Product Description:

The CSH01.2C-CO-ENS-EN2-CCD-NN-S-NN-FW controller card is built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It provides motion-control processing and network routing inside IndraDrive automation platforms, coordinating drives, encoders, and higher-level PLCs over real-time buses. Within an industrial cell, the card generates reference values, gathers feedback, and links to fieldbus networks so axis groups can be synchronized or independently positioned. It also serves as the central control layer inside the drive system, passing commands between the power section, connected feedback devices, and the machine-level network.

The module draws a base power of 8.5 W, allowing low self-heating when it is seated on the drive’s main backplane. A built-in bus terminator of 124 Ω, 1%, 200 mW maintains characteristic impedance on the CAN segment, so external resistors are unnecessary. On the CANopen side, the interface can address up to 127 logical nodes, while the DeviceNet stack supports up to 64 devices. This allows one controller card to communicate with multiple remote stations in distributed machine layouts. At power-up, the inrush current peaks at 4 A, so the supply circuit must tolerate a short startup surge.

For cross-communication, the card acts as a SERCOS III Master and relies on the Ethernet physical layer specified by IEEE 802.3. Engineering access is provided through an RJ-45 port working at 100Base-TX, and configuration cables can be extended to a maximum length of 100 m without repeaters. Position feedback is accepted through the EN2 connector, which handles EnDat 2.1 / 1 Vpp / 5 V TTL signals, allowing the controller to process both absolute and incremental encoder data. This arrangement lets the card manage real-time axis communication while still supporting standard Ethernet-based service access.
