Product Description:

Bosch Rexroth Indramat produces the CSH01.1C-NN-ENS-MEM-MA1-NN-S-NN-FW, a plug-in motion-control module from the CSH Advanced Controllers series. Installed in an IndraDrive converter, this board conditions field signals, evaluates encoder feedback, and executes axis-level control loops for precise motor positioning and speed regulation in automated machinery and material-handling cells. Its integration in the drive cabinet shortens communication paths and reduces latency compared with PC-based controllers.

The module has two differential analog inputs that accept ±10 V process variables, and their conversion accuracy is 12-bit, which provides 4096 discrete levels for closed-loop calculations. It also provides 2 analog output channels for actuator control. Base consumption is capped at 7.5 W, so heat rise inside the converter remains limited during continuous duty. Startup draws an inrush current of 4 A, which affects fuse sizing and cabinet wiring cross-section. A standard single-line control panel allows local parameter entry, but the communication slot is not equipped, so network links must be provided by the surrounding drive. The board evaluates incremental encoders and absolute SSI encoders through its standard encoder interface. It does not include dedicated safety technology, so risk-related functions must be handled by external safety circuits.

High-speed test pulses or simulated encoder tracks are delivered at up to 1 MHz, enabling accurate hardware-in-the-loop testing of downstream CNC or PLC counters. The encoder port supplies 500 mA at 12 V, so many external measuring systems can be powered directly from the board. For timing-critical coordination, each emulated marker can extend to 100 ms, which supports interfaces that expect longer gate times. This behavior helps the module work with counters and measuring devices that rely on extended marker windows during synchronization.
