Product Description:

The CSH01.1C-PL-EN2-NNN-MA1-NN-S-NN-FW is a motion and logic controller module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit acts as the primary command layer in multi-axis drive assemblies, converting automation program instructions into coordinated electrical signals for servo drives and feedback elements in industrial machinery. It integrates analog, digital, and encoder channels to supervise velocity, position, and diagnostic data across the automation cell while coordinating communication between the control section and connected axes. Because the module combines these channels in one controller, external interface hardware can be reduced in compact automation cabinets.

Two differential analog inputs accept signals in a range of ±10 V, and a front-end impedance of 1000 kΩ minimizes loading on process transducers. These inputs are sampled with a resolution of 12-bit to preserve fine setpoint granularity. The controller also provides two analog outputs that can source up to 10 mA across the same ±10 V span, allowing drive reference or actuator feedback generation. Command and diagnostic data reach the module through the Parallel Interface, which supports deterministic timing for high-speed machine cycles. For sine-cosine or TTL position sensors, the encoder input stage presents a termination of 120 Ω, helping maintain signal integrity over long shielded cables.

Sixteen independent parallel inputs and sixteen parallel outputs handle interlocks, limit switches, and status lamps without external expanders. The integrated encoder port supports EnDat 2.1; 1 Vpp; 5 V TTL formats and supplies the transducer with a regulated 5 V rail. For shaping internal control loops, the sine channel maintains accuracy up to 500 kHz, while square-wave measurement extends to 1000 kHz. Matching analog-to-digital and digital-to-analog performance helps the controller process incoming references and return output commands with consistent granularity. Separate parallel I/O and encoder feedback paths let the controller react to discrete machine events without interrupting continuous position processing. The module exchanges motion data and machine-state signals in real time during synchronized axis control.
