Product Description:

The CSH01.1C-ET-EN1-NNN-MD2-L2-S-NN-FW is a single-axis motion and logic controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It coordinates drive functions, feedback evaluation, and fieldbus traffic in automated machinery, acting as the command layer between higher-level PLCs and the servo inverters it supervises. Through its integrated electronics and modular add-on card slot, the unit streamlines panel space while providing deterministic control for packaging lines, material-handling stations, and similar equipment.

Its control core runs from a base supply of DC 24 V, drawing only 7.5 W when idle, so panel heat dissipation remains minimal. The I/O back-plane is fed by up to 1.1 A, allowing sensors and encoders to be powered directly without external converters. During power-up, an inrush of 4 A must be considered when sizing circuit breakers. Communication with higher networks is handled by the integrated MultiEthernet port, giving simultaneous access to EtherNet/IP, PROFINET, and EtherCAT telegrams. Position feedback is accepted through HSF or RSF incremental interfaces, and an 8 V line supplies encoders separately from the logic rail. For time-critical triggers, the MD2 circuitry can output pulses as short as 100 ms, letting the controller toggle clutches or solenoids on fast machine cycles.

The MD2 expansion provides 16 sinking inputs arranged in two isolated banks and 16 sourcing outputs grouped in four blocks. Each output can switch loads up to DC 24 V and 1 A. Functional safety is addressed by the integrated Safe Torque Off channel, which disconnects drive power inside the servo amplifier without delaying fieldbus communication. Cabinet layout is aided by the compact form factor: the housing is only 103 mm deep, 49.5 mm wide, and 241 mm tall so several axes can be installed side by side. With 16 digital outputs available at the terminal strip, the controller can actuate valves, brakes, or pilot relays directly, reducing auxiliary wiring and simplifying machine documentation.
