RD52.1-4B-037-L-NN-G1-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-037-L-NN-G1-NN-FW from the RD 500 Drive Controllers series combines a robust Nominal Connecting Voltage of 3 x AC 380-480 V with a Rated Power of 37 kW in a precision-engineered package. This Converter with a built-in brake chopper features a field-oriented 3-phase drive system with a type-1 design optimized for industrial motion control. The device is classified as A-Class industrial equipment under EN 50082-2, ensuring immunity to electromagnetic interference. Cooling is accomplished via a forced air cooling mechanism and is specifically implemented at the rear of the power section.

Engineers benefit from advanced features such as automatic motor adaptation/parameter identification and incremental encoder emulation with resolver evaluation for seamless integration with diverse servo motors. Operation is supported by the RDwin software package, allowing PC-based commissioning, tuning, and diagnostics. The converter meets environmental class 3K3 per DIN IEC 721-3-3, and retains full performance across an ambient temperature range of 0 °C to 40 °C. Its enclosure maintains a Protection Class IP20 rating in accordance with EN 60529, safeguarding internal components in standard industrial environments.

Pulse-width modulation settings extend flexibility with a 4 kHz PWM frequency delivering an output frequency range of 0 Hz to 250 Hz, while an optional 8 kHz PWM frequency elevates the maximum output frequency to 500 Hz. The compact footprint, rugged construction, and integrated brake chopper make the RD52.1-4B-037-L-NN-G1-NN-FW an ideal choice for dynamic, high-precision drive applications in automation and process industries.
