Product Description:

The CSH01.3C-ET-NNN-NNN-CCD-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. The board functions as the central motion and I/O processor inside an IndraDrive unit, translating machine commands into real-time axis signals for industrial automation equipment. By combining servo regulation with local interface handling, the module reduces cabinet space and wiring while maintaining deterministic response in packaging lines, gantry axes, and similar applications. It is installed in the drive's control slot and communicates with supervisory PLCs over high-speed networks.

The analog subsection supplies 2 analog outputs and one analog input. Each output is refreshed in 10 µs, so torque or velocity setpoints can be updated at a high rate during operation. Signal granularity is 19.5 mV/inc, which matches the resolution used by IndraDrive power stages. With a rated digital line capacity of 500 mA, the card can switch inductive loads such as contactors without external relays. Field communication is handled through Multi-Ethernet, enabling EtherNet/IP, PROFINET, EtherCAT, and SERCOS III identities on the same hardware, while four combined I/O points allow flexible local sensing and cross-communication to neighboring drives through the CCD optical link.

A group of digital outputs shares a ceiling of 1000 mA, allowing parallel activation of solenoid valves or brake releases. The single relay contact is wired as one normally open contact for higher-voltage signaling. For probe functions, the controller sources 3 mA at 24 V and timestamps rising edges as narrow as 4 µs to support precise position capture. The outputs are designed for loads down to 5 kΩ, preserving linearity across the full range, and serial diagnostics are available through an RS-232 port that streams at up to 115 kBaud over cables as long as 15 m. The relay contact and probe input support machine interlocks and capture tasks without requiring a separate interface card.
