Product Description:

The CSH01.1C-SE-ENS-NNN-NNN-L2-S-NN-FW is a compact control unit produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for mounting on IndraDrive power sections, it provides motion control intelligence, fieldbus interfacing, and safety monitoring for multi-axis machinery. The module oversees command sequencing, real-time feedback processing, and drive parameter storage, allowing coordinated positioning and velocity regulation in packaging lines, printing presses, and material-handling equipment without occupying separate rack space. It serves as the logical core of the drive stack, linking peripheral sensors and actuators to higher-level automation.

Communication with the machine controller is handled over the SERCOS II fiber-optic ring, and the card supports a bus speed up to 16 MBaud, permitting sub-millisecond telegram exchange for tightly synchronized axes. Internal electronics are powered through a dedicated 24 VDC supply rail and draw only 7.5 W, so heat rise inside the cabinet remains low. External devices such as light curtains or limit switches can be fed from the onboard digital I/O header; the source can deliver up to 1.1 A, sustaining numerous sensors while keeping wiring simple. Parameter data and diagnostics can also be accessed through the integrated RS232 service port that terminates on a Mini-DIN connector.

For actuator control, the module supplies high-side switching outputs that handle up to 500 mA per channel. The permissible field voltage extends up to 30 V, accommodating mixed-voltage sensor islands. Encoder feedback channels accept differential sine-cosine and TTL signals, and the supported formats are 1 Vpp, 5 V TTL, ensuring compatibility with both high-resolution analog encoders and incremental encoders used on standard servomotors. The card also includes a Safe Torque Off function, while its fixed 100 ms inrush limit and matching pulse-width limit help protect downstream relays.
