Product Description:

The CSH01.1C-S3-ENS-ENS-MEM-NN-S-NN-FW controller belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It functions as a central motion and I/O processor that ties servo axes, feedback devices, and field networks together in automated machinery. By combining position loops, low-level sequencing, and network bridging inside a single rack-mount unit, it reduces cabinet space while delivering synchronized motion control to production equipment. It can also serve as the main coordination point for motion tasks that require integrated feedback handling and consistent communication between connected machine sections.

The analog front end supports a signal bandwidth of 1.4 kHz, allowing the controller to track rapid transducer changes without aliasing. Each input presents a high impedance of 160 kΩ, so connected sources are not heavily loaded during measurement. On the output side, the DAC channels supply a fixed range of 5 V at up to 1 mA, which suits reference inputs on external drives or monitoring instruments. Physical wiring enters through the S3 slot, which uses an RJ-45, 8-pin connector format, and the RS-232 service port supports cable runs up to 15 m. Relay contacts inside the unit are rated for 30 VDC at 1 A, providing a small-signal switching option for interlocks or alarms.

Real-time axis coordination is exchanged over SERCOS III, and the board accommodates 2 encoder interfaces that can process both absolute and incremental formats. The MEM channel transmits position data across distances up to 40 m and can stream differential signals at a maximum of 1 MHz, which supports high-resolution linear scales. ENS inputs provide 120 Ω termination with an 11.6 V, 500 mA sensor supply, while their low capacitance helps maintain signal integrity. This arrangement allows the controller to support direct feedback connections while preserving stable signal transfer across longer machine spans. The RS-232 connection can also be used for legacy diagnostics, and discrete status signals can be routed through onboard relays without extra interface cards.
