Product Description:

The CSH01.1C-S3-ENS-EN1-NNN-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Within a modular IndraDrive stack, this unit forms the logic layer that interprets feedback, processes motion commands, and forwards setpoints to the attached power module. It is used in industrial automation where coordinated multi-axis positioning is required and where deterministic network traffic links drives, PLCs, and safety devices during real-time production cycles. Because the control section is separated from the power stage, the same control architecture can be paired with a compatible drive module while keeping feedback handling and command processing in one place.

This version communicates over the Sercos III real-time Ethernet fieldbus and uses a shielded RJ-45, 8-pin receptacle wired to the 100Base-TX physical layer. A maximum cable reach of 100 m allows the controller to be mounted farther from related equipment while maintaining stable data exchange. During power-up, the logic experiences an inrush of 4 A, after which it draws only 7.5 W from the base section. Two programmable outputs are rated at 24 V / 0.5 A, allowing direct actuation of small relays or indicator devices. The printed circuit assembly occupies a depth of 103 mm, so it fits within the standard IndraDrive book-size housing without exceeding cabinet rail clearance. This arrangement supports compact cabinet layouts and keeps control wiring close to the associated drive electronics.

Axis feedback is handled by the EN1 evaluation channel, which provides an 8 V Hall sensor supply and an 18.2 Vpp resolver excitation while returning position data to the controller. The ENS encoder interface supplies 11.6 V at up to 500 mA, which supports multiturn encoders that need a higher supply capability. Motion-related diagnostics can generate a pulse stream whose width is limited to 100 ms for clear edge detection by external safety relays. The housing is 49.5 mm wide and 241 mm high, which preserves airflow between adjacent modules in a tightly packed drive lineup. When a stop command is triggered, the controller enforces Stop Category 0, removing torque without delay and meeting start lockout requirements for plant safety.
