Product Description:

The CSH01.3C-S3-ENS-NNN-CCD-S2-S-NN-FW is a motion and drive controller module built by Bosch Rexroth Indramat and delivered as part of the CSH Advanced Controllers series. The unit plugs into IndraDrive power sections and executes axis control, fieldbus exchange, and integrated safety tasks in industrial automation cells. It coordinates servo drives and peripheral I/O to maintain deterministic motion sequences on packaging, printing, or material-handling equipment.

At power-up, the controller draws a base inrush current of 4 A that lasts roughly 100 ms, after which its steady power consumption levels out at 8.5 W. The CCD link for cross-controller data exchange complies with the IEEE 802.3 Ethernet standard and is routed through the onboard 100Base-TX engineering port, allowing access from standard network tools. Real-time drive commands are transmitted over SERCOS III, so cyclic setpoints and feedback remain phase-aligned across all axes. A single-line display on the front panel shows operating state, addressing, and diagnostic codes, simplifying status checks at the panel. In multi-drive topologies, this module operates as the master node and initiates cycle timing for subordinate drives.

For position feedback, the card digitizes analog sine-cosine or serial encoder signals with 12-bit resolution at frequencies up to 400 kHz. It accepts 1 Vpp, HIPERFACE, EnDat 2.1, or 5 V TTL formats and can source 500 mA from its encoder supply, eliminating the need for external power tees. Safety is handled by the Safe Motion function block, whose dedicated 24 V / 3 mA inputs supervise gate signals while redundant relay contacts rated at DC 24 V / 1 A disconnect power when a fault is detected. Because the module acts as the master in cross communication, these safety channels allow it to issue immediate stop commands while preserving deterministic network timing.
