RS51.1-4G-024-V-V1-FW

The RS51.1-4G-024-V-V1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers unit embodies advanced drive converter design. It operates from a nominal 3-phase AC 380-480 V supply and delivers 24 kVA rated power for demanding applications. The drive incorporates a built-in brake chopper with integrated resistor and an external 24 V stand-by power supply to maintain control during power disturbances. Housed in a robust IP20 enclosure, it is engineered for straightforward integration into control cabinets.

Designed as a drive controller for high-speed grinding spindles, the RS51.1-4G-024-V-V1-FW supports an output frequency range of 0–2000 Hz and features a nominal current draw of 32 A, rising to a rated current of 40 A and a peak current of 50 A for 60 s. It sustains a continuous output power of 19 kVA while tolerating ambient temperatures from 0 … +40 °C under a 3K3 environmental class rating. The unit’s cooling air flow of 0.2 m³/s removes heat effectively, and its continuous braking power of 0.6 kW is matched by an 18 Ω braking resistor and a 20 Ω brake resistor for overvoltage protection. Comprehensive radio interference suppression further ensures EMC compliance in industrial environments.

Engineers benefit from its compact footprint and plug-and-play compatibility with Bosch Rexroth’s RD 500 series, simplifying installation and commissioning. The RS51.1-4G-024-V-V1-FW’s rugged design and integrated safety features deliver reliable motor control and reduced downtime in precision machining, grinding, and process automation tasks.
