Product Description:

The CSH01.1C-SE-ENS-EN2-MD2-NN-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat and delivered as part of the CSH Advanced Controllers series. This module installs in Rexroth drive assemblies and acts as the primary processing unit that links power electronics with higher-level automation networks, coordinating axis motion, process timing, and local I/O tasks on the machine. It is intended for industrial automation cells where deterministic communication and compact control hardware are required. Its placement beside the drive stack allows logic handling, feedback evaluation, and fieldbus communication to remain close to the power stage instead of being moved to a separate PLC rack.

Real-time data exchange uses SERCOS II, and the board runs at 16 MBaud to support multi-axis communication with short update cycles. The analog path has an input impedance of 160 kohm, which reduces loading on external transducers, while the output stage provides 5 V for signal generation. A base power draw of 7.5 W helps limit cabinet heat during normal operation, and the sixteen transistor drivers can each supply 0.5 A, allowing local devices such as contactors or indicator lamps to be switched directly. Continuous status is shown on the single-line display, and the SSI evaluation circuit supports synchronous serial feedback for encoder processing.

At power-up, the module withstands an inrush current of 4 A before settling to its nominal draw, and the encoder supply rails provide 12 V for the primary sensor and 5 V for the secondary line. Encoder 2 accepts EnDat 2.1, 1 Vpp, or 5 V TTL formats and limits pulse widths to 100 ms when marker signals are captured. The Md2 expansion provides 16 digital inputs and an equal number of sourcing outputs, so local switches, valves, or small actuators can be wired directly to the control section. The module has no integrated safety technology, so external safety relays must interrupt the power stage when required.
