Product Description:

The CSH01.3C-PB-ENS-MEM-CCD-NN-S-NN-FW controller is built by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. The unit serves as the central module in a drive package, issuing position commands, collecting feedback, and bridging higher-level PLCs with servo inverters on the same machine. By combining motion calculation, fieldbus routing, and encoder processing in one compact board, it streamlines cabinet layouts and reduces wiring in automated assembly stations, packaging lines, and material-handling gantries.

Two analog outputs are provided: one can source 1 mA, and the other delivers 5 V, letting the controller generate low-power reference signals for proportional valves or external amplifiers. A base draw of 8.5 W keeps thermal dissipation modest, so forced ventilation is rarely required. Command traffic to slave drives moves over PROFIBUS-DP, and the interface can sustain a fieldbus rate of 12 MBaud for synchronized cycle times. When axis emulation is needed, the pulse-train replicator supplies 20 mA at up to 1 MHz, which suits simulators or legacy counters. An 8-pin RJ-45 Ethernet port supports parameter download and diagnostic capture. Inrush current peaks at 4 A during power-up, and single-shot output pulses can be stretched to a maximum width of 100 ms.

Cross-device coordination between multiple CSH processors is handled by the SERCOS III Master, allowing deterministic communication for multi-axis gantries without a separate controller. Position sensors connect through the standard encoder-evaluation interface; the board supplies 11.6 V at up to 500 mA, so both absolute and incremental encoders receive stable excitation even over long cable runs. Encoder emulation logic mirrors the incoming data onto the same bus, enabling downstream drives to share a common reference without additional converters. The module combines encoder power, timing functions, and network resources in a single controller slot.
