Product Description:

The CSH01.3C-PB-ENS-MEM-CCD-S2-S-NN-FW is an automation controller from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Within a multi-axis drive cabinet, this unit handles real-time motion tasks and fieldbus coordination for servo drives, I/O nodes, and safety devices. Its role in industrial automation is to execute axis commands, evaluate feedback, and exchange data with higher-level PLCs so that machine cycles stay synchronized and deterministic.

The controller draws only 8.5 W at its base operating state, allowing dense electrical panels with minimal thermal load. Command traffic to drives and remote terminals is carried on PROFIBUS-DP, which supports cyclic telegrams for position, torque, and diagnostic data. Integrated encoder power is available at 500 mA and 11.6 V, so absolute and incremental feedback devices can be supplied directly from the board. Standard encoder evaluation logic processes both formats without additional option cards. During power-up, the controller can draw up to 4 A of inrush current, which should be considered for branch-circuit protection. The engineering interface uses 100Base-TX, enabling parameter transfer over standard Ethernet. A PROFIBUS repeater output may be loaded to 75 mA, and MEM serial lines may extend up to 40 m while maintaining reflected-wave integrity for distributed axis modules.

The worst-case inrush event lasts 100 ms, after which internal regulators settle and MEM timing reaches its rated 1 MHz clock for synchronous drive data. Cross-controller communication follows the IEEE 802.3 standard, permitting deterministic peer messaging when multiple CSH units share motion tasks. The integrated safety layer provides Safe Motion, allowing certified monitoring of speed and position without external relays. Distributed axis groups can use single-cable feedback layouts while keeping motion data coordinated through the controller.
