Product Description:
The CSH02.1B-CC-EC-CN-L3-EM-NN-FW is an axis controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. In a motion system, it acts as the command processor that links higher-level automation equipment with servo drives, converting network messages into the real-time position and torque commands required for multi-axis machines on the factory floor. The unit integrates fieldbus routing, encoder supply, and functional safety so that several control tasks can be consolidated inside a single compact module.
All internal electronics are powered from a DC 24 V supply, and the module’s 17 W base power rating covers logic, diagnostics, and LED indicators. Four differential analog channels accept feedback or command signals within a ±10 V window, allowing direct interfacing with standard industrial sensors. For deterministic motion timing, the controller operates as a SERCOS III master, while a secondary CANopen bus is routed through a 9-pin D-Sub connector. Separate encoder rails deliver 500 mA at 12 V and 500 mA at 5 V. The EM interface sources 40 mA in single-ended mode, and Safe Torque Off is implemented with a discrete output that can sink 350 mA. A relay contact is limited to 30 V so that auxiliary logic can be switched without routing high energy through the backplane.
On the CANopen side, the controller supports up to 127 nodes and maintains communication over segments as long as 5000 m at 10 kBaud, which is useful for distributed conveyor or packaging lines. Bus integrity at the device plug is preserved by the factory-installed 124 Ω terminator that is trimmed to 1% tolerance and dissipates only 200 mW. The relay channel can carry 1000 mA, giving the controller a direct means to actuate brakes or contactors without an external interposing relay. Encoder channels share a ceiling of 6 W, so when multiple feedback devices are attached, the application must budget current accordingly.
