Product Description:

The CSH01.1C-S3-EN2-EN2-MD1-NN-S-NN-FW compact controller belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Within an industrial automation cell, it assumes axis-level control by calculating position loops and issuing real-time commands to the connected power module while exchanging status data with a supervisory PLC. Its purpose is to provide deterministic motion sequencing and local I/O processing, reducing machine wiring by integrating communication, processing, and encoder management inside a narrow control unit.

Master communication is handled through SERCOS III, and the controller has 2 x RJ45 ports that form a ring or line topology with neighboring devices. Each port supports the Ethernet-derived 10/100BASE-T transmission rate, so telegrams for axis position, drive diagnostics, and cyclic I/O move across a deterministic network at standard copper speeds. The MD1 option card extends local signaling with 12 optically isolated digital inputs and 8 sourcing digital outputs; the inputs accept 24 VDC logic while the outputs can switch loads up to 0.5 A. Physical dimensions of the controller are 49.5 mm in width, 241 mm in height, and 103 mm in depth, allowing high-density mounting on DIN rails without additional spacing hardware.

For position feedback, the unit offers 2 × EnDat 2.1 / 1 Vpp / 5 V-TTL encoder channels. They feed programmable evaluation logic that is clocked by a TTL capture stage rated for a maximum frequency of 1000 kHz, enabling direct connection of high-resolution measuring systems. The integrated encoder power rail supplies 5 VDC at up to 350 mA, keeping typical sine-cosine or digital sensors within their specified current budget. When cabling without sense conductors, the allowable line length reaches 50 m, while installations that use sense leads can extend to 75 m without exceeding voltage-drop limits. Uniform voltage domains across the module remove the need for external level shifters and maintain timing determinism.
