CSH01.1C-PL-EN2-ENS-NNN-S1-S-NN-FW

The CSH01.1C-PL-EN2-ENS-NNN-S1-S-NN-FW is a motion and machine control module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Serving as the central processing section of an IndraDrive system, the unit coordinates axis commands, manages feedback from attached encoders, and distributes real-time data to higher-level automation cells. In industrial automation lines it provides deterministic sequencing so servo drives, sensors, and safety elements operate under a unified timing model.

For analog command chains the controller provides 2 voltage or current outputs, permitting actuator set-point generation without extra I/O cards. Each digital output channel can deliver 500 mA, while the total budget is 1000 mA; these limits set the load that lamps, relays, or solenoids may draw without external drivers. Encoder power rails include an EN2 line that sources 350 mA and an ENS feeder fixed at 12 V, supplying incremental and multiturn encoders with stable power during fast transients. Master communications use a Parallel Interface, so position latches and drive-ready states are exchanged in hardware-synchronized word formats. The Safety Technology I/O option segregates emergency stops and guard contacts from standard logic to ensure risk-reduction actions are executed independently of user code.

The parallel bus is complemented by 16 digital inputs and 16 digital outputs, giving the PLC layer a balanced channel count for step sequences, limit switches, and user signals without additional terminal modules. Where point-to-point diagnostics or commissioning tools are preferred, the onboard RS232 port exposes parameter access using simple ASCII telegrams, simplifying service in legacy plants. By combining these discrete channels with the current reserves, encoder feeds, and safety partitioning detailed above, the controller adapts to mixed-technology machines that require fast synchronous control on critical axes while still supporting conventional field wiring for auxiliary devices.
