Product Description:

The CSH01.1C-ET-EN2-NNN-NNN-NN-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive stack, the board executes real-time position, velocity, and torque loops while also managing discrete and analog I/O. By combining motion computation with fieldbus connectivity, it synchronizes servomotors, sensors, and higher-level PLCs in packaging, printing, and material-handling systems.

At the network layer, the board supports Multi-Ethernet communication, allowing EtherNet/IP, PROFINET, or Sercos over Ethernet to be selected in software. Parameter editing is handled through the 100Base-TX engineering port. A startup surge of 4 A is the inrush current that upstream supplies must accommodate before the controller settles at a steady base consumption of 7.5 W. Two analog channels can source up to 1 mA each at a nominal 5 V, enabling reference signals to external amplifiers. Digital inputs recognize a logic high once 15 V is applied, while digital outputs can sink or source up to 500 mA for relay coils or indicator lamps. The ET communication module contributes 2.2 W to the thermal load, and the EN2 encoder module requires 6 W.

The encoder interface accepts feedback through the EnDat 2.1 / 1 Vpp / 5 V TTL format and drives the transducer across 35 ohms of load resistance with 350 mA of supply current and a regulated 5.0 V output. Pulse-train commands are supported up to 100 ms in width, enabling velocity-controlled axes to latch quickly without retrigger errors. System wiring is simplified by the service port, which reaches devices up to 15 m away for setup or diagnostics. When both plug-in modules are installed, the controller’s thermal budget rises by 8.2 W, and that load must be considered in cabinet airflow calculations.
