Product Description:

Bosch Rexroth Indramat manufactures the CSH01.2C-PB-ENS-MA1-CCD-NN-S-NN-FW control section as part of the CSH Advanced Controllers series. The module plugs into an IndraDrive power section and supplies motion control, fieldbus communication, and axis feedback processing for industrial automation equipment. By combining drive regulation with fieldbus and encoder interfaces, it coordinates servo axes, synchronizes machine cycles, and passes status data to a higher-level PLC. This arrangement lets one compact control section manage both motion tasks and communication duties within the same drive platform.

Its base electronic load is 8.5 W, so cabinet power calculations can assume a minor continuous draw. Field-level communication is handled through the PROFIBUS-DP port, presented on a D-Sub 9-pin female connector and supporting a bus speed of 12 MBaud for deterministic telegram exchange. Startup transients are limited by an inrush current of 4 A that lasts no longer than 100 ms, allowing standard circuit breakers to clear without nuisance trips. The engineering interface is 100Base-TX, giving direct Ethernet access for setup and diagnostics. Two external analog inputs and two analog outputs are available, each processed with 12-bit resolution, so the controller can accept reference voltages or issue scaled setpoints without an additional I/O card. A TTL capture channel accepts edge rates up to 400 kHz for high-speed position latching during fast machine events.

Axis feedback resources are expanded by the integrated SERCOS III master, which links neighboring drives for real-time cross-communication. The encoder converter digitizes incremental or absolute signals at 12 bit width and presents a fixed input resistance of 120 Ω to maintain line termination. Attached sensors receive up to 500 mA at 11.6 V from the onboard supply, so most multi-turn encoders can be powered directly. The control section can therefore handle encoder signals, latch functions, and network communication at the same time without requiring separate interface modules.
