Product Description:

The CSH01.3C-PB-ENS-EN1-CCD-NN-S-NN-FW is a motion-control CPU card produced by Bosch Rexroth Indramat for integration in the CSH Advanced Controllers series. Installed in an IndraDrive multi-axis rack, the unit executes drive regulation and machine logic so that servo axes follow commanded trajectories with deterministic timing. It bridges power electronics and supervisory PLCs, allowing the drive stack to operate autonomously while still exchanging setpoints and status across the plant network. Because control functions run directly on the card, the rack can coordinate motion tasks locally without depending on a separate external controller for each axis.

The board provides 2 configurable analog outputs for speed or torque reference signals and draws only 8.5 W of base power, minimizing thermal load inside the enclosure. Axis and PLC data are transferred over PROFIBUS; the interface supports a maximum bus rate of 12 MBaud and terminates on a compact D-Sub 9-pin female connector, easing retrofit into existing wiring harnesses. A single-line control-panel display supplies local status, while cross-communication with neighboring drives is handled by a SERCOS III master channel to keep multi-axis interpolation synchronized. Resolver, HSF, and standard-encoder evaluation ports provide position feedback options without additional expansion cards.

The internal current loop closes every 62.5 µs, and the pulse-width modulator can switch up to 16 kHz, enabling fine torque control at high motor speeds. For service access, a 100 Mbit/s Ethernet port identified as 100Base-TX permits parameter download from IndraWorks over distances up to the stated 15 m serial cable limit. Output relays rated at DC 24 V, 1 A can actuate brakes or contactors directly, reducing I/O demand on the main PLC. Separate encoder supply rails support connected feedback devices, and the controller can manage both motion processing and machine-level signal handling within the same drive platform.
