Product Description:

The CSH01.3C-ET-ENS-MA1-CCD-L2-S-NN-FW is a plug-in motion-logic controller card developed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It fits into IndraDrive modular drive stacks and delivers high-speed axis control, enabling coordinated positioning, velocity, and safety management within industrial automation cells. The card combines fieldbus, encoder, and analog channels so connected drives receive synchronous commands and feedback without requiring separate stand-alone PLC hardware.

Its MA1 option slot exposes two differential analog inputs and two analog outputs. Each channel operates across a ±10 V span, and the converter’s 12-bit resolution allows 4,096 discrete steps for process setpoints or sensor feedback. Internal electronics draw only 8.5 W at base load, which helps limit cabinet heat during continuous operation. Network traffic is handled through a Multi-Ethernet interface that supports EtherCAT, PROFINET, EtherNet/IP, and Sercos over a single port. For encoder loops, the board sources up to 500 mA of stabilized 5 V to IndraDyn, EnDat 2.1, HIPERFACE, 1 Vpp, or 5 V-TTL transducers while maintaining a differential input resistance of 120 ohms to reduce line reflection.

High-speed capture and compare tasks use a maximum pulse width of 100 ms and a TTL input bandwidth of 400 kHz, so drive events such as registration marks or torque-proving switches are processed within one control cycle. Functional safety is integrated, and the SafeX interface routes the Safe Torque Off signal through a D-Sub 9-pin female connector. When the module powers up, the supply momentarily reaches a 4 A inrush current, after which RS-232 service access becomes available for diagnostics. The card also detects two MA1 analog channels automatically and maintains correct scaling during typical surge events.
