CSH01.3C-ET-EN2-EN2-CCD-NN-S-NN-FW

The CSH01.3C-ET-EN2-EN2-CCD-NN-S-NN-FW, manufactured by Bosch Rexroth Indramat, is part of the CSH Advanced Controllers series. This high-performance digital control unit serves as the main brain for Bosch IndraDrive systems, plugging directly into the power section to manage motion tasks. It features a MultiEthernet master communication interface and supports a primary encoder option of EnDat 2.1/1 Vpp/TTL, ensuring deterministic data exchange and precise feedback. Additionally, the module provides two analog outputs for flexible signal routing and control loop integration.

Designed for modular expandability, the CSH01.3C-ET-EN2-EN2-CCD-NN-S-NN-FW includes two dedicated encoder module slots and one cross communication module slot populated at delivery, with a vacant safety module slot for future functional safety upgrades. The control unit’s Master Communication bus operates over MultiEthernet, combining high bandwidth with real-time determinism. Primary encoder data flows via the EnDat 2.1/1 Vpp/TTL interface, leveraging a differential serial interface for noise immunity and error resistance. Firmware and configuration are tracked on dual type plates—one for the control electronics and one for firmware revision—simplifying maintenance. The architecture supports encryption on the encoder link and adopts a serial differential protocol to safeguard against data corruption.

Integration into multi-axis systems is seamless, with plug-and-play connectivity to Indramat drive families and standard bus couplers. The rigid, industrial-grade design ensures high availability in demanding automation environments, while the modular slots future-proof the platform for safety and fieldbus expansions. Engineers benefit from consistent Bosch Rexroth tooling and diagnostics, making the CSH01.3C-ET-EN2-EN2-CCD-NN-S-NN-FW a reliable cornerstone for precision motion control applications.
