Product Description:

The CSH01.2C-SE-ENS-NNN-CCD-S1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive modular rack, this unit executes motion profiles, processes feedback, and relays fieldbus commands so servo axes follow programmed trajectories with millisecond accuracy. By combining network communication, encoder evaluation, and integrated safety circuitry, it acts as the central coordinator for packaging lines, metal-cutting centers, and material-handling stations that demand synchronized multi-axis behavior. In the rack, the control section manages axis coordination while the associated power section supplies the motor current.

Its base electronics draw only 8.5 W, so minimal heat is introduced into the cabinet. Drive commands travel over the SERCOS II real-time bus, and the controller supports transmission rates up to 16 MBaud to preserve tight velocity and position loops. A dedicated encoder output delivers DC 11.6 V at up to 300 mA, allowing direct supply of IndraDyn and HIPERFACE feedback devices without external power modules. The Ethernet-based engineering interface supports parameter setup and diagnostics, while an RS-232 serial port remains available as a service channel for legacy tools.

For plant-wide coordination, the card can function as a SERCOS III Master, exchanging axis and process data over media that comply with the IEEE 802.3 physical layer standard. Its Safety Technology I/O block accepts dual-channel inputs rated at 24 V / 3 mA and sources outputs at 24 V / 0.5 A, validating each signal within a maximum pulse width of 100 ms for stop-category functions. A typical inrush current of 4 A occurs at power-up, so upstream protection gear must accommodate that brief load. The safety and communication interfaces let the module exchange motion data while monitoring safe input and output signals in the same slot.
