Product Description:

The CSH01.1C-SE-EN2-ENS-NNN-S1-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is a modular control section for mounting inside IndraDrive drive stacks, where it handles axis logic, encoder evaluation, and fieldbus communication for coordinated motion. Its position in the drive stack keeps motion-control functions close to the power section and connected feedback devices. By combining communication links, encoder interfaces, and integrated safety channels, the unit supports centralized machine control in industrial automation cells that require deterministic position and speed control.

The controller operates from a base supply of 24 VDC and draws only 7.5 W, so cabinet thermal loading remains low. At power-up, the input can momentarily reach a typical inrush current of 4 A for 100 ms, which should be considered when selecting upstream protection and power capacity. Real-time motion data is exchanged over the SERCOS II fiber-optic bus, allowing cycle-synchronous updates without external gateways. This communication link also supports controller-driven diagnostics while maintaining tight timing between multiple axes. This helps the drive coordinate synchronized motion with predictable update behavior across the system.

The CSH01.1C variant includes an EN2 interface that operates with a load resistance of 35 ohms, uses 5.0 VDC, and supplies up to 350 mA to the connected incremental encoder. For absolute feedback, the ENS channel has an input resistance of 120 ohms, uses 11.6 VDC, and supplies 500 mA for protocols such as Hiperface. Both channels accept differential signals to improve noise immunity in high-power environments. A Safety Technology I/O layer adds dual-channel emergency-stop relays rated at 24 VDC and 1 A, and it provides 0.5 A electronic outputs for safe torque off.
