Product Description:

The CSH01.3C-S3-ENS-EN1-CCD-NN-S-NN-FW is a modular control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside IndraDrive power units, this board executes motion logic, coordinates axis feedback, and distributes fieldbus messages required for precise industrial automation. By combining high-speed signal processing with flexible network ports, it serves as the supervisory element that links servo feedback, analog reference values, and distributed I/O to the drive’s power stage for coordinated multi-axis packaging, material-handling, and machining lines.

The controller accepts an analog input window of ±10 V, allowing the drive to read external speed or position references without additional scaling. Its single analog output can source 1 mA at a fixed 5 V, which is suitable for sensor excitation or simple monitoring loops. Digital control lines draw 3 mA per input and can switch loads up to 0.5 A on each transistor output, enabling direct actuation of contactors or indicator lamps. Network traffic reaches the board through the real-time Sercos III bus, and an integrated 100Base-TX interface carries the telegrams while preserving deterministic update times. A dedicated RS232 service port supports parameter retrieval and diagnostic access when the fieldbus is not active.

The module supplies the first encoder channel with 12 V for standard encoder evaluation and offers a second channel that can read resolver or HSF feedback. Both feedback sockets use a D-Sub 15 female connector, which helps keep cable sets consistent across axes. All auxiliary circuits are powered from a single DC 24 V rail, and the onboard relay can switch 1 A at that voltage for pneumatic valves or safety interlocks. High-speed synchronization functions rely on a probe input that reacts within 1 µs. Cyclic Sercos traffic is routed through an 8-pin RJ-45 connector, simplifying panel wiring while maintaining full electrical isolation.
