Product Description:
The CSH02.1B-CC-EC-ET-SB-NN-NN-FW is a compact motion and logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on the control section of Rexroth drive stacks, it processes axis commands, supervises safety states, and distributes synchronized setpoints to connected power sections. The module serves as the coordination point in multi-axis automation lines, allowing deterministic interpolation and real-time diagnostics that are essential for pick-and-place, winding, and palletizing equipment. Its role in the drive stack makes it suitable for applications that require tightly coordinated motion across several connected axes.
Its electronics draw a regulated DC 24 V supply and require only 17 W of base power, which minimizes heat inside the cabinet. Motion data are exchanged through a Sercos III master interface that refreshes every 250 µs, keeping phase alignment between the controller and slave drives. The torque-producing loop updates at 62.5 µs, while position references are recalculated at the same network interval to maintain interpolation accuracy. Two probe inputs capture external position marks, and the analog monitor channel provides 24 mV per increment resolution for oscilloscope-class signal tracing. A multi-encoder interface permits connection of SSI, EnDat, or resolver feedback, and the 1 ms maximum inrush pulse rating helps protect upstream 24 V supplies during power-up.
Application wiring can be routed directly to the board through 11 digital inputs, two relay outputs rated for 1 × 10⁸ mechanical cycles, and three optional slots that accept fieldbus or memory extensions. For plant networks, the integrated Multi-Ethernet port supports EtherNet/IP, PROFINET, or EtherCAT without additional hardware. Axis safeguarding is handled by the Safe Motion Bus, which exchanges safety positions with associated drives independently of the user program. Fast following-error suppression is aided by the velocity loop, which updates every 125 µs, allowing tight contouring even when the controller is managing multiple high-speed axes. This combination of I/O, network connectivity, and safety communication supports use in compact but demanding automation systems.
