Product Description:

The CSH01.1C-PB-ENS-ENS-MEM-NN-S-NN-FW is a motion control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. As a control platform, it coordinates axis drives, manages feedback devices, and exchanges real-time data with higher-level PLCs over Profibus for synchronized machine operation. By combining encoder evaluation, analog outputs, and onboard memory channels, the unit supplies command signals that close velocity and position loops in industrial automation cells such as packaging lines, pick-and-place gantries, material-handling stations, and other coordinated machine axes.

Beneath its front panel, the controller carries a pair of D-Sub 15-pin female sockets that accept incremental or absolute encoders. The interface presents an input impedance of 120 ohms, so the cable is terminated internally for clean differential signals. The connected sensor can draw up to 500 mA from the integrated supply rail, which is stabilized at 11.6 V to keep reference levels constant. Programmed position values leave the board through two analog channels that tolerate a load of 5 kOhm; each channel changes in steps of 19.5 mV/inc, which is the smallest adjustable output change. When power is first applied, the module momentarily draws 4 A, a peak the cabinet supply must accommodate to avoid undervoltage trips during startup.

The digital side supports TTL command inputs up to 400 kHz and can generate pulse trains whose individual width reaches 100 ms, making the board suitable for step-and-direction drives that need extended dwell times. A memory channel synchronized at 1 MHz sources 20 mA and can be wired up to 40 m away, allowing remote placement of distributed I/O islands across larger machines without additional repeaters. Despite this range of signal handling, the controller’s total power draw remains at 23.5 W, allowing passive cabinet cooling and minimizing heat rise around adjacent drive modules.
