Product Description:

The CSH01.3C-S3-ENS-ENS-CCD-S2-S-NN-FW is a motion and I/O controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. In multi-axis automation cells, this unit coordinates drive functions, safe states, and field communication while acting as the central command card mounted in an IndraDrive power section. Cross-communication with neighboring IndraDrive cards is provided by the CCD option.

Its analog interface is built around a 12-bit digital-to-analog converter that delivers voltage commands across a bipolar ±10 V span. Two dedicated channels let the PLC transmit speed or torque setpoints directly to the drive stage, and the presence of 2 analog outputs eliminates the need for supplementary boards in smaller machines. On the primary fieldbus, a Sercos III communication module provides 100 µs cycle times and automatic device addressing, so axis parameters stay synchronized across the ring. The board also carries dual ENS encoder modules, and each input is routed through a D-Sub 15 female connector that can supply 11.6 V at 500 mA to feedback devices. Encoder data are forwarded to the drive CPU with hardware time stamping so that position latency stays below one sample interval.

The safety layer is handled by the Safe Motion module, enabling certified stop, limited speed, and controlled direction functions without extra relays. The S3 link follows the 100Base-TX Ethernet standard and terminates on two RJ-45 eight-pin sockets. Compact dimensions aid dense cabinet layouts because the board occupies only 49.5 mm in width, 241 mm in height, and 103 mm in depth, allowing several axes on one DIN rail. A Mini-DIN eight-pin serial port supports service access and diagnostics without disturbing the real-time network, and the encoder supply current of 500 mA is delivered through short internal traces to keep heat localized during continuous operation.
