RD52.1-4B-001-L-NN-P1-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-001-L-NN-P1-NN-FW from the RD 500 Drive Controllers series is a high-performance Converter with a built-in brake chopper designed to drive synchronous and induction motors. It operates on a nominal connecting voltage of 3 x AC 380-480 V with an input frequency of 50-60 Hz and delivers a rated power of 1 kW. The unit employs forced air cooling to maintain optimal temperature under continuous operation. A robust IP20 ingress protection rating ensures safe installation within a suitably protected switch cabinet.

Precision control is achieved through a PROFIBUS-DP interface and on-board four-line graphical display with function keys for local programming and diagnostics. The drive maintains a continuous current of 4 A while offering an output frequency range of 0-200 Hz for fine speed regulation. Operating temperatures up to +40 °C are supported without derating, with a maximum ambient tolerance of +50 °C at 20% derating. The converter can be mounted in the G1 position up to an altitude of 1000 m above sea level, guaranteeing reliable performance in diverse industrial settings.

Standard PC software RDwin enables fast commissioning and parameterization, reducing setup times on the shop floor. With its compact footprint and built-in brake chopper, the RD52.1-4B-001-L-NN-P1-NN-FW offers a versatile solution for machine tools, assembly systems, and textile machinery within demanding motion control applications. Bosch Rexroth Indramat’s engineering ensures high operational reliability and maintenance-free service when used according to prescribed conditions.
