Product Description:
The CSH01.1C-SE-EN2-NNN-MEM-L2-S-NN-FW is a single-axis motion controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit is installed on Rexroth drive racks to coordinate servo and spindle functions in automated machinery, packaging cells, and material-handling stations. By handling high-speed position loops and fieldbus messaging in the same module, the controller serves as a compact command layer between a master PLC and the individual power stages that drive the motors.
Its analog section provides an input span of ±10 V, allowing proportional command signals from external sensors or supervisory drives. The input path presents 160 kΩ of resistance, so it loads the source only minimally and preserves signal fidelity. For drive-side feedback or trim functions, the controller delivers a reference level of 5 V and can source up to 1 mA, which is sufficient for potentiometric circuits or incremental encoders that need a low current bias. Real-time set-point data and status words are exchanged over the SERCOS II fiber-optic ring, which provides deterministic cycle times and electrical isolation from cabinet noise.
The controller also carries two probe inputs for edge-triggered position capture and a relay contact that can switch DC 24 V at 1 A for auxiliary signals. Its transistorized digital outputs can drive loads up to 0.5 A, supporting brake solenoids or indicator lamps without external relays. The secondary En2 encoder socket tolerates a load of 35 Ω and can source 350 mA from its internally regulated 5.0 V rail, so high-resolution incremental sensors remain powered during rapid traverses. A memory channel clocks diagnostic data at 1 MHz and supports the EnDat 2.1, 1 Vpp, and TTL formats available on the main encoder interface. The integrated safety layer provides Safe Torque Off, allowing drives to remove motor energy without affecting fieldbus communication.
