Product Description:
The CSH01.2C-PB-EN2-MEM-CCD-NN-S-NN-FW is a configurable motion and I/O controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It mounts in a Rexroth drive stack and supplies axis coordination, communication routing, and encoder processing for mid- to high-end automation cells. By combining fieldbus routing with integrated encoder emulation, the unit bridges drives, PLCs, and supervisory systems, allowing deterministic command exchange and position feedback across an equipment line.
The controller offers cross-communication through a SERCOS III Master interface for real-time drive networking, while machine-level data exchange is handled on the field side through PROFIBUS. Internal electronics draw only 19.5 W from the 24 V supply, minimizing panel heat. At power-up, the module briefly pulls 4 A, and this surge is limited to a 100 ms pulse so upstream supplies may stay compact. Engineering access uses an Ethernet RJ-45, 8-pin socket that follows 100Base-TX signaling, enabling parameter downloads from standard PCs without adapters. The PROFIBUS port is a D-Sub, 9-pin female connector, simplifying daisy-chaining on legacy installations. For feedback distribution, the board can emulate absolute or incremental encoders and reproduces EnDat 2.1, 1 Vpp, or 5 V TTL signal formats, allowing replacement of multiple external splitter cards.
Signal fidelity is supported by an emulation clock of 1 MHz and a maximum cable reach of 40 m between the controller and the first downstream device. When it powers external encoders, the supply delivers 350 mA at a regulated 5 V. Runs without sense lines may extend to 50 m, while installations that use sense conductors can reach 75 m before attenuation affects edge timing. The engineering port complies with automatic crossover detection, and the encoder emulator transmits both UVW and incremental channels so retrofit drives can accept synthetic feedback directly.
