CSH01.1C-PL-ENS-NNN-MA1-L2-S-NN-FW

The CSH01.1C-PL-ENS-NNN-MA1-L2-S-NN-FW is a single-axis motion and logic controller produced by Bosch Rexroth Indramat and included in the CSH Advanced Controllers series. Designed for cabinet installation, the unit coordinates drive tasks, discrete I/O, and safety signals in industrial automation cells. Through its firmware variant it functions as the command layer between higher-level PLCs and the IndraDrive power stage, issuing position commands and processing feedback in real time.

For auxiliary electronics the controller requires a control supply of 24 VDC. Its programmable terminal block carries 16 In and 16 Out digital points, arranged as four-input, four-output groups; this segmentation supports block-wise fusing and simplifies field wiring. When the 24-volt rail is first energized, internal capacitors draw an inrush current up to 4 A, so upstream supplies must tolerate this brief surge. The designated master interface is a Parallel Interface, allowing direct hand-shaking with external motion cards or CPUs without serial protocol overhead.

The pulse generator on the logic board accepts command trains with a maximum width of 100 ms, enabling deterministic strobe or latch functions for slow-cycle processes. The 100-millisecond limit also defines the minimum interval for edge detection on the parallel port, letting the module synchronize with moderate-speed actuators or sensor strobes. During continuous operation the electronics dissipate only 7.5 W, limiting panel heat rise and permitting convection cooling in compact enclosures. A dedicated safety channel implements Safe Torque Off, which de-energizes the drive power stage without affecting feedback circuits to meet Category 0 stop requirements. These features, combined with the deterministic I/O grouping and modest power budget, give the controller the responsiveness and energy efficiency expected from Bosch Rexroth Indramat automation hardware.
