Product Description:

The CSH01.1C-ET-EN2-EN2-NNN-S2-S-NN-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is a modular motion-control board that fits into IndraDrive inverter racks to coordinate axis feedback, fieldbus traffic, and certified safety functions for automated machinery. By combining encoder handling, analog I/O, and Multi-Ethernet connectivity on one card, the device shortens cabinet wiring and supports synchronous control of packaging equipment, gantry systems, and other multi-axis cells.

The board draws a base input of 7.5 W, which represents both its steady thermal load and the sizing of cabinet power supplies. Its analog output stage can source up to 1 mA or drive a reference of 5 V, permitting speed or torque commands to external drives that still rely on analog signaling. Fast fieldbus exchange is handled through the 100Base-TX standard, and protocol selection is handled by the built-in Multi-Ethernet stack so EtherNet/IP, PROFINET, or EtherCAT can be used without extra hardware. A start-up surge of 4 A must be accommodated by the control supply, and the network is accessed through an RJ-45 8-pin connector. Discrete safeguarding interfaces include a door-lock contact rated 24 VDC at 1 A and a dedicated safety output of 24 V at 0.5 A, both governed by the Safe Motion technology layer.

Encoder feedback is accepted on two EnDat 2.1, 1 Vpp, or 5 V TTL ports that are energized by a 5.0 V rail capable of supplying 350 mA. During power-up, the inrush event lasts 100 ms, so upstream breakers must tolerate that pulse width. The separate Ethernet switch section consumes 2.2 W, and each EN2 extension interface adds 6 W. Safe Motion functions monitor velocity and position in real time, using dedicated logic within the controller to cut the 24 V safety line if set limits are exceeded.
