Product Description:

The CSH01.1C-SE-EN2-EN1-MD2-S1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on a power module, it orchestrates multi-axis motion, gathers encoder feedback, and executes integrated safety functions in industrial automation cells. By combining logic processing with fieldbus communication inside the drive rack, it reduces the need for separate PLC hardware and shortens the control loop for precision positioning tasks in packaging, printing, and material-handling equipment.

The unit has a base power budget of 7.5 W for its internal processor and peripheral buses. Command exchange with higher-level motion controllers takes place over SERCOS II, so real-time telegrams reach the drives within microseconds. Local machine signals are accepted through 16 digital expansion inputs and issued through matching digital expansion outputs. These channels are presented as a Digital I/O + SSI mezzanine, allowing the module to timestamp position latches while streaming serial encoder data. The HSF interface supplies sensors with 250 mA at a regulated 8.0 VDC, supporting absolute encoders that need stable excitation during fast moves.

Primary feedback devices can draw 350 mA, and the slot accepts the EnDat 2.1 / 1 Vpp / 5 V TTL format for high-resolution position sampling. A secondary channel services resolver or HSF feedback, and it produces a 4 kHz carrier with an amplitude of 18.2 Vpp so a resolver can be connected without an external supply. For functional safety, the Safety Technology I/O circuit energizes external contactors through a rated output of 24 V / 0.5 A once all axes are in a safe state. The integrated SSI port uses an RJ12 6-pin connector and can deliver 0.2 A to an external sensor, allowing synchronous serial encoders to share the same card without extra wiring.
