The R911200266 (RS51.1-4G-024-L-V1-FW) is a Bosch Rexroth drive control unit engineered for high-speed grinding spindle applications. The device supports an output frequency range of 0 Hz to 2000 Hz and a nominal voltage of 3×AC 380-480 V, facilitating a rated power of 24 kVA and a maximum output of 30 kVA for one minute. The unit incorporates a built-in brake chopper and resistor, utilizes aluminum Elko capacitors as DC link capacitors, and features forced air cooling within a 560 x 180 mm enclosure. It is designated environmental class 3K3 according to DIN IEC 721-3-3 and requires a permanent protective conductor prior to operation. Performance may be affected if the installation elevation exceeds specified limits. Attention is required due to potential hot housing surfaces and components sensitive to electrostatic discharge.
