The Bosch Rexroth Indramat CSH01.1C-SE-EN2-ENS-MEM-S1-S-NN-FW is a controller from the CSH Advanced Controllers series that communicates using sercos II. It supports two encoders, with Encoder 1 accepting EnDat 2.1, 1 Vpp, and 5 V TTL signals at 5 V, 350 mA, and Encoder 2 supporting HIPERFACE, EnDat 2.1, 1 Vpp, and 5 V TTL signals at 12 V, 500 mA with a TTL input frequency of 400 kHz. Safety-related inputs operate at 24 V and 3 mA, while safety output is rated for 24 V and 0.5 A.

Product Description:
The CSH01.1C-SE-EN2-ENS-MEM-S1-S-NN-FW controller is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed in an IndraDrive rack, it executes axis interpolation, feedback evaluation, and integrated safety for servo drives used in packaging, printing, and handling cells. The unit serves as the motion interface between the machine PLC and the drive in applications that demand deterministic position loops and coordinated multi-axis profiles. Its control functions support synchronized motion where accurate command processing and stable feedback handling are required at the same time.
This model exchanges cyclic setpoints with higher-level devices over SERCOS II, allowing real-time synchronization on the ring. An internal position emulator can transmit SSI or incremental signals through a maximum cable length of 40 m, and its output clock reaches 1 MHz so downstream readers receive high-resolution references. For direct sensor wiring, the first feedback channel supports sense lines up to 75 m while sourcing up to 350 mA at 5 V, and it decodes EnDat 2.1, 1 Vpp, and 5 V TTL formats without external converters. This arrangement supports closed-loop control when physical encoder feedback and emulated position output are both needed during operation.
The second feedback input provides a regulated 5 V supply or up to 500 mA at 12 V, and it accepts HIPERFACE as well as EnDat 2.1, 1 Vpp, and 5 V TTL signals. Its TTL edge counter is rated for 400 kHz, which supports high-speed pulse processing from connected feedback devices. Safety channels are galvanically isolated and draw 3 mA at 24 V on each input, while the two semiconductor outputs deliver 0.5 A at 24 V for drive enable or STO chains. This setup supports dual-encoder operation, long cable routing inside large machines, and integrated safety functions without requiring external relays.
