Product Description:

Bosch Rexroth Indramat produces the CSH01.1C-NN-EN2-NNN-NNN-L2-S-NN-FW as part of the CSH Advanced Controllers series. This plug-in control section attaches to modular drive stacks and executes axis commands, processes encoder signals, and issues drive enables that synchronize motion on automated machinery. It forms the local intelligence layer between higher-level PLCs and servo inverters, coordinating status exchange across assembly, packaging, and material-handling lines. The unit is intended for modular drive systems where signal processing and axis coordination are handled directly at the control section.

The board draws a base power of 7.5 W, so thermal load inside crowded cabinets stays limited. Two analog channels can source up to 1 mA each and supply a reference of 5 V for proportional valve or speed commands. Four protected digital outputs handle field devices up to 500 mA, letting the unit drive relays or indicator lamps directly. When first energized, the section presents an inrush of 4 A, which should be considered when sizing cabinet fuses and auxiliary supplies. The controller does not include a master communication bus, so field networking is handled by the paired power module.

Feedback enters through a D-Sub 15-pin socket that supports EnDat 2.1, 1 Vpp, and 5 V TTL signals, while the dedicated En2 mezzanine dissipates only 6 W, allowing convection cooling. Position-latch or marker pulses can be generated with widths up to 100 ms, providing a broad timing window for external control functions. The integrated safety channel delivers Safe Torque Off without extra devices, simplifying Category 3 circuits. Mechanically, the module spans 49.5 mm across the DIN rail, with a depth of 103 mm and a height of 241 mm, so it aligns with standard IndraDrive supply sections while maintaining uniform cabinet spacing. This layout supports consistent installation within compact multi-axis drive assemblies.
