Product Description:

The CSH01.1C-S3-NNN-NNN-MD2-L2-S-NN-FW is an advanced controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It is installed in drive cabinets to coordinate servo axes and peripheral devices in automated machining, packaging, or material-handling lines. The unit transmits cyclic command and diagnostic data through the SERCOS III real-time ring, allowing tight synchronization between multiple drives and the factory network. By combining analog measurement channels with flexible digital I/O, the controller links motion commands with sensor feedback while maintaining safe torque interruption when required. This arrangement also allows the controller to coordinate axis behavior while monitoring switches, sensors, and interlocks at the machine level.

The analog front end accepts position or process signals through a differential input that presents an impedance of 160 kΩ, minimizing loading on sensitive transducers. Command values are delivered to external actuators by an 8-bit converter whose step size is 19.5 mV/inc, and loads as low as 5 kΩ can be driven without degrading linearity. Internal driver stages can source up to 0.5 A per MD2 output channel, which is suitable for pilot valves, lamps, or contactors. Ethernet-based diagnostics reach the board over a shielded, keyed RJ-45 8-pin connector that follows the IEEE 802.3 electrical standard. These electrical features allow the board to exchange process data quickly while supporting stable signal handling for connected devices.

The controller includes 16 digital inputs and a matching number of sourcing outputs for deterministic machine interfacing, and each input group is sampled simultaneously so signal skew is eliminated. Its relay contacts are rated at 1 A for switching auxiliary circuits. Option 3 equips the unit with digital I/O and an SSI encoder port that supplies 24 V to absolute feedback devices, and two fast probe inputs capture edge-triggered position marks for camming routines. Functional safety is provided by the certified Safe Torque Off channel, which cuts drive power independently of the main control operation when a stop command or fault is detected. The sourcing outputs also support direct machine interfacing for indicators and other low-power control loads.
