Product Description:

The CSH01.3C-ET-EN1-NNN-CCD-NN-S-NN-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It serves as the main motion and logic unit inside modular drive systems, coordinating servo axes, field devices, and higher-level PLCs through integrated network interfaces. In industrial automation cabinets, it provides centralized processing for position, velocity, and diagnostic data while minimizing wiring by hosting local and cross-communication hardware on a single plug-in module.

The communication layer is anchored by a Multi-Ethernet port set that supports the 100Base-TX physical layer in IEEE 802.3u. Cabling is connected through a shielded RJ-45 eight-pin jack, allowing direct linkage with switches and programmable controllers. The Ethernet stack coexists with the internal SERCOS III master channel, so deterministic motion commands can be routed to the X24 and X25 cross-communication sockets. For feedback, the module offers a resolver/HSF encoder interface and supplies transducers with 8 V from its dedicated regulator. Power dissipation is divided across the installed options, with the ET section drawing 2.2 W, the EN1 interface adding 6 W, and the CCD diagnostics section contributing 1 W to the thermal load.

The service interface is implemented as an RS232 channel that uses an 8-pin mini-DIN plug. It accepts shielded cables up to 15 m and supports a peak data rate of 115 kBaud for parameter access and diagnostics. When no option cards are installed, the base electronics dissipate 8.5 W, allowing passive convection inside standard control enclosures. Motion traffic between controller boards is handled by the SERCOS III Master core, which shares synchronization pulses through the X24 and X25 links to neighboring drives. These electrical and thermal values should be considered when planning mounting clearance, cabinet airflow, and power-supply capacity.
