Product Description:

The CSH01.1C-SE-EN2-NNN-NNN-L2-S-NN-FW is a single-axis control section built by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for installation on IndraDrive platforms, the unit supervises motion of servo drives in automated machinery, providing setpoint processing, real-time feedback handling, and integrated safety. By linking field devices to higher-level machine PLCs, it coordinates positioning, speed regulation, and torque limitation functions in industrial automation cells.

The control section governs 1 drive axis and exchanges cyclic data with the power stage over the fiber-optic SERCOS II channel that operates at a communication rate of 16 MBaud. Diagnostic access and parameter backup can also be performed locally through the integrated RS232 serial interface. Its EN2 encoder port uses a D-Sub 15-pin female connector; this interface supplies the encoder with 5.0 V at up to 350 mA and expects a terminating load of 35 Ω, enabling feedback formats such as EnDat 2.1, 1 Vpp, or 5 V TTL. During power-up, the assembly draws an inrush current of 4 A. Internal logic allows a maximum output pulse width of 100 ms for trigger functions.

The module consumes only 7.5 W while active, so thermal loading inside a control cabinet is minimal. All logic circuits are fed from a DC 24 V source, and a matching relay output is rated for 24 V DC at 1 A to drive status lamps or interlock coils. For machine safety, the integrated SafeMotion circuitry provides a hardware-based Safe Torque Off channel that disables drive energy within a few milliseconds when the monitored enable path opens. The control section combines low power draw, encoder excitation, relay signaling, and hardware-based torque shutdown in one unit.
