Product Description:

The CSH01.1C-SE-EN2-EN2-MEM-S1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into an IndraDrive power module and governs one mechanical axis, supplying set-point generation, feedback processing, and safety monitoring for coordinated motion in automated machinery. The control section also manages communication between the drive hardware and connected feedback devices so motion commands can be executed with stable closed-loop response.

This unit draws only 7.5 W of basic power, minimizing heat inside the drive cabinet. Command and diagnostic data move over the SERCOS II fiber-optic bus, allowing deterministic communication with higher-level controllers. The field wiring includes 1 analog input and 2 analog outputs for speed or torque reference signals. Four multifunction terminals provide 4 combined digital I/Os, so limit switches, drive-ready signals, or user indicators can be routed directly to the card without extra interface boards. Motion processing remains limited to a single axis, but encoder handling is versatile; the board can emulate absolute or incremental formats and accept EnDat 2.1, 1 Vpp, or 5 V TTL feedback without additional converters.

For drives that lack native feedback, the controller supplies an emulation stream up to 1 MHz, supporting high-resolution step signals at full machine speed. The encoder ports deliver a regulated 5 V supply, protecting precision transducers from overvoltage while maintaining noise immunity on long cable runs. Integrated relay contacts rated at DC 24 V / 1 A can switch valves or enable chains directly from drive logic, reducing PLC output load. Two identical feedback slots are provided as Dual EN2, allowing redundant position sources or flexible encoder connections. A D-Sub 9 connector links the Safety Technology I/O network so emergency-stop circuits and guard switches can reach the drive without external relays.
