The Bosch Rexroth MPN R911201365 (RS51.1-4G-014-V-NN-FW) is an AC drive controller engineered for high-speed grinding spindle applications, compatible with both synchronous and induction motors. Featuring modular software and hardware, it includes integrated brake chopper and resistor elements for overvoltage protection. The module operates on a 3-phase AC supply at 380–480 V (±10%), supporting a nominal current of 19 A and can sustain a peak current of 29 A for 60 seconds, achieving up to 18 kVA peak output, with continuous braking power rated at 11.2 kW and a resistor value of 30 Ohm. The unit provides an output frequency of 0–2000 Hz, requires 0.1 m³/sq of circulating air for cooling, measures to 'K' size dimensions, weighs 33 kg, and meets IP20 enclosure and A1-level radio interference suppression. Programming is necessary prior to commissioning.
