Product Description:
The CSH01.1C-S3-EN1-NNN-MA1-NN-S-NN-FW is a single-axis motion and I/O controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is designed to sit in a multi-module drive rack and exchange deterministic motion commands with inverters and servo amplifiers. By combining fieldbus communication, encoder processing, and analog acquisition on one plug-in card, the unit coordinates position loops, gathers process signals, and forwards reference values to the power section of an industrial automation cell.
The control channel is established over SERCOS III, and the copper medium is accessed through an RJ-45, 8-pin port that conforms to the 100Base-TX Ethernet standard. This link forms the real-time network that schedules cyclic data and facilitates automatic device addressing. The EN1 sub-module conditions that traffic and consumes 6 W of internal power drawn from the rack backplane. Feedback from the motor is interpreted with combined resolver and HSF algorithms, and the high-speed feedback path requires only 1.0 V of differential signal amplitude, minimizing noise injection on long encoder leads. Resolver excitation is supplied at 4 kHz with 18.2 Vpp to maintain carrier integrity during rotation, while a separate S3 logic slice operates digital housekeeping on just 1 W.
The HSF interface is powered by a regulated 8 VDC source so the sensor pair can be driven without an external supply. For process data, the MA1 analog section offers 2 differential channels of input and two single-ended voltage outputs. Both directions share a programmable span of ±10 V, allowing symmetrical control signals for servo valves or transducers. Each conversion is trimmed to 12-bit resolution, providing 4096 discrete codes per range while the MA1 logic draws only 2 W under full throughput. These resources allow the controller to handle fine motion interpolation, gather load cell feedback, and issue analog commands without overloading the shared power budget of the drive cabinet.
