Product Description:

The CSH01.1C-SE-ENS-ENS-MD2-NN-S-NN-FW is a drive and I/O control card from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed in IndraDrive servo systems, the card supervises axis motion, gathers field signals, and exchanges real-time data with higher-level PLCs. Its role in industrial automation is to close the current loop for a connected power section while routing communication and sensor information through the drive network. In practical use, it links the servo power stage, feedback devices, and machine-level control within one platform.

Communication is handled through the SERCOS protocol on a fiber-optic link, allowing deterministic transfers at a bus speed of 16 MBaud. The network can run with a minimum cycle time of 1000 µs, so position, status, and command data are refreshed at regular intervals, while the internal current control loop updates every 125 µs to shape motor torque between bus scans. A single-line display provides local diagnostic text, and a dedicated RS-232 service port supports cable runs up to 15 m for local setup and troubleshooting. This arrangement supports synchronized multi-axis operation and direct service access without adding a separate communication gateway.

Signal conditioning is integrated through local analog channels, sixteen Md2 digital inputs, and sixteen digital outputs for nearby sensors and machine devices. The digital outputs can source up to 0.5 A per channel, and the inputs draw only 3 mA, so standard proximity sensors can be wired directly. The Md2 section also evaluates SSI feedback for connected equipment. Primary position data enter through the ENS encoder interface, which supplies 11.6 VDC at 500 mA. With 2 analog output channels available, the controller can handle secondary control tasks such as tension or temperature regulation without a separate remote I/O rack.
