The Bosch Rexroth CSB02.1B-ET-EC-NN-L3-NN-NN-FW (Part Number R911338666) is an IndraDrive CSB02 basic single-axis plug-in control section designed for modular drive systems including IndraDrive HMS power sections and HMD double-axis controllers. Engineered for high-precision motion control applications, this axis card combines Multi-Ethernet real-time communication capability with integrated Safety on Board functionality to ensure optimal drive performance and functional machine safety.

This control unit includes an integrated operator control panel (HMI) equipped with a digital LCD display and four navigation keys (Esc, Up, Down, Enter) for fast on-device diagnostics, status monitoring, and commissioning. System interfacing is facilitated through dual RJ45 ports (X25 P1, X24 P2) for networked communication, a 15-pin D-sub connector (X4) for encoder evaluation, dedicated status display LEDs (H1, H24), and plug-in spring-clamp terminal connections for digital I/O and safety signals.
