Product Description:

The CSH01.1C-PL-EN1-NNN-MEM-NN-S-NN-FW is a single-axis motion and I/O controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It coordinates drive functions, encoder evaluation, and parallel field signals in automated machinery such as packaging stations or gantry axes. Because the internal encoder-emulation circuitry draws its supply from the controller back-plane, an external emulation supply is not required, simplifying panel wiring and reducing auxiliary power components.

During power-up the controller draws a maximum inrush of 4 A, and this surge is limited electronically to a duration of 100 ms so upstream breakers can be sized for brief overloads without nuisance trips. Once initialized, the electronics consume only 7.5 W, a value that minimizes cabinet heat. Command data from the host PLC is exchanged through a Parallel Interface, which allows the full bank of 16 digital inputs to be scanned in a single read cycle. Each input registers an ON state when the line reaches 15 V, while the 16 digital outputs can source up to 500 mA per channel for relay coils or lamp loads.

The internal emulation path is Galvanically Isolated, preventing ground loops between the drive and feedback circuits. Encoder services are versatile: the unit outputs Absolute And Incremental position formats and simultaneously evaluates Resolver And HSF signals coming from the motor sensor. These functions are powered by a dedicated rail that delivers DC 8 V / AC 18.2 Vpp to the transducer, so no external supply conditioning is necessary. Power budgeting for the option boards remains modest; the EN1 communication module requires 6 W, the MEM memory module draws 2 W, and the PL processing module adds 1 W, ensuring that even fully configured controllers stay within the overall thermal envelope established in the previous paragraph.
