Product Description:

The CSH01.1C-CO-ENS-EN2-NNN-S2-S-XP-FW is a control section from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Installed in a drive controller rack, it provides logic, fieldbus communication, and encoder evaluation for multi-axis drives that need coordinated motion and feedback handling. By coordinating motion commands and safety feedback, the board allows servo motors and peripheral devices to operate in sync with the machine PLC in automated assembly lines, packaging stations, and material-handling workcells.

Field communication is provided through CANopen and DeviceNet interfaces. The CANopen bus supports up to 127 addressable nodes, while the DeviceNet channel allows 64 nodes on the same trunk. Bus wiring lands on a 5-pin spring terminal, minimizing tool changes during service. Internal electronics draw only 7.5 W, reducing thermal load inside the cabinet. For high-speed position capture, the En2 incremental encoder port accepts pulse rates up to 1000 kHz and supplies the sensor from a regulated 5.0 V rail with up to 350 mA available. The companion Ens interface supplies 11.6 V at up to 500 mA for SinCos encoders and uses matching input impedance to help maintain signal quality over long shielded cables.

During power-up, the module draws 4 A of inrush current, after which normal operation continues with minimal steady current draw. Functional safety wiring connects through a D-Sub 9-pin female connector; inputs are rated at 24 V / 3 mA, and outputs can switch 24 V / 0.5 A to external contactors. The safety interface is intended for safe-torque-off circuits and related external control devices. The Ens channel uses a 120 ohm termination resistor to support stable encoder signaling. This short inrush surge is typically handled by standard control transformers and does not change the module’s low steady-state power demand.
