Product Description:

The CSH01.2C-SE-EN1-NNN-CCD-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. This control section plugs into IndraDrive power modules to coordinate axis motion, fieldbus traffic, and local I/O inside automated machinery. By running application software, the unit handles real-time positioning tasks and diagnostic reporting required in multi-axis industrial automation cells. Because it serves as the control section rather than the power stage, it manages command processing and feedback evaluation within the drive system.

The controller operates from a system bus fed with DC 24 V, and its internal logic draws a base power of 8.5 W, while the CCD option module adds 1 W. A brief startup surge reaches an inrush current of 4 A, so the upstream supply must tolerate that demand. Motion commands are exchanged across the embedded SERCOS III Master interface, allowing deterministic synchronization between drives. The RJ-45 engineering port supports 100Base-TX Ethernet on cable runs up to 100 m for service access and parameter transfer. Secondary encoder electronics labeled EN1 are energized by a dedicated 8 V rail at 250 mA, and the resolver channel excites the transducer with 18.2 Vpp at 4 kHz to maintain closed-loop feedback accuracy. These feedback circuits allow the controller to process position information from connected encoder hardware.

The communication section handles Sercos telegrams at up to 16 MBaud, permitting high-bandwidth data exchange with servo drives and safety nodes. A maintenance port carries RS-232 traffic at 115 kBaud over shielded cable runs limited to 15 m, providing a fallback path for diagnostics and local access. This separate serial channel remains useful when network-based access is not available. For timing-critical sequence triggers, the digital input stage supports a maximum pulse width of 100 ms. That limit helps screen brief transient signals while still recognizing valid process events.
