Le HCS02.1E-W0054-A-03-NNNN belongs to Bosch Rexroth’s IndraDrive C HCS02.1E series, functioning as the power section of a modular single-axis servo drive system. It handles the power conversion and amplification while working with compatible CSH01.x control section cards (like CSH01.1C-NN-EN2 or similar) to form a complete drive controller. Rated for approximately 11 kW continuous power avec 54 A peak current et 20 A rated input current, it’s designed for dynamic servo motor control in machine tools, robotique, and industrial automation.
This power section accepts 3 x 200…500 V AC ±10% mains input (50/60 Hz) and supports DC bus operation for multi-axis configurations or energy sharing. Les principales fonctionnalités incluent internal air cooling via integrated blower fan, overload capacity up to 4x rated current for short peaks, and comprehensive protection against overcurrent, surtension, sous-tension, short circuits (42 kA SCCR), and thermal faults. It operates reliably from 0 to 40°C ambient (derate above) avec IP20 enclosure rating for panel mounting, and weighs about 6.7 kilos with dimensions suitable for standard 19″ racks.
Le “W0054” code indicates 54 A rated current, “UN-03” specifies the design variant, et “NNNN” denotes standard firmware/options (no special interfaces). It’s compatible with various encoder types (EnDat, HIPERFACE, résolveur) and safety functions when paired with the right control card. Common pairings include CSH01.1C series cards for EtherNet-based communication. Units are typically available refurbished/tested with warranty for maintenance of Rexroth/Siemens motion systems.
