Product Description:

The CSH01.1C-ET-EN2-MA1-MD1-L2-S-NN-FW is a motion control master from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It coordinates servo axes through Multi-Ethernet communication and occupies a central slot in IndraDrive drive stacks, where it handles axis commands, feedback processing, and integrated safety for industrial automation cells. By combining network management with motion processing in one module, it serves as the control layer between higher-level automation commands and the connected drive power sections.

This controller samples analog feedback with a resolution of 12-bit, so it can detect small changes on the two differential input channels. Each analog input has an impedance of 1000 kΩ, which helps limit loading on external sensors, and the 2 differential ±10 V input arrangement supports noise-resistant signal handling. Command voltages are provided by 2 channels ±10 V analog outputs, allowing external drives or actuators to receive bipolar reference signals. The digital interface includes 12 inputs for 24 V field signals, and each input draws only 3 mA per channel. The eight digital outputs switch 24 V loads and include internal current limiting to help protect downstream wiring.

Field devices can be supplied from the outputs at up to 0.5 A, and digital status signals are provided on the 8 x 24 V sourcing channels. Position feedback is handled through the EnDat 2.1 / 1 Vpp / 5 V TTL encoder interface, and a dedicated 5 V sensor supply is available for connected feedback devices. Functional safety is provided by the integrated Safe Torque Off circuit, which uses a D-Sub 9-pin female safety connector, accepts a 24 V / 3 mA STO input, and returns a 24 V / 1 A acknowledgment output. Ethernet cabling connects directly to the controller and allows simultaneous SERCOS III, EtherCAT, or PROFINET traffic so higher-level systems can use the bus that matches their topology and cycle times.
