Product Description:

The CSH01.1C-SE-ENS-NNN-NNN-S1-S-NN-FW is a motion and safety controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for drive-based automation, it functions as the command module that links a servo inverter with the higher-level PLC, provides diagnostic data, and manages axis positioning tasks on factory lines. Through its hardware mezzanine slots and integrated communication channel, it fits into modular cabinet layouts used for compact and configurable control systems.

Internally, the unit is configured for a single-axis topology, so all control resources are dedicated to one drive channel, reducing parameter complexity in pick-and-place, conveyor, or gantry segments. During idle operation, the electronics draw only 7.5 W, limiting panel heat generation, while a brief startup demand of 4 A accommodates capacitor charging. Command and feedback data reach the board over the SERCOS II fiber ring, giving deterministic cycle times that align with the controller’s 100 ms pulse-width watchdog timer. The 11-pin encoder header supplies 500 mA to position sensors and accepts TTL feedback up to 400 kHz, so high-resolution encoders can be powered and scanned without external boosters. The device is configurable, allowing each I/O point to be assigned to motion or safety functions.

For analog speed demand, the ENS channel provides 12 bit conversion accuracy, and its flat response up to 500 kHz helps preserve signal fidelity when velocity profiles change quickly. The input path has a resistance of 120 Ω, and the dedicated rail, supported by the 11.6 V encoder supply, helps keep the reference voltage stable across long cable runs. Safety technology I/O is implemented through a D-Sub 9 connector that receives signals at the 24 V / 3 mA level and sources 24 V / 0.5 A to external contactors. This arrangement allows the controller to process analog reference signals and safety inputs at the same time.
