Product Description:

The CSH01.1C-PB-ENS-NNN-MD2-S2-S-NN-FW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. It is a motion control section that supervises axis movements, evaluates encoder signals, and applies Safe Motion technology within industrial automation systems. Integrated PROFIBUS communication links the controller to higher-level PLCs and remote I/O, allowing coordinated operation of drives and actuators. This arrangement lets the control section exchange commands and status data across the machine without requiring a separate communication module.

The analog front end is designed for sensors that expect an input impedance of 160 kΩ, minimizing loading errors on voltage sources. Each analog input is digitized with a step size of 1.23 mV/inc, so small process variations are visible to the control loop. When the application requires reference signals, the analog outputs provide voltage with a granularity of 19.5 mV/inc, which supports fine actuator scaling. During idle operation, the section draws a base power of only 7.5 W, which helps limit heat buildup in multi-axis cabinets. At startup, the inrush current reaches 4 A, so supply fusing and wiring must tolerate this brief surge without nuisance trips. Standard encoder evaluation and an SSI option are onboard, eliminating the need for auxiliary interface cards.

The controller also provides 16 extension digital inputs that recognize an ON signal at 15 V, and 16 extension digital outputs capable of sourcing up to 500 mA per point for contactors or indicator stacks. This mix of digital I/O supports direct interfacing with contactors, indicator devices, and other external control elements. PROFIBUS telegrams are exchanged at a maximum bus speed of 12 MBaud, keeping cycle times short even when multiple axes share the line. For auxiliary signaling, a form-C relay is included and is rated to switch loads up to 30 V / 1 A. An RS-232 service port supports cable lengths to 15 m for setup and diagnostics, while Safe Motion logic supervises speed and position inside the controller.
