Product Description:

The CSH01.1C-S3-EN1-NNN-MD1-NN-S-NN-FW is an axis and I/O control module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It acts as the central processor inside compatible IndraDrive power sections, where it coordinates drive-based motion tasks and related machine functions. By linking encoder feedback with fieldbus communication, the module supplies deterministic command sequences that keep servo axes and peripheral devices synchronized in automated assembly lines, packaging equipment, and handling systems. This arrangement allows one control platform to manage both motion behavior and supporting I/O activity without requiring a separate standalone controller for each drive section.

At startup, the module draws an inrush current of 4 A, and after initialization its logic requires only 7.5 W of continuous power. Motion communication is carried over SERCOS III through an onboard interface that adds 1 W to the electrical load while preserving real-time data exchange. The EN1 feedback channel supplies sine signals for compatible MHD and MKD motors, and its conditioning section uses 6 W while operating with a 4 kHz carrier for high-resolution interpolation. Machine status is monitored through 12 opto-isolated digital inputs, while 8 transistor outputs switch external relays or valves. Each output can generate pulses up to 100 ms wide without losing edge alignment.

For service and diagnostics, the controller includes an RS-232 port that supports data exchange up to 115 kBaud across cable runs of 15 m. Real-time production traffic continues through the ring-topology Sercos link, which is presented on an 8-pin RJ-45 connector and operates at 100Base-TX for use with standard Cat-5e wiring between drive sections. This separation allows service access without placing additional load on the motion network. Buffered encoder processing also helps the module maintain stable timing during coordinated machine operation in compact electrical enclosures.
