Product Description:
The CSH01.1C-ET-ENS-EN2-MA1-L2-S-NN-FW is a single-axis motion controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It operates as the central processing unit in a drive package, coordinating position, velocity, and torque commands for electric servo axes over industrial Ethernet networks. This unit supports packaging, printing, and handling systems by combining master communication ports, local encoder evaluation, and safety circuitry in one compact rack-mount module.
The controller’s base demand on the control cabinet power rail is 7.5 W, so heat generation is minimal and convection cooling is usually sufficient. For primary feedback, the first encoder port provides a regulated 12 V supply and accepts standard incremental or absolute signals, allowing the drive to close its control loops without auxiliary adapters. The controller includes 11 optically isolated discrete inputs for machine states, limit switches, or external interlocks, and it also provides 4 transistor outputs for status bits or drive-ready signals. A second feedback port supplies up to 350 mA at 5 V and can decode EnDat 2.1, 1 Vpp sine-cosine, or 5 V TTL formats, allowing different encoder technologies to be used on the same axis card. All fieldbus tasks, including device configuration, cyclic process data, and diagnostics, are exchanged through the controller’s Multi-Ethernet interface, which supports EtherNet/IP, PROFINET IO, EtherCAT, and Sercos III without hardware changes.
When the application requires remote mounting of high-resolution feedback devices, the second encoder channel supports cable runs up to 75 m with sense lines to correct voltage drop, or 50 m without them. Two analog input channels and two analog output channels each feature 12-bit resolution, so speed or torque trim values can be captured and generated with 0.024% granularity across the ±10 V span. Functional safety is embedded through the certified Safe Torque Off circuit; removing its enable signal disables drive power within milliseconds and eliminates the need for external contactors.
