Product Description:

The CSH01.1C-PB-ENS-NNN-MEM-S1-S-NN-FW advanced control unit is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the central motion processor inside automation cells, translating sensor information and fieldbus commands into drive instructions. By integrating fast analog conversion, digital I/O supervision, and PROFIBUS network management, the module supports precise axis positioning and coordinated multi-drive moves for packaging and assembly machines. It occupies a single slot in the IndraDrive control rack and interfaces directly with power sections through a standardized backplane. This layout keeps command processing, feedback handling, and network exchange within one control layer.

Each analog input on the controller has a bandwidth of 2 kHz, so it can track fast sensor changes during closed-loop operation. The input impedance is 180 kΩ, which keeps transducer loading low and helps preserve signal accuracy. Analog outputs change in steps of 5 mV/inc, providing fine resolution across the ±10 V range, and the electronic circuits draw 18.5 W, which helps limit heat buildup inside the cabinet. Digital inputs switch on at 15 V, improving noise immunity on long wiring runs. PROFIBUS-DP carries cyclic setpoints, while an RS-232 port remains available for local service access. During power-up, the input stage tolerates a 100 ms charging pulse.

The encoder supply delivers 500 mA at 11.6 V, enough for absolute or incremental sensors connected to the control unit. For simulation tasks, the controller can emit reference edges up to 1 MHz, allowing drives to check following-error response without external pulse hardware. The service port reaches 115 kBaud, which supports quick serial communication and trace collection. A start-up surge of 4 A lasts 100 ms and must be considered when sizing upstream protection. The internal safety relay carries 1 A continuously, allowing fast interruption of actuator enable circuits when required. The relay is intended for control-level safety switching rather than direct load power.
