Product Description:

The CSH01.1C-SE-ENS-NNN-MA1-S2-S-XP-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive systems, this module coordinates servo axes, processes fieldbus data, and supervises integrated safety functions. The unit includes the SE safety extension and the ENS encoder interface option, giving the system a consistent way to handle motion feedback and safety-related control tasks. By combining motion control, fast communication, and analog I/O on one compact board, it serves as a central element in industrial automation lines that require deterministic positioning and monitored operating states. Its role is to keep command processing, feedback handling, and protective functions organized within the same control platform.

Communication with drives and higher-level PLCs uses SERCOS II, carried over fiber-optic rings at 16 MBaud, keeping motion cycles tightly synchronized. For process feedback, the controller provides 2 analog input channels digitized through 12-bit converters, while setpoints are issued on 2 analog output channels. Each output step equals 5 mV per increment, allowing precise modulation of voltage-controlled devices. A D-Sub 15 female interface supplies encoders with 11.6 V at up to 500 mA, enabling direct connection of incremental or absolute feedback devices without an external supply. This arrangement supports compact cabinet layouts by reducing the need for separate signal-conditioning hardware.

The analog front end presents an input resistance of 1000 kΩ, so high-impedance sensors maintain accuracy without buffering stages. Base power consumption is limited to 7.5 W, which helps reduce heat buildup when several control sections are mounted close together. For local access, an RS232 interface supports transfer speeds up to 115 kBaud, providing a direct communication path for setup and diagnostics. Four dedicated safety inputs and a 24 V/1 A relay tie into the controller’s Safe Motion technology, allowing certified shutdown of torque or speed channels in response to external guards or light curtains. These interfaces let the controller manage both normal axis operation and monitored stop functions within the same assembly.
