Product Description:

The CSH01.1C-SE-ENS-EN2-MD1-S1-S-NN-FW is a compact high-performance motion controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Deployed as the command section inside IndraDrive systems, it handles axis regulation, I/O management, and safe shutdown tasks for production lines, packaging machines, and handling systems. By processing drive-level feedback in real time, the unit translates PLC setpoints into torque, velocity, or position commands with predictable timing. As the command section of the drive system, it centralizes motion processing and protective functions in one control platform.

Field communication with the power stage occurs via the SERCOS interface, which delivers synchronized telegrams each cycle. Setup and file transfer use a maintenance link over RS232. The current loop refreshes every 62.5 µs, the velocity loop at 125 µs, and the position processor at 250 µs, giving the controller fast internal response during axis operation. Base resources comprise one analog input, two analog outputs, and seven digital inputs for direct connection of sensors and potentiometers. Integrated I/O Safety Technology monitors selected lines and disables the drive when a fault state is detected.

For feedback devices, Encoder Interface 1 accepts IndraDyn, Hiperface, 1 Vpp, or 5 V TTL formats and supplies 11.6 V to the measuring circuit so cable drop does not affect reference signals. A second interface supports EnDat 2.1 plus the same incremental standards and supplies 5 V when mixed encoder types are used on separate channels. Slot 3 is equipped with the Digital I/O Extension card, adding 12 additional digital inputs and 8 digital outputs that appear to the controller as MD1 resources. These lines can trigger homing, report limit switches, or actuate clutches directly from the device. The dual feedback arrangement also gives the controller broad compatibility with different motor and encoder combinations used in automated machinery.
