Product Description:

The CSH01.1C-ET-EN1-NNN-NNN-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the logic core inside an IndraDrive assembly, issuing motion commands, evaluating encoder feedback, and routing data to higher-level PLCs that supervise entire production lines. The module occupies a single controller slot, interfaces with drive firmware cartridges, and links application code directly to the power stage that energizes synchronous and asynchronous servomotors in automated cells.

At the analog output stage, the unit employs an 8-bit digital-to-analog converter that produces discrete steps of 19.5 mV/inc and supports loads down to 5 kΩ. This resolution is suitable for velocity references or valve control that do not demand higher precision. Controller electronics draw a steady 7.5 W, while energization triggers an inrush peak of 4 A; cabinet fusing must tolerate that brief surge. Resolver and HSF channels process position data, and the encoder port delivers DC 8 V or AC 18.2 Vpp to maintain signal quality across mixed sensor types. The analog chain covers legacy ±10 V outputs without additional conditioning.

Communication and safety functions are handled through dedicated interfaces and separate I/O connections. Motion data move over Multi-Ethernet links that conform to IEEE 802.3u and use a 100Base-TX physical layer, enabling deterministic exchange with distributed drives and PLCs. The ET and EN1 option cards add 2 W and 6 W respectively to the power budget while remaining inside the device’s thermal limits. Safety Technology I/O lines reach the logic through a D-Sub 9-pin female connector, and the controller accepts control pulses up to 100 ms for category-oriented stop functions. Encoder profiles R0, R1, S0, and M0 can be activated in software, allowing mixed feedback architectures without rewiring.
