Product Description:

The CSH01.2C-CO-ENS-MEM-CCD-NN-S-NN-FW is a motion control processor card from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Installed inside IndraDrive power sections, this plug-in module handles axis coordination, fieldbus communication, and local I/O preprocessing in automated machinery. By combining communication interfaces and high-speed encoder evaluation on one board, the unit serves as the central command element for servo drives, packaging stations, and material-handling equipment, translating PLC-level commands into precise current and position loops. It also helps keep control tasks inside the drive, which reduces the need for separate external interface hardware in compact automation cabinets.

Cross-communication with neighboring drives is implemented through the onboard Ethernet interface, which supports 100Base-TX signaling and uses a screened industrial connector that follows the RJ-45, 8-pin layout. When shielded twisted-pair cabling no longer than 100 m is maintained, this link sustains deterministic data exchange for synchronous multi-axis motion. Start-up transients are moderated by an inrush limit of 4 A, allowing the controller to energize without overloading cabinet power supplies. The encoder subsystem presents an input impedance of 120 ohms, matching differential line drivers and minimizing signal reflections across long feedback cables. This supports stable signal transfer where several axes must exchange timing and motion data at the same time.

The ENS analog-to-digital converter resolves feedback signals with 12-bit granularity, giving sufficient position fidelity for medium-accuracy servo loops. Its programmable anti-alias filter accepts frequencies up to 500 kHz, so high-speed incremental encoders can be read without clipping. Internal sensor excitation is sourced from the board at up to 500 mA, eliminating the need for separate supplies when powering reference transducers. For memory-based position latching, the MEM output stage can stream marker pulses at a ceiling of 1 MHz, supporting electronic gearing and registration applications on high-throughput production lines. These functions allow the card to process incoming feedback, condition signals, and pass time-sensitive position data to the drive with minimal delay.
