Product Description:

The CSH01.1C-ET-ENS-NNN-MD1-NN-S-NN-FW is a motion-logic controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a modular drive rack, it coordinates servo axes, processes encoder feedback, and exchanges command data with supervisory PLCs. By combining high-speed drive regulation with application-level logic, the device supports industrial automation lines that require deterministic control over multi-axis motion and auxiliary machine functions.

The module accepts a single-ended analog feedback path through 1 analog input channel, and an input impedance of 160 kOhm minimizes load on upstream transducers. A resolution of 1.23 mV/inc allows the controller to detect small signal changes when tracking temperature, pressure, or torque sensors. For command outputs, it provides 2 analog output channels; each channel can drive actuators or speed references through external amplifiers while maintaining a minimum load of 5 kOhm for linear operation. Multi-Ethernet communication links the unit with fieldbus nodes, and the integrated Standard ENS interface processes incremental or absolute encoder data while supplying 11.6 VDC excitation at up to 500 mA. An RS-232 maintenance port supports cable runs of up to 15 m for local diagnostics.

The analog outputs use a command step size of 19.5 mV/inc for fine positioning and discrete handling tasks, while 12 digital inputs register signals from limit switches, proximity sensors, or fault relays. Machine status is indicated or latched through 8 digital outputs, each capable of sourcing up to 500 mA of digital output current to drive contactors or warning lamps. Additional Digital I/O Extension headers allow expansion beyond the base count without altering the main board. The ENS channel's 120 ohm termination, together with shielded cabling, helps maintain signal integrity across distributed encoder paths, and the controller's 5 kHz internal scan keeps the I/O domains synchronized with the drive servo loops.
