Product Description:

Bosch Rexroth Indramat developed the CSH01.1C-SE-EN2-EN2-NNN-NN-S-NN-FW as part of the CSH Advanced Controllers series. This single-axis control section plugs into modular drive racks where it processes fieldbus data, command values, and encoder feedback to coordinate servo motion. Acting as the local brain of a drive, it converts network telegrams into precise current and speed loops for industrial machinery such as packaging stations, converting lines, and material-handling gantries. Its rack-mounted layout keeps the control section separate from the power stage while allowing both functions to work together within the same drive platform.

At the electrical level, the module draws a base supply of 7.5 W, keeping cabinet heat and power demand low. One analog input channel accepts ±10 V references, while two analog outputs return motion data; each output has a span of 5 V. Four bidirectional points provide combined digital I/O. Incoming discrete signals load the circuitry with 24 V / 3 mA, whereas the sourcing outputs can switch up to 24 V / 0.5 A. During power-up, the controller can momentarily demand 4 A, so the supply path must tolerate that short surge. A single normally open relay contact provides galvanic isolation for fault or ready signals, and emergency stop functions must be handled by external hardware.

The inrush event is limited to 100 ms, which helps prevent nuisance trips after startup. Real-time communication uses a minimum SERCOS cycle of 1000 µs, enabling tight position loops when the unit operates as a SERCOS II master. Two identical encoder ports accept EnDat 2.1 / 1 Vpp / 5 V TTL feedback formats and share an internal 5 V supply for the transducers. The encoder connections and local I/O allow the control section to process feedback, reference signals, and machine status signals from one location in the rack.
