Product Description:

The CSH01.3C-ET-EN2-MA1-CCD-NN-S-NN-FW is a control section developed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It installs beside IndraDrive power units and supplies motion, logic, and communication services to automated machinery. By combining Multi-Ethernet networking, an MA1 analog module, and an EN2 encoder channel in one slot, the device coordinates servo axes, handles process I/O, and links the drive system with supervisory PLC or SCADA layers used in plant automation.

Its base electronics consume only 8.5 W, so cabinet cooling requirements remain modest. When the drive stack is energized, the section momentarily draws 4 A of inrush current, and this transient value must be considered when selecting fuses and contactors. For real-time traffic, the integrated port supports 100Base-TX Fast Ethernet and participates in Multi-Ethernet protocols as the cross-communication master. The MA1 front end accepts command voltages over a symmetrical span of ±10 V, enabling direct connection to speed or pressure regulators. Service and diagnostics can also be performed through the RS-232 socket, which operates at up to 115 kBaud for fast parameter access.

Signal reach is generous: the EN2 encoder interface maintains full resolution across shielded cables up to 75 m when sense conductors are present, and the ET real-time link can bridge 100 m between distributed drive cabinets. High impedance, specified at 1000 kΩ, on the MA1 inputs prevents measurable loading of external transducers, while the corresponding outputs supply 10 mA for actuator cards. Event capture inputs tolerate pulse widths no longer than 100 ms, a constraint that preserves timing accuracy in fast sequencing applications. Analog I/O expansion is available when additional process channels are required.
