Product Description:

The CSH01.1C-PB-ENS-EN1-MD1-L1-S-NN-FW is a drive and motion controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit oversees axis coordination, parameter handling, and fieldbus communication for automated machinery such as packaging stations and material-handling cells. By combining axis feedback interfaces with fieldbus circuitry, the controller works as the central command layer between PLC logic and IndraDrive power sections, providing deterministic command sequences and diagnostics over a single module footprint. This arrangement allows one control module to manage both motion-related data and machine-level signal exchange without requiring separate interface hardware for each task.

During operation, the controller’s base electronics draw 7.5 W, so internal heat generation stays low and cabinet ventilation requirements remain modest. Field communication is handled on a PROFIBUS interface that can exchange cyclic data at a bus speed of 12 MBaud, which supports high-speed motion profiles without exceeding typical cable lengths. Machine sensors connect through twelve opto-isolated channels, and the controller scans these 12 digital inputs every cycle to detect position switches or safety gates. Eight transistor outputs drive contactors or pilot lamps, and the controller can refresh the 8 digital outputs within the same bus update. At power-up, the supply must tolerate an inrush of 4 A, after which the controller reverts to nominal consumption. A single-line display shows status codes when the standard front panel is used. The opto-isolated input design also helps separate field-level signals from the control electronics, which supports stable signal handling in electrically noisy industrial cabinets.

Two feedback channels give the module versatility for different motor families. Channel one delivers a stabilized 12 V supply to IndraDyn and HIPERFACE transducers and accepts differential 1 Vpp signals for precision positioning. The second channel provides 8 V to resolver or HSF sensors, allowing retrofits of older axes without external adapters. This dual-channel approach lets the same controller support both newer high-resolution feedback devices and older sensor types in mixed-machine installations. For time-critical triggering, the controller can generate output pulses up to 100 ms wide, which suits valve actuation and dwell-time marking tasks. The integrated safety layer labeled Starting Lockout prevents uncontrolled motion by blocking drive enable lines until all prerequisites are met.
