Product Description:
The CSH02.1B-ET-EC-EM-NN-NN-NN-FW control section is built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive compact or modular power unit, it governs servo axes, manages peripheral I/O, and coordinates Ethernet fieldbus traffic in automated assembly, packaging, and material-handling machinery. The board integrates the processor, memory, and safety logic needed for motion control without requiring an external motion card. Its integrated layout keeps the control electronics close to the drive hardware, which helps coordinate command processing, feedback handling, and I/O response within one assembly. It mounts directly on the drive backplane, receives low-voltage supply from the power section, and presents front connectors for encoder feedback and network cabling.
Primary power for the controller is drawn from a DC 24 V service line supplied by the adjacent power module. Under nominal conditions, the logic and communication circuits consume only 17 W, which limits heat buildup inside the cabinet. Two auxiliary rails are available, and the 12-volt domain can deliver 500 mA for external sensors. A separate 5-volt rail supports bus transceivers and encoder heads, allowing small peripheral devices to be supplied directly from the control section. Network integration is handled through a Multi-Ethernet interface that supports PROFINET, EtherNet/IP, and EtherCAT while remaining compliant with IEEE 802.3 signaling rules. The control section is intended for use with a compatible power section in the same drive platform.
Feedback wiring connects to an EC side connector specified as a D-Sub 15-pin female, while the motor encoder signals exit on an EM D-Sub 15-pin male plug. For the EM channel, line loading must not exceed 60 pF/m to help prevent signal distortion. When shielded cable is used, cable runs may extend to 40 m, while unshielded conductors are limited to 30 m. The synchronous serial interface can clock position words at up to 1 MHz, providing deterministic timing for high-resolution encoders. The feedback channel is intended for high-resolution encoders used on fast servo axes.
