Product Description:

The CSH01.1C-ET-EN2-ENS-NNN-S2-S-NN-FW is a plug-in controller card built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit fits inside IndraDrive power sections and supplies motion control, logic sequencing, and real-time network interfacing for multi-axis machinery. Hosting the control loops on the drive backplane streamlines cabinet layouts and supports deterministic motion in packaging lines, printing presses, and factory automation. Because the controller resides in the drive, signal paths between the power section and the feedback interfaces remain short.

Its electronics require only 7.5 W of base power and are energized from a DC 24 V control supply routed through the host drive. The Ethernet technology section adds 2.2 W but remains within the card’s thermal budget. Two dedicated encoder buses are present: En2 operates from a 5 V rail and accepts EnDat 2.1, 1 Vpp, or 5 V TTL feedback, whereas Ens is powered by a 12 V rail and handles IndraDyn, HIPERFACE, or 1 Vpp signals. This split feedback arrangement allows the card to work with several common motor and machine encoder types without a separate feedback module. Servo accuracy is supported by a closed-loop current control cycle of 125 µs. For analog interfacing, the board offers 1 input channel for position or process variables and 2 output channels for command or diagnostic voltages. The maximum single-shot pulse that can be processed by the hardware is 100 ms, which provides an ample window for reference mark detection.

Field communication is handled by a Multi-Ethernet master that follows the 100Base-TX standard and supports cable runs up to 100 m before a repeater is needed. During power-up, the card can draw an inrush of 4 A, so input fusing must accommodate that transient. The controller also includes Safe Motion for performance-level monitoring and shutdown. Multi-Ethernet allows the same control platform to connect to different industrial Ethernet environments without changing the basic control card.
