The R911201027 (RD51.2-4B-003-P-A1-FW) is an industrial drive controller from Rexroth Indramat, designed for the regulation of synchronous and induction motors in automation environments. The unit features an IP20-rated enclosure and integrates easily into existing setups. This converter supports a nominal connecting voltage of 3 x AC 380 to 480 V (±10%) with a rated power of 3.0 kW (1.5 kW) and employs U/f curve control. The controller provides a built-in brake chopper, external standby power, starting lock-out, and filter current feedback. Forced ventilation is used for thermal management, requiring 100 mm clearance for air flow. The operator panel includes a four-line display and six pressure-sensitive keys, supporting real-time configuration. The maximum leakage current is 3.5 mA, necessitating a proper grounding system. Firmware is factory assigned and must be sourced separately.
