Product Description:

The CSH01.1C-ET-ENS-NNN-MA1-S2-S-XP-FW controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for multi-axis drive systems, the unit performs real-time motion processing and safety monitoring inside cabinet-mounted automation cells. By coordinating servo drives, I/O, and network interfaces, it serves as the central logic element that links machine sequencing with higher-level control architectures. It also handles coordination between axis commands and cabinet-level safety functions during machine operation.

The controller’s internal power budget is structured across several functional blocks. The base electronics draw 7.5 W, which is the continuous load created by the CPU and housekeeping circuitry. The ENS safety module adds 6 W; its dedicated supply rail operates at 11.6 V and supports logic that supervises emergency-stop channels. High-speed diagnostics in this module use a maximum TTL switching frequency of 400 kHz, allowing rapid capture of encoder fault edges. Network coupling is handled by the ET interface, which consumes only 2.2 W and keeps the added thermal load low in densely populated racks. These values support cabinet cooling and 24 VDC power-supply sizing.

External connectivity focuses on communication and motion feedback. The integrated Ethernet port supports 100Base-TX and terminates on an RJ-45 8-pin connector for direct connection to PLC networks. During power-up, the supply may deliver an inrush of 4 A, so breakers and wiring must tolerate this short peak. For analog feedback, the MA1 channel offers a bandwidth of 1 kHz, an input resistance of 1000 kΩ, and can source up to 10 mA for current reference loops. The channel also generates a 100 ms pulse-width signal that simplifies discrete position latching. A D-Sub 9-pin female connector carries Safe Motion signals, allowing category-oriented shutdown without additional field relays.
