Product Description:

The CSB01.1C-SE-ENS-NNN-L2-S-NN-FW belongs to the CSB Drive Controllers series produced by Bosch Rexroth Indramat. It supplies the closed-loop processing electronics that sit on top of a power section and directs the energy delivered to a servo motor. In automated assembly lines, packaging equipment, and material-handling gantries, the unit serves as the central motion processor, converting network commands into precisely timed current patterns that achieve accurate axis positioning and continuous torque regulation.

Internally, the controller supervises a single-axis drive, so all feedback channels and command paths are dedicated to one mechanical load. Real-time coordination with neighboring devices travels over the SERCOS II fiber-optic bus, which carries cyclic setpoints and status words at deterministic intervals. Local machine signals are handled by integrated digital inputs and outputs, removing the need for auxiliary I/O cards. Rotor position feedback terminates on the IndraDyn Motors interface, while analog encoder amplitudes down to 1 Vpp are accepted without external converters. For local diagnostics or serial scripting, a built-in RS-232 port exposes a command channel that remains active even when the fieldbus is offline.

Additional resources reside on the removable MultiMediaCard, which stores parameter sets and device history. The controller also interprets the bidirectional Hiperface protocol and can process incremental lines at the logic-level swing of 5 V TTL, enabling mixed encoder populations on the same machine. A dedicated safety circuit executes Safe Torque Off to cut drive power within milliseconds when a risk condition is detected, and a standard front operator panel together with an integrated relay output provides manual jog functions and system-ready signaling without extra hardware.
