Product Description:

The CSH01.1C-SE-ENS-EN2-EN2-L1-S-NN-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed in an IndraDrive power section, it directs a single servo axis in automated machinery by translating PLC commands into precise drive signals and collecting real-time encoder feedback. It combines communication handling, I/O processing, and safety monitoring in one module, which helps reduce cabinet wiring in assembly lines, packaging machines, and material-handling stations. This arrangement also keeps control functions concentrated in the drive platform for coordinated motion tasks.

It exchanges motion data over the SERCOS II bus and can also be accessed through an RS-232 service port. The analog input channel presents an impedance of 160 kΩ, which allows signal conditioning with minimal load on upstream sensors. For command outputs, the board can source 1 mA at an analog level of 5 V, making it suitable for reference transmission to external amplifiers. Digital inputs recognize an on-state at 15 V, while the eight high-side transistor outputs deliver up to 500 mA per point for valve coils, contactors, or status lamps. The ENS + EN2 + EN2 encoder interface set allows the controller to read incremental or absolute sensors, and each installed encoder module draws 6 W for signal processing.

Overall consumption is modest: the controller itself needs 7.5 W at idle, and a separate SERCOS communication module absorbs 2 W. The starting-lockout safety circuit requires an equal amount of power, and the digital outputs can source up to 1000 mA in total when all channels are energized, which must be considered when sizing the 24 V control supply. The built-in starting lockout satisfies the Category 0 stop profile by immediately removing drive power when a fault is detected. This hard shutoff prevents unintended motion without relying on controlled deceleration.
