Product Description:

The CSH02.5B-CC-EC-NN-S4-NN-NN-NW is a motion-control hardware unit produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. As a central axis controller, it coordinates servo drives and field devices, linking machine logic with power electronics. In automated cells, the unit generates command trajectories, reads feedback from encoders, and passes synchronized data to the drive bus for multi-axis packaging or material handling lines. It relies on an integrated communication master to manage timing across components and provides onboard I/O for direct sensor wiring, which helps reduce cabinet space.

Local signal processing starts with 3 analog inputs for velocity, torque, or process voltages, while 2 analog outputs can retransmit status variables to external meters or PLC cards. The controller also integrates 11 digital inputs for high-speed edge detection, and the maximum pulse width is 1 ms so short triggers can be captured without extra hardware. All circuits run from a DC 24 V control supply that keeps logic active even when the main drive link is de-energized. Network coordination is handled by the Sercos III Master, and a Multi-Encoder Interface supports incremental, absolute, and EnDat feedback devices, although resolver signals are not accepted. Five configurable digital I/O points plus two probe inputs provide flexible interlocking.

At startup the controller draws <5 A, easing selection of protective low-voltage supplies. Functional safety is provided through Safe Motion, enabling certified stop and velocity monitoring without separate relays. The integrated power section is identified as HMU05 and can be expanded by three optional slots for fieldbus couplers or memory modules. The unit also includes two current input channels for diagnostic monitoring of connected axes.
