Product Description:

The CSH01.1C-S3-EN2-NNN-MD2-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive inverter rack, it coordinates servo axes and manages integrated safety so that production lines, packaging machines, and material-handling cells receive synchronized motion commands and shutdown signals when required. It is intended for applications that need motion control and safety-related functions to operate within the same drive platform.

This unit’s base demand on the cabinet supply is 7.5 W. Two internal option channels add 6 W on the EN2 slot and 1 W on the MD2 slot, which helps with cabinet power and heat planning. Fieldbus traffic reaches the controller through SERCOS III, allowing deterministic communication with drives and PLCs. Feedback from motors is accepted over a multi-protocol interface that supports EnDat 2.1 / 1 Vpp / 5 V TTL, which allows use with different encoder types. The logic provides a regulated 5 V supply for encoders, so no separate external encoder power tap is required. Machine status signals enter through 16 digital expansion inputs, and the expansion outputs are arranged to support connected actuators in the same control structure.

Cable runs between the controller and servo drives can reach 75 m when sense conductors are used, or 50 m without them, which gives more flexibility in larger machine layouts. Functional safety is integrated through Safe Torque Off, which disconnects drive power when its two-channel circuit receives a permissive signal. That circuit requires a control level of DC 24 V / 3 mA and can energize external contactors up to DC 24 V / 1 A. SSI encoder support also allows absolute position detection for axes that do not use EnDat feedback.
