Product Description:

Bosch Rexroth Indramat manufactures the CSH01.3C-ET-ENS-NNN-CCD-NN-S-NN-FW as part of its CSH Advanced Controllers series. The unit is a compact motion and logic module that plugs into IndraDrive power sections, giving the drive system real-time trajectory calculation, axis coordination, and I/O supervision. By acting as the central processor for servo stages, it lets machine builders implement deterministic motion cycles in industrial automation cells such as palletizers, converting equipment, and high-speed pick-and-place stations without adding a separate PLC.

The controller’s analog front end samples process variables up to 1.4 kHz, so feedback signals from load cells or potentiometers are captured with sub-millisecond latency. An input impedance of 160 kΩ minimizes sensor loading, while the output path uses 5 kΩ resistance so external actuators see a predictable source impedance. Command voltages are produced with a granularity of 19.5 mV/inc, allowing the drive to generate fine torque references. Digital channels use a nominal input level of 24 V, 3 mA and can source up to 24 V, 0.5 A on the output side, so limit switches and small solenoids can be wired directly without auxiliary relays.

System overhead is modest at 8.5 W, letting the board run cool inside densely populated cabinets. It delivers an encoder supply of 11.6 V at up to 500 mA, which is adequate for absolute multi-turn sensors that need higher current during initialization. Field connectivity is handled through Multi-Ethernet for host control and SERCOS III for drive-to-drive communication, keeping motion data synchronized within a few microseconds. A form-C relay rated at DC 24 V, 1 A can interface with safety chains, and the built-in serial port supports diagnostics up to 115 kBaud when legacy tools are required.
