Product Description:

The CSH01.3C-PL-EN2-NNN-CCD-NN-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Housed in an IndraDrive rack, it forms the signal-processing core that links drive power modules with machine-level I/O. This arrangement allows precise motion coordination, status monitoring, and parameter handling in industrial automation cells.

This unit drives its single analog output up to 5 V with a sourcing capability of 1 mA, enabling reference signals to external actuators or sensors. Position or speed commands change in discrete steps of 19.5 mV/Inc, a resolution suited for fine control loops. All digital field devices draw control power from an internal rail rated at 24 V DC, and the board can supply a maximum of 1.1 A on this rail, so PLC input cards or contactors attached directly to the section remain energized without an auxiliary supply. The serial interface is RS-232, supporting one node over cable runs up to 15 m. This link is typically used for service laptop access when fieldbus traffic is not available.

For real-time axis coupling, the cross-communication port operates as a master that follows the IEEE 802.3 standard, exchanging position data through copper lines at 100Base-TX speeds. The same Ethernet hardware is exposed on an RJ-45 eight-pin engineering port, giving setup software a dedicated channel that does not interfere with motion telegrams. Parallel machine wiring is reduced by the local I/O block that accommodates 16 Inputs, 16 Outputs, and these signals travel through the backplane directly to the drive processor. Encoder feedback choices include EnDat 2.1, 1 Vpp, and 5 V TTL formats, so the controller can close loops on resolvers or optical encoders without external converters. Safety functions are not integrated, letting designers add discrete safety relays only where required by the application.
