The Bosch Rexroth CSH01.1C-SE-ENS-NNN-S2-S-NN-FW (Part Number: R911326830) is a high-performance advanced axis control unit engineered for the IndraDrive modular drive system. It provides high-speed, synchronized communication across automated machinery via its integrated SERCOS II optical fiber interface (X20 TX and X21 RX). Equipped with the standard ENS encoder interface, it reliably evaluates signals from Rexroth IndraDyn motors, Hiperface, 1Vpp, and EnDat feedback devices.

This control section features integrated “Safety on Board” (S2 option), providing functional safety capabilities directly within the drive. The unit comes equipped with an integrated standard operating panel featuring an illuminated diagnostic display and a 4-button keypad (Esc, Up, Down, Enter) for fast local commissioning and troubleshooting. Multiple robust I/O and communication interfaces, including pluggable terminal strips (X31, X32), D-sub connectors (X4, X41), round connector (X2), and a dedicated memory card slot (X7), ensure seamless integration into demanding industrial automation environments.
