Product Description:

The CSH01.1C-PB-EN2-NNN-MD2-S2-S-NN-FW controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit serves as the control section in modular drive systems, coordinating motion axes and peripheral devices inside automated assembly lines, material-handling cells, and packaging machines. By accepting fieldbus commands and managing encoder feedback, it translates high-level machine instructions into precise drive signals, forming the interface between supervisory logic and servo power stages. This arrangement allows motion commands, feedback evaluation, and machine responses to be handled within one control platform for coordinated axis behavior.

During power-up, the controller draws a base inrush current of 4 A, and that surge is limited to 100 ms so upstream supplies do not need excessive reserve capacity. Once steady-state operation is reached, its base power consumption levels off at 7.5 W, allowing dense cabinet layouts with minimal thermal loading. Communication with higher-level PLCs is handled through PROFIBUS-DP. When configured for maximum throughput, the integrated interface supports a bus speed of 12 MBaud, enabling synchronous exchange of setpoints, status words, and diagnostics in real time.

For local feedback and I/O handling, the board offers an encoder port that accepts the mixed-signal format EnDat 2.1 / 1 Vpp / 5 V TTL, giving it compatibility with both absolute and incremental transducers used on servo motors and linear stages. Machine interlocking and sensor evaluation are achieved through 16 digital inputs, while a matching set of digital outputs can actuate contactors or indicator circuits. When driving external relays, the output stage tolerates a load of DC 24 V / 1 A, and the integrated safety layer provides Safe Motion functions that stop movement within controlled limits. This supports safer machine response when an operating condition requires motion to be reduced or removed.
