RD52.1-4B-090-L-NN-NN-NN-FW

RD52.1-4B-090-L-NN-NN-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers integrates robust power conversion in a modular footprint for industrial automation. This converter supports a Nominal Connecting Voltage of 3 x AC 380-480 V and delivers a Rated Power of 90 kW to synchronous or induction motors. A built-in brake chopper with integrated line reactor and radio interference suppression filter ensures compliance with EMC directives and minimizes harmonics on the supply. The unit’s compact packaging and standardized communication options simplify installation in drive cabinets and control panels.

The drive controller employs forced air cooling to sustain continuous operation under high load conditions. Dynamic performance is unmatched: it sustains 200% overload for 0.5 s and 170% overload for 1 s, while achieving a torque rise time of 0.3 ms and a current cycle time of 0.1 ms. A 32-bit floating-point signal processor executes internal control loops at high precision, supporting advanced functions such as PID, PI controller, D latch, and RS flipflop. Parameterization is accessible via the user panel, allowing adjustment of motor ramp-up/ramp-down times and adaptation curves without external tools.

Designed for seamless integration into complex motion architectures, this RD52.1-4B-090-L-NN-NN-NN-FW drive controller offers flexible technology functions—including logic gates (AND, OR, XOR), comparators, and multi-function blocks—for customized automation sequences. The modular backplane and plug-in option slots accommodate future expansions, while standardized fault diagnostics and pre-defined start-up wizards reduce commissioning time. With global support and a built-in one-year warranty, Bosch Rexroth Indramat’s RD 500 series ensures reliable, scalable performance for packaging, machine tools, and high-speed assembly lines.
