Product Description:

The CSH01.2C-PL-ENS-ENS-CCD-NN-S-NN-FW is an automation controller board manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed as a drive and motion coordination module, it manages axis feedback, fieldbus links, and local I/O so that connected servo inverters execute precise speed and position commands. In multi-axis cells, the unit acts as the command layer between higher-level PLCs and the individual drives, converting program data into deterministic pulses for real-time industrial processes. This arrangement lets the controller coordinate motion logic centrally while the connected power stages remain focused on motor current control.

During operation, the controller draws only 8.5 W at idle, which limits cabinet heat and auxiliary supply sizing. Its primary data path to the drive bus is a Parallel Interface, allowing direct high-speed word transfers without serialization delays. For inter-controller coordination, it serves as a Cross-Communication Master and sends deterministic frames on the IEEE 802.3 medium. Service access is provided through the 100Base-TX port for setup and diagnostics. Motion feedback is captured through two differential lines, and a pair of D-Sub 15 female encoder ports preserves signal quality under industrial noise. Separate service and control paths help keep maintenance traffic from interfering with time-critical motion exchange.

At the electrical level, the ENS sensor supply delivers 12 V, supporting external encoders or limit switches that require a regulated auxiliary rail. During startup, the module can draw 4 A of inrush current, so upstream protection must accommodate the brief surge. Each digital output channel can source up to 500 mA, while the entire output group is limited to 1000 mA; pulse trains on these lines may be stretched to a maximum width of 100 ms for actuator drive. The controller provides 16 parallel inputs and 16 parallel outputs, allowing direct wiring of photoelectric sensors or contactors without remote I/O blocks. Serial maintenance traffic is handled through an RS-232 port rated at 115 kBaud over cable runs up to 15 m, supporting parameter backup without occupying the Ethernet service connector. This local connectivity is useful when basic machine signals do not justify a separate distributed I/O station.
