedback evaluation stable during periods of high motor demand.

Continuous operation is maintained between 0 to 40 °C, and the 3K3 (DIN IEC 721-3-3) classification indicates use in areas free of condensation or conductive dust. The power section uses a single circuitry arrangement, so one inverter leg set is present in the converter. Mechanical handling is eased by a weight of 6.5 kg, which keeps the unit relatively compact for panel mounting. The stated operating range assumes indoor industrial use with appropriate cabinet protection from moisture and electrically conductive contamination.
