Product Description:

The CSH02.1B-CC-EC-PB-S4-DA-NN-FW controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It serves as the central motion unit in automated equipment, generating tightly timed setpoints that coordinate drives, sensors, and auxiliary field devices. By integrating high-speed control loops with deterministic networking, the device links the PLC layer to the servo hardware so that path, speed, and safety commands are issued without external gateways. That arrangement helps the machine respond quickly to changing loads and synchronized sequences. This architecture reduces wiring complexity and shortens startup.

Primary field communication is handled by the Sercos III Master interface. It circulates telegrams every 250 µs, while internal current loops close in 62.5 µs and velocity loops refresh in 125 µs to keep motor torque stable. A secondary channel based on PROFIBUS allows legacy panels or I/O stations to exchange process data without occupying the real-time bus. Functional safety is provided through Safe Motion, enabling safe stop, safe limited speed, and safe direction functions directly inside the controller. Position loops settle in 250 µs, and the multi-encoder interface accepts incremental or absolute feedback formats. Digital or analog I/O extension cards can be added through spare backplane connectors, which helps adapt the unit to machine layouts that need additional local signals.

At the hardware layer, the controller governs a single mechanical chain, so it is optimized for applications that require only 1 axis of coordinated motion. The base board presents three analog inputs, two analog outputs, and 5 configurable lines that can be set as digital or analog resources. Standard wiring is simplified by 11 discrete digital inputs and two probe inputs reserved for fast registration edges. For future expansion, the housing contains 3 optional slots that accept additional communication or memory modules. These resources suit single-axis gantries, feeders, and tooling heads where synchronized motion and fast signal capture are important, and they leave room for later interface growth without changing the control platform.
