Product Description:

The CSH01.1C-S3-EN2-EN2-NNN-S1-S-NN-FW is a control section from the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. Installed in modular drive systems, this controller handles axis commands and fieldbus traffic so that servo drives can follow motion profiles sent by higher-level PLCs. Its integrated safety I/O allows the same unit to supervise emergency-stop chains and safe torque-off channels, reducing external wiring in automated assembly lines and packaging machines.

For network integration, the controller communicates through SERCOS III, providing deterministic real-time data exchange over an Ethernet physical layer. The electronics draw a base power of only 7.5 W, which helps with cabinet thermal-load calculations. Two analog monitoring channels can source up to 1 mA each, and each channel has a resolution of 19.5 mV/inc, which supports fine voltage feedback from external sensors. When the unit is first energized, its capacitors charge with an inrush current of 4 A that lasts roughly 100 ms, so upstream breakers and inrush limiters must be sized to handle that brief current peak.

The secondary encoder interface (EN2) can sense position devices over cable runs of 75 m while maintaining an input impedance of 120 Ω, which helps minimize line reflections on long installations. It accepts differential square-wave tracks up to 1000 kHz, allowing high-resolution encoders to report speed without aliasing. Digital power stages or relays connected to the controller may draw up to 500 mA per output, making it suitable for actuating contactors, indicator lamps, or pneumatic valves directly. An RJ-45, 8-pin port supports 100Base-TX wiring for service access, and the built-in Safety Technology I/O keeps motion outputs in a safe state whenever system diagnostics detect a fault.
