Product Description:

The CSH01.1C-PL-ENS-MA1-MD2-S1-S-NN-FW is a plug-in control section supplied by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Positioned between the higher-level PLC and the IndraDrive power stage, it executes motion commands, manages feedback, and supervises drive safety. By integrating logical processing, analog conversion, and field-level I/O on one board, the unit streamlines cabinet layouts and reduces wiring effort in packaging machines, pick-and-place lines, and general automation cells. Its role is to interpret incoming commands and pass coordinated control data to the drive so axis behavior remains consistent during rapid motion sequences and process changes.

Command data are transferred through a Parallel Interface, giving deterministic update times for synchronized multi-axis moves. The controller accepts position feedback from IndraDyn S, HIPERFACE, EnDat 2.1, and 5 V TTL encoders, so a single hardware type can support several motor technologies. That flexibility is useful when one machine platform uses different feedback devices across separate axes. Machine pressures, tensions, or temperatures can be sampled through two differential ±10 V analog input channels, while status bits flow through 16 inputs and 16 outputs. All extension connections are galvanically isolated, which separates sensor grounds from drive power and minimizes crosstalk when long cables are routed alongside power conductors.

The same extension module produces two ±10 V analog outputs for drive setpoints and is fed from a DC 19 to 30 V auxiliary rail; load capability on the digital side reaches 24 V / 0.5 A per output group. Conversion accuracy across every analog path is 12 bit, supporting precise trimming without external converters. Low-level references for potentiometers or resolver supplies are provided by 2 x 5 V / 1 mA outputs on the base board. Safety logic is hardware-based and can assert standstill, drive interlock, reduced speed, and direction states when commanded by isolated control signals. An SSI evaluation channel for absolute encoders is already populated, which reduces the need for an additional option card in systems that use that feedback method.
