Product Description:
The CSH02.1B-CC-EC-EC-NN-DA-NN-FW is a motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It serves as the coordinating head of multi-axis drive packages, receiving sensor feedback and issuing torque or velocity commands so that machining centers, material handling systems, and packaging cells execute repeatable cycles with precise timing. Designed for cabinet installation, it consolidates motion tasks that would otherwise require several separate modules. This arrangement keeps control functions centralized and allows the controller to manage synchronized axis behavior together with machine-level logic in one location.
Two differential current inputs present an input resistance of 300 Ω, which helps prevent excessive loading on upstream transmitters. Their 12-bit conversion depth yields 4096 discrete levels for accurate process variable capture, supporting stable interpretation of analog command or feedback signals. On the output side, the controller drives analog loads down to 2 kΩ, and each channel uses a step size of 24 mV per increment for predictable signal changes. Deterministic axis coupling over plant networks is supported because the unit functions as a Sercos III master. The DA hardware includes two analog inputs, two analog outputs, two configurable lines, six digital inputs, and six digital outputs for mixed sensing and actuation tasks.
Each of the six transistor outputs can source up to 500 mA, allowing direct control of devices such as contactors or brake solenoids without an added amplifier stage. Feedback flexibility is expanded by 2 multi-encoder interfaces that accept EnDat, SSI, or incremental signals, while two resolver channels support additional feedback devices in the same controller. The resolver section supplies a carrier of 11 Vpp, and the specified cable length can extend to 75 m so position signals remain stable on longer machine axes. A digital and analog I/O extension bus, together with three optional slots, allows the controller to accept added communication, counting, or measurement functions as machine requirements change.
