Product Description:

The CSH01.1C-PB-ENS-ENS-MA1-NN-S-NN-FW motion controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It functions as the main control section in drive systems, coordinating servo drives and feedback devices to execute programmed motion sequences in automated machinery. By integrating fieldbus communication, local encoder evaluation, and analog expansion modules, the unit provides a compact platform for axis regulation and process signal conditioning in packaging lines, handling stations, and general factory automation cells. Its role is to process command data, evaluate feedback signals, and pass coordinated control values to the connected drive system.

This version supports a single-axis configuration, so the controller allocates its processing resources to one drive channel for precise velocity and position loops. Field communication is carried by a PROFIBUS interface that operates up to 12 MBaud, enabling real-time exchange of setpoints and diagnostics with a supervisory PLC. Two standard encoder evaluation ports are provided, and a standard control panel on the front face gives local parameter access. The logic section is energized by an auxiliary bus at 11.6 VDC, and under typical conditions the device draws 23.5 W. These values are useful when planning cabinet power distribution and heat dissipation.

Analog processing is handled by the MA1 expansion, which offers two differential inputs, two single-ended outputs, and an internal resolution of 12-bit. Each analog channel spans ±10 V, making the board suitable for proportional valve references or process signal acquisition. The ENS rail can furnish up to 500 mA for sensor excitation, and the analog I/O extension helps reduce the need for external terminal blocks. This configuration has no integrated safety technology, so separate safety hardware is required when STO or SS1 is needed. The combination of analog I/O and encoder support allows the controller to handle motion feedback and process-level signals within the same control platform.
