Product Description:

The CSH01.1C-S3-EN2-NNN-NNN-S1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for integration in the CSH Advanced Controllers series. It operates as the central processor of an IndraDrive stack, executing axis interpolation, safety logic, and fieldbus management for industrial automation lines that demand deterministic positioning and coordinated multi-axis motion. A separate RS-232 header is available for service-level parameter access.

An analog output rated at 5 V / 1 mA is provided for speed reference or diagnostics, and its electrical limits protect downstream instrumentation from overcurrent. General communication is handled through a RJ-45 8-Pin jack that simplifies panel wiring. Time-critical drive commands are exchanged across the optical ring of SERCOS III, giving the controller cycle-synchronous control of connected inverters. For machine guarding, a door interlock can be energized by the integrated relay that switches up to 24 V / 1 A. Feedback from linear or rotary encoders enters through a D-Sub 15 Female connector. The encoder interface supports EnDat 2.1, 1 Vpp, or 5 V TTL formats and supplies 5.0 V at 350 mA with a minimum load resistance of 35 Ω.

Additional control tasks are supported by a 100Base-TX Ethernet link that permits TCP/IP diagnostics without affecting the real-time SERCOS channel. The controller has 4 mode-select inputs that let external switches choose operating states such as jog, auto, or teach. The safety block follows Safety Technology I/O architecture and uses a 24 V / 3 mA input threshold to verify sensor signals, while actuator commands are delivered at a maximum of 24 V / 0.5 A. All safety wiring terminates on a D-Sub 9 female connector, which keeps SIL-rated circuits separate from control I/O.
