Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-S3-EN2-NNN-MEM-NN-S-NN-FW for the CSH Advanced Controllers series. The unit operates as a motion and logic processor that issues setpoints to servo drives, reads feedback from encoder interfaces, and handles peripheral signals for coordinated machine movement. When installed in a modular drive stack, it provides centralized command sequencing so that packaging, printing, or material-handling equipment can maintain precise cycle times.

The controller’s analog interface accepts a span of ±10 V, allowing linear speed or torque commands from external process controllers. An input resistance of 160 kΩ prevents source loading and minimizes signal distortion across long shielded cables. Internal electronics draw only 7.5 W in the base configuration, which aids cabinet thermal management. For real-time axis synchronization, the board links to drives through the SERCOS III ring and exchanges cyclic data with sub-100 µs jitter. Each digital output channel can supply up to 0.5 A, allowing the board to switch small relays, indicator lamps, or brake valves without an interposing module.

The optional EN2 expansion consumes 6 W and provides dual-channel encoder emulation so auxiliary devices can track the commanded position. Primary feedback is handled through the EnDat 2.1 / 1 Vpp / 5 V TTL interface, allowing connection of absolute or incremental transducers without external converters. The MEM memory cartridge requires 2 W and supports parameter backup, while its fast logic port clocks outgoing data at 1 MHz for drive-synchronous trigger signals. Two form-C relay contacts are rated for DC 1 A at 30 V, giving galvanically isolated fault or ready outputs, and network diagnostics use the S3 socket with an RJ-45 8-pin connector that plugs directly into standard Ethernet patch leads.
