Product Description:

The CSH01.1C-NN-ENS-EN2-MEM-L2-S-NN-FW is a motion-control processor card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the central command module inside Rexroth drive units, processing axis commands, encoder feedback, and I/O signals so that servo drives follow programmed motion profiles. By combining encoder evaluation, analog outputs, and integrated safety on one board, the controller reduces cabinet wiring and supports the deterministic position loops used in packaging, printing, and material-handling systems.

Two analog output stages each deliver a granularity of 19.5 mV/Inc, allowing finely scaled torque or speed references to external amplifiers. The pair of ports is arranged as 2 channels, so simultaneous command of dual axes is possible without extra hardware. For discrete control, every digital driver can source up to 500 mA per output, which is enough to actuate relays or optocouplers directly. The board can reproduce position data in both absolute and incremental formats, letting legacy counters and modern PLCs read motion states from the same connector. Incoming primary feedback electronics are powered from a stabilized 12 V rail and processed by the standard encoder evaluation interface. In addition, two probe inputs capture fast edge events for register marks or tool-length measurement.

The secondary encoder channel supports 5 V sensors and sense lines up to 75 m, which helps maintain signal fidelity on long moving cables. When the MEM output is selected, position pulses are streamed at up to 1 MHz with encoder emulation, and the corresponding bus wiring may be routed up to 40 m without reflection issues. All safety conductors terminate on a 9-pin female D-Sub connector, where the integrated Safe Torque Off circuit disables power devices during a stop demand. Serial diagnostics are accessed through an RS-232 port, and no additional control communication module is installed, leaving the expansion slot free for future options.
