Product Description:

The CSH01.1C-SE-EN2-EN1-NNN-S2-S-NN-FW is a configurable motion and logic controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a drive rack, this card orchestrates axis positioning, captures probe events, and forwards safety signals, enabling coordinated operation of servo inverters, I/O modules, and higher-level PLCs in automated assembly and material-handling cells. By maintaining deterministic timing between sensors and drives, it serves as the real-time core of compact multi-axis systems. It can also coordinate motion-related logic, signal handling, and axis supervision without requiring a separate standalone controller for every axis group in the machine.

In operation, the card runs from a regulated 24 VDC control supply, and its electronics dissipate only 7.5 W under base load, which helps limit cabinet heat rise. Command and diagnostic data are exchanged over the high-speed SERCOS II fiber link, allowing synchronous cycle times with compatible drive components. When analog process values are required, the output channel has a resolution of 19.5 mV/inc, supporting fine torque or pressure references without external scaling. Digital sensor lines register as ON at 15 V and OFF at 5 V, while the transistor outputs can source up to 500 mA for lamp stacks or contactors. At power-up, the board withstands an inrush of 4 A, and the secondary encoder port supplies 5.0 VDC at 350 mA for insulated feedback devices on auxiliary axes.

In position-critical applications, the first encoder interface provides an 8 VDC sensor supply, a carrier of 4 kHz for resolver excitation, and an 18.2 Vpp feedback signal that the controller converts directly to digital position counts. Edge-triggered measurements can be synchronized to a 4 µs probe pulse so that registration marks are captured with minimal latency during indexing or cutoff tasks. Field contact tasks are handled by the onboard relay rated at 30 VDC / 1 A, while safety interlocks are driven through the Safe Motion output of 24 VDC / 0.5 A. For service access, the asynchronous serial channel supports transfer speeds up to 115 kBaud, allowing data exchange and parameter transfer without disturbing the real-time network.
