Product Description:

The CSH01.1C-NN-ENS-EN2-NNN-L1-S-NN-FW module is issued by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as a control section that links encoder interfaces, logic inputs, and analog references to the associated power inverter, establishing closed-loop motion control inside automated machinery. By combining power-up supervision, encoder supply regulation, and signal conditioning, the unit coordinates axis positioning tasks and transmits status information to higher-level PLCs in industrial automation lines.

The controller is powered from a DC 24 V control supply, and its internal electronics draw only 7.5 W under steady operation, limiting cabinet heat load. At start-up, the supply must tolerate an inrush of 4 A that lasts approximately 100 ms before returning to nominal current. Separate logic inputs marked L1 accept 24 V signals and demand just 3 mA, conserving I/O power budgets. The ENS digital input path supports TTL edges up to 400 kHz, so rapid position references can be captured without loss. For physical safety, the design keeps the inrush interval short while maintaining a low continuous load, allowing compact power supplies and simplified thermal management.

The analog command port delivers a precision reference of 5 V and is rated for an output current of 1 mA, suitable for velocity or torque setpoints. Encoder support is divided between two outputs: the ENS channel furnishes 11.6 V at 500 mA for sine-cosine devices, while the EN2 channel supplies 5.0 V at 350 mA for TTL encoders. Permitted EN2 cable distances reach 50 m without sense lines and 75 m when sense conductors are used, maintaining signal integrity over long drag-chain runs. These power and cabling allowances enable the controller to feed multiple feedback formats while minimizing external power conditioning hardware.
