Product Description:

The CSH01.1C-ET-EN1-EN2-MEM-NN-S-NN-FW is a motion and logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It coordinates drive amplifiers, supervises fieldbus traffic, and executes machine sequences in packaging lines, pick-and-place stations, and other automated cells. By embedding its own processor and communication hardware, the unit delivers deterministic position commands while exchanging status data with higher-level PLCs. It provides a central point for parameter setup, diagnostics, and network management without relying on additional supervisory processors.

During power-up, the controller draws an inrush of 4 A, after which its steady demand stabilizes at 7.5 W. A differential analog channel is available and supplies 5 V / 1 mA to low-burden transducers for signal feedback. Plant networking is handled through a Multi-Ethernet interface that supports SERCOS III, EtherNet/IP, and PROFINET. The port is presented on an RJ-45, 8-pin connector for standard shielded twisted-pair cabling. All control outputs can be modulated within their rated timing envelope, preserving pulse integrity for downstream drive enable lines.

The I/O header can source up to 1.1 A to external limit switches or photo-sensors, eliminating the need for separate 24 V supply blocks in small panels. Encoder channel EN2 delivers a stabilized reference of 5 V and accepts return edges with widths up to 100 ms, supporting both incremental and absolute feedback devices. Setup, fallback configuration, and low-speed diagnostics are handled through the integrated RS232 port. The memory board operates from the controller’s own bus, so no external MEM supply is required. Its circuits remain galvanically isolated from the main logic rails to help prevent ground loops and transient coupling.
