Product Description:

The CSH01.1C-ET-ENS-MA1-MD2-L2-S-NN-FW is a single-axis motion and logic controller created by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This plug-in unit fits into IndraDrive power sections and coordinates servo axes, field I/O, and network traffic in industrial automation cells. By combining drive regulation, PLC processing, and safety in one slot, it manages machine sequences, synchronizes motion profiles, and exchanges deterministic data with plant supervisory systems. Its integrated approach allows one control platform to handle axis behavior and machine logic without requiring separate standalone motion hardware.

The controller draws a base power of 7.5 W, so heat generation inside the cabinet remains low. On initial energization, it tolerates an inrush of 4 A, which affects fuse and power supply sizing. High-speed capture tasks are supported by a probe input that reacts within 1 µs, while the internal pulse stretcher can accept events with widths up to 100 ms. Command and feedback signals enter through logic rails, and each digital input sinks 24 V DC at 3 mA while the transistor outputs source 0.5 A per channel for contactor coils, solenoids, or status lamps.

Extended process connectivity is handled by the analog board, which offers two differential inputs and two outputs with 12-bit resolution for scaled sensor readings and actuator commands. Discrete field wiring is centralized on the digital extension, which provides 16 inputs and an equal number of outputs, plus an SSI interface for encoder latching and related registration tasks. Machine networks link to the controller over MultiEthernet, allowing EtherNet/IP, PROFINET, and EtherCAT topologies without hardware changes. Functional safety is incorporated through the drive-integrated Safe Torque Off channel, permitting immediate motor torque removal to meet SIL3 and PL e risk reduction requirements.
