RD52.1-4B-015-L-NN-NN-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-015-L-NN-NN-NN-FW from the RD 500 Drive Controllers series is a high-performance field-oriented converter designed for demanding industrial applications. This unit accepts a nominal connecting voltage of 3 x AC 380-480 V and delivers a rated power of 15 kW via its three-phase supply. Equipped with a Converter with a built-in brake chopper, the RD52.1-4B-015-L-NN-NN-NN-FW ensures rapid energy dissipation under dynamic load changes. The device maintains safe operation through its start inhibitor function, compliant with EN 60 204-1 specifications, preventing unintended motor starts during setup and maintenance.

Featuring a comprehensive operator interface, this drive includes a four-line graphical display for clear status messages and diagnostic codes. Programmable ramp-function generators provide smooth acceleration profiles, while integrated comparators and timers enable precise sequence control without external PLC intervention. The drive’s forced air cooling design efficiently evacuates heat from the power section, and its IP20 protection rating safeguards internal components from dust and incidental contact. Housed in a robust size class B enclosure, the converter is optimized for cabinet installation in high-density control layouts.

Installation and maintenance are straightforward thanks to the drive’s modular architecture, which includes DC link and AL capacitors in the supply modules. The unit can be parameterized via menu prompts on the user panel, with critical operating conditions displayed until resolution. Rated for use in machine tools and general automation, the RD52.1-4B-015-L-NN-NN-NN-FW features a one-year warranty and is engineered to withstand storage temperatures from -25 °C to 70 °C. With its proven Bosch Rexroth Indramat reliability and built-in safety functions, this converter offers a reliable solution for precise motor control in industrial environments.
