Product Description:

The CSH01.3C-C0-EN2-NNN-CCD-NN-S-NN-FW controller is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This plug-in control section fits into IndraDrive drive units and executes closed-loop command processing for servo axes, I/O handling, and fieldbus communication in industrial automation cells. By combining motion calculations, real-time safety reactions, and network routing on one board, the module coordinates motors, sensors, and higher-level PLCs, allowing compact machine tools and material-handling lines to synchronize motion without separate standalone controllers.

The board draws a base idle power of 8.5 W, while its dedicated EN2 encoder sub-module adds another 6 W when active. The board has 2 differential analog channels for feedback scaling. Digital switching points can source up to 500 mA per output, so external relays or LEDs can be driven directly. Network cross-communication follows the IEEE 802.3 standard, allowing deterministic data exchange over an internal 100 Mbps backplane. These values indicate the thermal load, wiring limits, and available interface range the drive must accommodate.

An RS-232 diagnostic port reaches transfer rates of 115 kBaud over cable runs up to 15 m, enabling parameter access during setup. For PWM control of power stages, the control signals can toggle at a peak switching frequency of 16 kHz, supporting quieter motor operation. A typical inrush current of 4 A occurs for up to 100 ms, so upstream supplies must handle that transient. The EN2 circuitry operates at 5.0 V with 35 Ω load resistance, and the separate CCD interface consumes only 1 W. Position feedback is accepted through EnDat 2.1, 1 Vpp, or 5 V TTL encoders, while the engineering port uses 100Base-TX for real-time trace acquisition and controller updates.
