Product Description:

The CSH01.2C-CO-ENS-MEM-CCD-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive systems, it performs motion calculation, fieldbus bridging, and integrated safety supervision for servo axes used in packaging, printing, and material-handling equipment. Acting as an intelligence layer between plant-level PLCs and power inverters, the module processes setpoint data, monitors feedback signals, and broadcasts status to neighboring drives through its built-in cross-communication channel so multi-axis machines can operate with synchronized velocity and timing.

General control traffic is carried over CANopen / DeviceNet. Deterministic peer exchange runs on the IEEE 802.3 compliant cross-communication bus, and service access uses a 100Base-TX network that reaches the front plate on an RJ-45, 8-pin socket. Feedback from incremental or absolute encoders is connected through a D-Sub 15 connector, and power-stage coordination uses a dedicated Co interface on a 5-pole terminal. Within a drive rack, the CSH unit serves as the Cross Comm Master that distributes cyclic telegrams, and its galvanically isolated parameter memory retains data without an auxiliary supply when main control power is absent.

Power for sensing and safety is supplied locally. The encoder channel delivers a stabilized 11.6 V source at up to 500 mA, supporting high-resolution transducers without external converters. Operator prompts appear on a single-line display, so basic diagnostics can be viewed directly at the unit without additional tools. Safe torque off circuitry connects through a D-Sub 9 plug; its outputs are rated at 24 V / 0.5 A, the inputs accept 24 V at 3 mA, and an internal relay can switch 24 V at 1 A for integration with machine-level emergency stop loops.
