RD52.1-4B-037-L-V1-FW

The RD52.1-4B-037-L-V1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers delivers industry-proven performance in a compact package engineered for precision motion applications. The converter accepts a Nominal Connecting Voltage of 3 x AC 380-480 V and generates a continuous Rated Power of 37 kW with a Rated Current of 68 A at full line voltage. An integrated Unit Type design includes a built-in brake chopper for dynamic load management and a 24 V standby power supply to maintain control circuits during mains interruptions. Configurable for operation with or without an encoder, the controller utilizes advanced flux vector control to drive both induction and synchronous three-phase motors.

Designed for harsh industrial environments, the drive controller employs forced air cooling to regulate internal temperatures and sustain high-duty operation. The rugged housing measures 500 x 270 x 320 mm and weighs 33 kg, allowing knife-edge cabinet integration without sacrificing service access. A built-in brake chopper absorbs regenerated energy, while an optional encoder interface supports closed-loop positioning. Operating conditions span 0 … 40 °C with up to 90 % RH, ensuring reliable performance across factory floors. Additional parameters include peak currents up to 136 A (half-second) / 116 A (one second) / 88 A (one minute) for acceleration bursts and deceleration demands.

Seamless integration with Bosch Rexroth Indramat control architectures simplifies commissioning and maintenance, leveraging standardized fieldbus and parameter-cloning routines. The RD52.1-4B-037-L-V1-FW’s robust electromechanical design and precision flux vector algorithm ensure under transient loads. Ideal for conveyor drives, machine tools, and automated assembly systems, this drive controller combines compact dimensions with high power density to optimize system footprint and uptime.
