Product Description:

The CSH01.1C-SE-EN1-EN2-EN2-NN-S-NN-FW is an advanced motion controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the central processing and interface card inside Rexroth drive packages, coordinating encoder feedback, digital I/O, and fieldbus links so downstream inverters follow commanded positions and speeds in industrial automation cells. An asynchronous maintenance port supports RS-232 communication for parameter backups and direct setup access, giving the controller a dedicated channel for service tasks without interfering with the main motion network.

Within its circuitry, the module draws a maximum configured power of 27.5 W, which helps size the auxiliary supply feeding the card. All onboard sensors and actuators share an I/O bus held at 24 V DC, and that rail can deliver up to 1.1 A for external loads through pluggable terminals. Individual transistor outputs are limited to 500 mA each, which helps prevent overheating during high-side switching. Incoming digital signals reach their logic on state once they exceed 15 V, and the board provides a calibrated reference of 5 V for potentiometric speed or torque commands.

Motion feedback and real-time fieldbus timing are managed by separate channels so control tasks remain organized within the card. The primary encoder connector excites the resolver with a carrier of 4 kHz and senses rotation through a differential amplitude of 18.2 Vpp, giving precise shaft-angle data even under electrical noise. A secondary encoder socket supplies 8 V while the EN2 interface distributes 5 V for incremental sensors, so mixed feedback types can share the same card. When synchronized control loops across multiple drives are required, the integrated Sercos III interface streams data at up to 16 MBaud, and its relay contact rated at 1 A provides a simple hardware-ready output to higher-level safety circuits.
