Product Description:

The CSH02.1B-CC-EC-CN-S5-NN-NN-FW is a motion and logic controller built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The device coordinates multiple servo drives and exchanges real-time position data over its integrated Sercos III master channel. Installed inside control cabinets, it bridges Ethernet and CAN networks so that axis groups, sensors, and higher-level PLCs remain synchronized throughout an automation cell. This arrangement lets the controller coordinate commanded motion with feedback from connected axes during machine operation.

On the CANopen side, connector X61 uses a 9-pin D-Sub plug and links the controller to as many as 127 nodes of distributed I/O or drive modules. Data exchange follows EN 50325-4, which keeps PDO and SDO handling consistent across connected devices from different vendors. A built-in bus terminator rated at 124 ohms can be enabled when the unit is installed at the end of a segment, and the network is arranged in a line topology to maintain impedance continuity. These settings affect bus length, reflection control, and device addressing on the network. Synchronous Sercos traffic is available on ports X24 P2 and X25 P1 for motion-related communication with connected drives.

Setup and diagnostics use engineering port X26, which has an RJ-45 8-pin connector and supports 100Base-TX Ethernet. The link supports cable runs of up to 100 m when shielded CAT5e ITP cable is used, allowing a connected computer to remain outside the cabinet during service work. Parameter data pass through a multi-encoder interface, so the controller can evaluate several feedback formats without extra cards. Its integrated safety layer, identified as Safe Motion, allows the system to monitor velocity, position, and stop functions directly in the drive train. Using the engineering port also keeps setup traffic separate from the motion network during configuration and diagnostics.
