Product Description:

The CSH02.1B-CC-EC-ET-NN-NN-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is an automation controller that issues motion commands, captures process feedback, and handles network communication for distributed drive systems. Deployed in industrial machinery, it bridges sensors, drives, and supervisory PLCs to maintain synchronized positioning and cycle timing. Its role suits machines that require coordinated axis response and stable data exchange across multiple connected devices.

This controller provides 11 digital inputs for high-speed state detection and 5 configurable digital I/O channels that can be assigned as inputs or outputs to simplify panel wiring. It accepts 3 analog inputs to read proportional process signals and generates 2 analog outputs for reference setpoints such as speed or torque commands. The embedded EC converter operates with 12-bit A/D resolution, and its response reaches a 400 kHz cutoff frequency for rapidly changing values in servo control loops. Multi-Encoder support allows the unit to read incremental, absolute, or serial feedback devices, and a 12 W power budget is available for encoder excitation. Ethernet connectivity complies with the IEEE 802.3 physical layer and supports EtherCAT, EtherNet/IP, PROFINET IO, and sercos III telegrams, with sercos III serving as the master communication bus for time-critical motion commands.

An input resistance of 120 Ω on the EC ports helps minimize signal loading during feedback acquisition. Expansion is available through 3 optional slots that accept interface or safety cards, allowing the controller to be adapted for different machine functions. The unit also includes two probe inputs for edge-precise position latches, and a secondary Multi-Ethernet interface can carry diagnostic traffic separately from the primary real-time communication channel.
