Product Description:
The CSB02.1B-ET-EC-PB-S4-NN-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. It mounts on matching power modules to govern servo or induction axes in industrial automation. Acting as the command layer, it exchanges setpoints, feedback, and diagnostic messages with higher-level PLCs and coordinates motion sequences, safety states, and fieldbus communication through its integrated network ports.
For signal processing, the control section supplies 11 digital inputs that accept 24 V logic from limit switches, proximity sensors, or emergency stops. Alongside them are 5 configurable digital I/O channels, and each channel can be set as an input or an output to match application-specific handshake lines. Two ±10 V references leave the board through 2 analog outputs, allowing speed or pressure commands for external actuators. Position feedback is handled by a Multi-encoder interface that automatically detects EnDat, Hiperface, BiSS-C, or SSI signals while routing power on the internal 15-pin motor-encoder connector. Deterministic messaging over copper or fiber adheres to IEEE 802.3, so cycle times remain consistent when the device operates on gigabit or 100 Mb industrial Ethernet rings.
The fieldbus node includes PROFIBUS-DP access through a 9-pin D-Sub, and the Multi-Ethernet port can be switched among Sercos III, EtherCAT, EtherNet/IP, or PROFINET IO without hardware changes. Three optional slots remain free for I/O or technology cards while preserving the integrated safety package identified as Safe Motion for STO, SS1, and safe limited speed functions. For feedback devices, the board provides a 6 W encoder supply that supports high-resolution optical encoders on long cables. Resolver inputs are not offered, so digital encoders must be selected. Compatibility with HCS02, HCS03, HCS04, HMS01, and HMS02 power sections allows the same control section to be used across different current classes.
