Product Description:

The CSH01.1C-SE-EN2-NNN-NNN-S2-S-NN-FW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. It is a motion-control main card that coordinates servo drives, collects feedback through multiple encoder formats, and distributes setpoints over the SERCOS bus so that connected axes follow deterministic command cycles in industrial automation cells. The unit supports centralized motion supervision where several axes must exchange commands and feedback without timing drift. It combines axis coordination, feedback acquisition, and networked setpoint distribution in one control section.

The controller’s two differential analog inputs present an impedance of 160 kΩ, while each converter resolves signals to 1.23 mV/inc for precise scaling of sensor signals. One buffered analog output supplies up to 1 mA to external actuators or indicators. During power-up, the base section draws an inrush current of 4 A and then settles at a base consumption of 7.5 W. Digital switching channels can sink 500 mA and source 24 V logic for field devices, while the safety layer implements Safe Motion to support risk reduction without external relays. This combination supports sensor input and low-current analog signaling without separate interface hardware.

The EN2 secondary channel delivers 350 mA at 5.0 V and is protected by a load resistor of 35 Ω. Command traffic runs on SERCOS II, and the onboard encoder interface accepts EnDat 2.1, 1 Vpp, or 5 V TTL feedback so different feedback devices can be connected directly. Pulse-type signals are accepted to a width of 100 ms, and the base supports a 2 W SERCOS communication module that remains energized for ring redundancy. The local regulator dissipates 6 W under full encoder loading, and the RS-232 port supports service communication when network access is unavailable.
