Product Description:

The CSH02.5B-CC-EC-ET-L3-EM-NN-FW is a motion and logic controller from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. It coordinates drive axes and peripheral devices by combining high-speed field communication with local signal processing. This arrangement provides deterministic control for multi-axis machines and automated cells.

The unit supplies 3 analog inputs for tasks such as potentiometer speed references or sensor feedback. Two output channels deliver a swing of ±10 V, and each step is quantized at 6 mV/incr; this resolution allows fine voltage trimming when commanding external amplifiers. There are 2 analog outputs in total, complemented by 11 digital inputs that accept proximity switches or PLC status lines. Five of those digital points are user-configurable as sourcing or sinking to match plant wiring. The front panel also offers two probe inputs for precise edge capture during registration moves, and encoder emulation on Interface 4 allows downstream drives to follow a virtual master. Three optional slots accommodate additional cards, and the controller mates electrically with the HMU05 power section to obtain regulated logic supply and internal diagnostics.

The embedded Ethernet terminal supports 100Base-TX signaling through an RJ-45, 8-pin connector, giving access to parameter servers and higher-level networks. Axis coordination is executed over a deterministic SERCOS III master channel, which moves process data in tightly timed cycles. Plant-wide lockout requirements are met by the integrated STO (Safe Torque Off) function; when the safety relay opens, motor power is removed without relying on software states. Two probe inputs let the motion kernel time-stamp encoder positions relative to external marks. The three optional slots can host fieldbus couplers or expanded memory so the controller can be adapted to more complex machines.
