Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-ET-ENS-MA1-MD1-L2-S-NN-FW as part of the CSH Advanced Controllers series. Installed on an IndraDrive power section, this controller handles motion sequences, local logic, and network exchange so a machine’s axes remain synchronized with a supervisory PLC. It combines drive-level processing with axis feedback handling, giving machine builders a compact way to coordinate servomotors, sensors, and higher-level fieldbuses inside automated cells. This arrangement lets the control section and power section work as a single axis-control platform.

The base board accepts commands over a Multi-Ethernet interface, allowing EtherNet/IP, PROFINET, or EtherCAT to be selected without additional hardware. A single-line display provides status text and fault information during operation. The encoder port sources 12 V so absolute or incremental encoders can be powered directly from the card. For process data, an integrated analog input is rated at ±10 V, while the onboard analog output spans 0 to 5 V; both paths share a 12-bit conversion depth to keep low-level feedback consistent with digital setpoints. The analog channels support reference signals and monitored values without a separate signal-conditioning module. The optional MA1 module adds two differential analog inputs and two analog outputs with the same voltage range, which allows closed-loop pressure or tension control to run inside the drive rather than in an external PLC.

The MD1 extension supplies 12 digital inputs at 24 V for limit switches or probes and 8 digital outputs at 24 V that can energize contactors or stack lights. A relay channel is provided for loads up to 24 V DC at 1 A, which is useful for hardware-enable chains and other discrete control tasks. Safety wiring terminates on a D-Sub 9-pin female connector, and the integrated safety function is Safe Torque Off, which removes drive power without altering sequence memory. The digital and safety connections allow local interlocks and simple machine signaling to be handled directly at the controller.
