Product Description:
The CSH02.1B-CC-EC-CN-L3-EC-NN-FW is a motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is intended to act as the central processing module in industrial automation, supervising a single servo drive, gathering local sensor data, and issuing deterministic commands to actuators. By combining processing, I/O handling, and communication in one housing, the unit streamlines cabinet layouts and reduces the need for separate PLC and motion cards in compact machines. This arrangement is useful in machinery where control functions must fit into a limited installation space without adding separate control hardware.
This controller operates from a logic bus of 24 V DC, eliminating the need for an additional low-voltage supply rail. Real-time motion data is exchanged through a Sercos III Master interface that delivers synchronized setpoints and captures drive feedback every cycle. For process variables, there are 3 analog inputs, and control signals can be sent through 2 analog outputs; each output can support a 2 kΩ resistive load, suiting proportional valves or analog speed references. Discrete machine states are detected with 11 digital inputs, while five configurable I/O points can be programmed as sourcing or sinking outputs to drive external relays or indicators. Two multi-encoder interfaces allow simultaneous feedback from the motor and an auxiliary measuring device, providing accurate closed-loop positioning. This supports applications that compare motor movement with an external measuring wheel or another feedback source during operation.
For broader system integration, a secondary fieldbus port supports CANopen so the controller can exchange status words with decentralized I/O stations or human-machine interfaces. Motion execution centers on a single mechanical line through its 1 control axis, while auxiliary functions can still be coordinated through the encoder channels and expansion modules. Functional safety is addressed through the integrated STO capability, which removes drive power without external relays when a stop command is triggered. The hardware platform includes 3 optional slots, allowing communication cards, memory modules, or specialized signal boards to be added without replacing the base controller. This layout supports gradual system expansion when additional interface functions are needed later.
