Product Description:

The Bosch Rexroth Indramat CSH01.1C-SE-ENS-EN1-EN2-S1-S-NN-FW belongs to the CSH Advanced Controllers series. It is a modular motion control section intended for installation inside automation systems where it commands servo drives on a single mechanical axis. The module uses a mixture of digital and analog I/O resources to coordinate position, velocity, and torque functions in industrial equipment.

Inside the controller, the current loop is closed every 125 µs, giving the drive fine-grained torque regulation for applications that need tight response. Communication with the higher-level PLC travels over the SERCOS II fiber ring, and the interface can supervise 1 axis. 2 analog outputs are available for speed references or process feedback, while each digital output can source 500 mA per channel for actuating relays. The digital inputs recognize an ON level at 15 V, so 24 V field wiring is accepted without signal adapters. A secondary logic rail provides 5 V to external sensors connected through En2, and the first encoder socket supports standard incremental evaluation. The ENS header can deliver 500 mA to supply those feedback devices without an auxiliary supply.

For higher-resolution position capture, the second encoder path evaluates resolvers through a 4 kHz carrier, and the third port accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals. The ENS rail is energized by an 11.6 V internal source that remains active during fieldbus resets. Diagnostic access over the service port reaches 115 kBaud, allowing rapid parameter backups. Functional safety is handled by the Safety Technology I/O option so emergency-stop chains can be hard-wired to the card. On the motion network, the module can accept new setpoints every 1000 µs, aligning its minimal SERCOS cycle with the deterministic current loop for consistent axis behavior.
