Product Description:

The CSH01.1C-NN-EN2-EN2-NNN-L2-S-NN-FW is a motion-logic controller module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It mounts in IndraDrive power sections to coordinate axis positioning, velocity control, and diagnostic feedback across automated machinery. By combining analog measurement, digital I/O, and multi-protocol encoder support, the board acts as the command layer between higher-level PLCs and the drive power electronics in assembly, packaging, and material-handling lines. This arrangement allows the controller to process incoming reference signals, evaluate feedback data, and pass coordinated commands to the power stage without requiring a separate standalone motion processor.

Its analog input impedance is 160 kΩ, so the module minimally loads connected sensors and helps prevent signal distortion. The analog output stage provides 5 V / 1 mA for drive reference signals, and its resolution is 19.5 mV/inc, which supports fine setpoint adjustment. For discrete signals, each digital input expects 24 V / 3 mA, while each digital output can source 24 V / 0.5 A for relays or indicator lamps. The board also includes encoder interfaces for closed-loop feedback, including two EnDat 2.1 channels plus 1 Vpp and 5 V TTL readers. An RS232 node supports point-to-point diagnostics over short cable runs when no network communication option is installed, which gives the module a direct serial path for setup access and status review.

The unit draws its logic power from a DC 24 V control bus, and during startup the cabinet supply must support an inrush current of 4 A. Under steady operation, it dissipates only 7.5 W, which helps limit heat buildup in dense multi-axis enclosures. The integrated Safe Torque Off function disables the drive output stages while allowing encoder monitoring to remain active for feedback supervision. A form-C relay is available for drive-ready signaling, and a standard control panel provides local access to operating parameters. This layout supports straightforward integration in systems that need local status indication, serial diagnostics, and coordinated motion control from a compact controller module.
