Product Description:

The CSH02.1B-CC-EC-CN-L3-DA-NN-FW is a motion and automation controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It provides centralized processing for multi-axis machines, linking real-time fieldbus traffic with drive feedback to execute trajectory calculations, I/O handling, and safety interlocks. Installed in a control cabinet, the unit distributes reference data to servos, collects encoder information through its multi-channel interface, and supervises torque-free shutdown pathways required in modern production cells.

The controller accepts a supply of 24 V DC and draws a base load of 17 W, so cabinet power sizing can remain modest. Command values leave the unit through an analog stage that resolves to 24 mV per increment, while incoming process variables are captured with 14-bit precision to support fine loop tuning. Current vectors in connected drives are refreshed every 62.5 µs, allowing tight torque regulation, and the integrated SERCOS III master moves axis data over fiber or copper in parallel with a CANopen fieldbus. Digital and analog expansion cards plug into three backplane positions, and encoder feedback from resolvers, EnDat, or BiSS devices is accepted on the Multi-Encoder port without external converters.

Higher-level interpolation is executed on a 250 µs position cycle so coordinated groups stay synchronized despite load changes. Up to 3 optional slots accommodate extra digital or analog I/O or a second communication stack without increasing the footprint. The controller uses a Safe Torque Off channel that removes drive enable lines while leaving fieldbus diagnostics active, and it can source up to 350 mA for confirmation circuitry. It supports pick-and-place gantries, packaging formers, and modular transfer stations that require deterministic motion and certified shutdown behavior.
