Product Description:

The CSH01.1C-PB-ENS-NNN-MD2-S1-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is a single-axis control section used in modular drive stacks to process encoder feedback, fieldbus commands, and local I/O so that an IndraDrive power module can execute precise motion profiles in industrial automation cells. A standard front control panel supports parameter entry for local setup and status review.

This control section communicates with higher-level PLCs through PROFIBUS, giving it deterministic master access for setpoints and diagnostics. Two differential analog inputs accept signals up to ±10 V, and their 160 kΩ input resistance minimizes loading on external transducers. The module also generates reference values through an analog output that can reach 5 V at a maximum sink of 1 mA, which is suitable for speed or tension loops that still rely on voltage control. The built-in digital I/O expansion offers 16 inputs and 16 outputs to map proximity switches or interlocks without extra hardware. Configuration data can be stored in the X7 memory card slot for local data retention. Position feedback is handled by a multi-protocol encoder interface that recognizes IndraDyn, HIPERFACE, 1 Vpp, or TTL formats, and an SSI evaluation circuit is included for absolute position sensors.

The discrete output block can switch inductive loads rated at 24 V 0.5 A, and a separate relay contact supports control signals up to 24 V DC at 1 A. Overall device size is kept to 241 × 103 × 49.5 mm, allowing two units to fit side by side in a 300 mm deep cabinet. Safety Technology I/O is available through the front panel, and safe stop or guard door circuits terminate on the rugged D-Sub 9 female connector. A computer can access diagnostic and trace data through the integrated RS232 service port.
