Product Description:

The CSH01.1C-NN-ENS-NNN-NNN-L1-S-NN-FW motion controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It operates as a drive-control module for servo axes and auxiliary automation functions where speed, position, and safety logic are processed close to the power stage. The card accepts both fieldbus and point-to-point wiring, allowing it to supervise actuators and apply immediate stop commands inside industrial machinery.

During operation, the controller draws 7.5 W from the supply backplane, so thermal load inside a sealed cabinet remains low. Each analog channel provides a reference centered on 5 V and has a maximum source capability of 1 mA, while converter steps are quantized at 19.5 mV per increment to match common ±10 V drive inputs. Eight digital outputs can sink or source up to 500 mA each, enabling direct actuation of contactors without interposing relays. For heavier loads, the onboard form-C relay handles 1 A continuous at 30 V DC. Configuration is performed through the Ethernet-based 100Base-TX engineering interface, while legacy tools may connect through the RS-232 port over cables up to 15 m in length.

Feedback processing is handled by an incremental or EnDat encoder interface with a conversion width of 12 bit, providing resolution for positioning tasks. The receiver circuit presents 120 ohm termination to suppress reflections and supplies up to 500 mA to transducers from an isolated rail rated at 11.6 V. When the rack powers up, an inrush limiter confines the surge to 4 A for 100 ms, preventing nuisance trips of upstream supplies. The logic channel can also drive encoder transmitters at the same current level to maintain signal integrity over long motor cables. Functional safety is limited to the emergency-off function rated as Category 0, which removes energy without controlled deceleration.
