Product Description:

The CSH01.2C-PL-ENS-EN2-CCD-L1-S-NN-FW is a control section from the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It is installed on an IndraDrive power unit as the upper control electronics module. The control section manages the functions that coordinate the drive with the rest of the machine. In operation, it handles axis regulation, field communication, and encoder processing so servo drives can follow PLC sequences precisely in production lines and material-handling cells.

At the controller backplane, command data are exchanged through a Parallel Interface, which removes network latency between the control and power electronics. For drive-to-drive communication, the card relies on the IEEE 802.3 Ethernet standard, and the controller operates as a SERCOS III Master so multiple axes stay synchronized in real time. That communication structure supports tightly timed exchange between coordinated axes on the same machine. A computer can connect to the engineering port that supports 100Base-TX; the physical connector is an RJ-45, 8-Pin jack that accepts standard patch cables. A separate RS-232 serial interface, brought out on an 8-pin Mini-DIN, remains available for legacy diagnostics. The front-mounted single-line display provides basic status information without an external interface.

Local machine wiring is simplified by the digital I/O block that offers 16 DI / 16 DO for sensors, interlocks, and small actuators. The inputs can monitor machine conditions, while the outputs can switch small control signals to connected devices. Primary position feedback enters through the 15-Pin D-Sub Female connector, and signals are processed by a 12 V Encoder Evaluation circuit sized for standard TTL or sine-cosine sensors. The secondary encoder channel provides a 5 V supply at 350 mA and accepts EnDat 2.1, 1 Vpp, or 5 V TTL formats, allowing a second feedback source when the application requires it. This arrangement allows motor feedback and an additional measuring channel to be processed by the same unit. Motion is inhibited until the starting lockout safety function is cleared, and on an emergency stop the drive obeys Category 0, removing energy immediately.
