Product Description:

The CSH01.1C-SE-ENS-EN1-NNN-S2-S-NN-FW is a motion control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit plugs into a compatible power module and supplies the axis with command processing, signal conversion, and diagnostic handling required for automated machinery. Within an industrial cell, it accepts process references, generates drive setpoints, and relays status information to the supervisory controller, allowing tight speed, torque, and position regulation without adding a separate stand-alone PLC. This embedded design keeps wiring short and reduces electromagnetic interference inside the cabinet.

The analog front end handles sensor and reference voltages from -10 to +10 V; this span is captured as ±10 V and is suitable for velocity or pressure transducers. Incoming signals encounter an input resistance of 160 kΩ, which helps minimize loading errors, and they are digitized with 12-bit resolution for proportional closed-loop control. The controller can reissue processed commands on an output channel that swings across the same analog range and can drive a typical load of 2 kΩ. Discrete automation components are connected through IEC logic that follows the IEC 61131 Type 1 classification, while actuators such as contactors or indicator lamps can be energized directly by a digital stage rated at 24 V / 0.5 A.

Low-power circuitry on the board is fed by an ENS rail of DC 11.6 V that may supply up to 300 mA, isolating the logic from higher field voltages. A form-C relay is integrated for general-purpose signaling and can switch loads up to DC 24 V / 1 A. Encoder Interface 1 supports standard incremental or absolute formats, and Encoder Interface 2 evaluates resolver and HSF feedback, enabling mixed-motor installations. Parameter access is provided through the standard control panel, while deterministic drive coordination is exchanged over the SERCOS master link. Safe Motion technology is embedded so certified stop, speed, and direction limits can be executed without external safety relays.
