The R911203041 (RS51.1-4G-031-U-NN-FW) is a Bosch Rexroth drive control device designed for integration into three-phase drive systems. It features modular hardware and software, rear-cooled power section, and is compliant with EN 50082-2 noise immunity standards. Key specifications include a nominal connecting voltage of 3 x AC 380-480 V, a rated power output of 31 kVA, and a built-in brake chopper and resistor. The device is optimized for high-speed grinding spindle applications and includes a user panel with a copy function. Operation is suitable up to 1,000 m above sea level, and only qualified personnel should handle the unit due to live terminals. The design establishes a direct connection between protective earth and reference ground, intended for environments free of dust, with considerations for heat dissipation and storage limits for AL electrolytic capacitors.
