Product Description:

The CSH01.1C-SE-EN1-MEM-MD2-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into a Rexroth drive stack and supplies real-time motion, logic, and communication services to the axis that shares its backplane. By handling velocity loops, position commands, and peripheral signals, the module forms the processing layer between the machine PLC and the servo inverter, making it central to packaging, handling, and general automation lines that depend on deterministic drive coordination.

The controller operates from a nominal bus of 24 V DC, and this supply powers its logic circuits, encoder sensors, and I/O conditioning. Communication with upper-level equipment is provided through SERCOS, enabling synchronized exchange of motion data every 100 µs. For direct machine signals, the board carries 16 digital inputs for limit switches and 16 digital outputs that drive contactors or indicator lamps. Overall consumption is 18.5 W, so cabinet heat rise stays low. The unit is 241 mm high and 103 mm deep, and a front RJ-45 socket provides an RS232 service port. An SSI channel supports single-turn or multi-turn encoder evaluation.

Position feedback facilities include encoder emulation that can reproduce both absolute and incremental formats for downstream devices. The built-in sensor supply delivers 8 V, eliminating the need for an external reference line to the measuring transducer. During power-up, the module draws an inrush of 4 A, after which current returns to the steady 24 V logic level. The housing spans 49.5 mm across the rack, leaving additional rail space for expansion cards. The HSF/RSF interface supports high-speed feedback clocks, and the pulse-width generator issues 100 ms watchdog strobes. Safety functions must be handled by an external circuit.
