Product Description:

The CSH01.1C-CO-ENS-NNN-CCD-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit installs in IndraDrive drive stacks and handles axis computations, fieldbus routing, and safety monitoring inside an automation cabinet. By combining motion processing with decentralized I/O, it allows the drive system to exchange data with upstream PLCs while executing drive-internal loops for speed, torque, and functional safety. It serves as the primary intelligence layer for servo and spindle channels in packaging, handling, and machining cells.

The analog front end is designed for sensor compatibility. A high input resistance of 180 kΩ minimizes loading on voltage-mode transducers, while the designated output channel can source up to 1 mA into process actuators. That channel remains linear when the connected burden does not fall below 5 kΩ, and each incremental step is resolved at 19.5 mV/inc to match the converter bit depth. For reliable fieldbus termination, the integrated Co Bus resistor is fixed at 124 Ω, eliminating the need for external plug-on terminators in short node strings. These parameters help maintain signal fidelity and simplify wiring in closed cabinets.

Mechanical retention of the spring terminal is achieved with a prescribed tightening moment of 0.5 Nm, preventing conductor slippage during vibration. Data exchange with neighboring drives or PLC masters occurs through the dual-protocol channel supporting CANopen / DeviceNet, so the stack can use either address scheme without hardware changes. The encoder socket feeds feedback devices with a regulated 12 V supply, and the ENS interface draws only 6 W, leaving headroom for additional low-power modules on the shared 24 V rail. Safety I/O is routed through a D-Sub-9 connector and accommodates 24 V inputs at 3 mA and redundant 0.5 A outputs for emergency stop chains.
