RD52.1-4B-075-L-FV-FW

RD52.1-4B-075-L-FV-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers. The RD52.1-4B-075-L-FV-FW AC Drive Converter by Bosch Rexroth Indramat is part of the RD 500 Drive Controllers family designed for precision motor management. It operates on a nominal connecting voltage of 3 x AC 380-480 V and delivers a continuous rated power of 75 kW with a peak output of 116 kW. Integrated radio interference suppression filters and a field-oriented vector control algorithm ensure accurate speed and torque regulation across industrial applications.

This drive converter employs forced air cooling via an internal blower to maintain optimal thermal conditions and features a built-in brake chopper with a minimum resistance of 4.4 Ω. The unit’s Class D size category enclosure houses a three-phase power connector and a line reactor to minimize harmonics and protect upstream equipment. At 52 kg, it balances robust construction with manageable weight for cabinet integration, while properly shielded motor feedback and power cables preserve signal integrity. Additionally, a conformal coating protects the power stage against dust and moisture under arduous factory environments.

Operators interact with the RD52.1-4B-075-L-FV-FW through an intuitive panel featuring a four-line graphics display and keypad, simplifying parameter setup and diagnostics. Modular design and global warranty support enhance uptime and streamline maintenance, making this drive controller a reliable choice for packaging, extrusion, and metal-forming machinery. Its compact footprint, advanced harmonic mitigation, and precise vector control deliver performance and integration benefits in demanding industrial systems.
