Product Description:
The CSB01.1C-ET-ENS-MEM-L2-S-NN-FW is a control section used within the Bosch Rexroth Indramat CSB Drive Controllers series. As a plug-in automation module, it governs the current and motion loops of connected servo axes and exchanges data with higher-level PLCs over multiple Ethernet topologies. By combining signal processing and network routing inside a single board, the unit simplifies cabinet layouts and supports deterministic drive regulation for packaging, printing, and material-handling machines.
Its built-in communication layer is realized through a Multi-Ethernet interface, so PROFINET, EtherNet/IP, or standard TCP/IP traffic can run without additional option cards. The current loop refreshes every 125 µs, enabling tight torque control even on fast servo axes. Physical network access is presented on a pair of RJ-45 (8-pin) jacks wired for the 100Base-TX standard; these connect at the labeled X24 and X25 sockets, while legacy HMI or service tools can still use the onboard RS-232 serial port. These connections allow deterministic fieldbus exchange, diagnostic streaming, and fallback maintenance access without extra wiring complexity.
The unit has a depth of 103 mm, a width of 49.5 mm, and a height of 241 mm, so the control section fits beside power modules on a 300 mm cabinet rail. Internal logic draws only 8 W from the control backplane, and all circuits operate from a stabilized DC 24 V feed that is common to Indramat drive stacks. A short inrush pulse of 110 ms must be tolerated by the auxiliary supply, after which steady-state demand remains low, allowing small UPS units to ride through brief mains disturbances. These dimensions and the modest power profile allow multiple CSB sections to be clustered while maintaining proper convection paths and service clearances inside densely populated enclosures.
