Product Description:

The CSH01.2C-PB-EN2-ENS-CCD-S1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power sections, the unit generates position, velocity, and torque commands for servo drives used in packaging, printing, and material-handling lines. It provides the logic layer between higher-level PLCs and the inverter stage, allowing deterministic command execution, real-time feedback processing, and integrated functional safety within distributed automation architectures.

In operation, the controller accepts a logic supply of 24 V DC. This low-voltage rail powers the microprocessor and I/O circuitry while limiting energy dissipation to a basic draw of only 8.5 W. When input power is applied, the module can momentarily pull a typical inrush of 4 A, so upstream power supplies must be sized accordingly. Application programs and diagnostic data are loaded through the Ethernet-based engineering interface, while cyclic process data are exchanged over the master fieldbus PROFIBUS-DP for deterministic plant communication. Together with the compact 49.5 mm width and 103 mm depth, these electrical characteristics facilitate dense cabinet layouts.

Motion signals leave the section as PWM commands up to 8 kHz, and the internal pulse-forming logic supports widths as long as 100 ms for time-critical safety tasks. Encoder channel X4 reads EnDat 2.1, 1 Vpp, or 5 V TTL feedback from a 5 V supply, while X8 accepts IndraDyn, Hiperface, 1 Vpp, or TTL feedback powered by 12 V, enabling mixed-sensor installations and Cross Communication Drives synchronization. Hardware watchdogs and digital inputs tied to Safety Technology I/O allow immediate STO or SS1 reactions. The overall height of 241 mm keeps the controller within standard 300 mm control-cabinet rails.
