Product Description:

The CSH01.3C-PB-EN2-MA1-CCD-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is a modular drive controller card intended to coordinate servo axes and field devices inside automated machinery. By handling real-time motion calculation and network traffic, the unit forms the interface between higher-level PLC equipment and the power stages that drive motors, thereby streamlining start-stop sequences, position loops, and diagnostic feedback in production lines.

During operation, the card draws a base power of 8.5 W, a low figure that limits heat generation inside a multi-axis cabinet. Master fieldbus exchange is handled through PROFIBUS-DP, while plant-wide cross communication follows the Ethernet standard IEEE 802.3; this split lets the controller separate deterministic motion traffic from non-real-time data, and parameterization is carried out through an Ethernet-based engineering port. Feedback from rotary or linear encoders is accepted through a single interface that supports EnDat 2.1 / 1 Vpp / 5 V TTL, simplifying retrofit work. For local signaling, the digital I/O rail can source up to 1.1 A, enough to feed sensors, optocouplers, or small relays without external power supplies.

An analog extension board adds two input and two output channels. Each input accepts a ±10 V input range, and each output can supply the same swing for drive-level torque or speed commands. Conversion is performed with a 12-bit resolution, giving 4096 discrete steps that align with common drive tolerances. A metallic 9-pin D-Sub connector carries the PROFIBUS wiring, and the integrated relay contacts switch loads rated at DC 24 V, 1 A for alarms or interlocks. Additional design allowances include a 5 V encoder supply, onboard analog outputs limited to 5 V, and encoder cable lengths of 50 m without sense lines or 75 m when sense wiring is used.
