Product Description:

The CSH02.5B-CC-EC-ET-NN-EC-NN-NW is a motion and logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It operates as the Sercos III master in multi-axis drive systems, sending deterministic setpoints and collecting feedback from connected drives and encoders. Three factory-installed interface slots are arranged as Multi-Encoder, Multi-Ethernet, and Multi-Encoder, so the unit can process incremental or absolute feedback while also providing standard Ethernet access for diagnostics. It is intended for automated machinery that requires synchronized motion and integrated logic in one controller.

Real-time processing is supported by 11 digital inputs for fast signal capture and 2 analog outputs for proportional control of external actuators. The current regulator runs on a 62.5 µs current loop, the velocity regulator updates on a 125 µs velocity loop, and the position interpolator refreshes on a 250 µs position loop. These fixed update periods help keep following error low and maintain phase alignment between axes during coordinated motion. Even under concurrent I/O activity, kernel-level scheduling preserves loop timing, and hardware watchdogs can force a controlled stop if any cycle overruns.

Panel integration is aided by 3 analog inputs, 5 configurable digital I/O points, and an Ethernet channel rated at 100Base-TX through an RJ-45, 8-pin port. The controller has a compact housing with only 103 mm depth, along with a width of 49.5 mm and a height of 241 mm, which helps in high-density rail layouts. This arrangement allows local analog and digital signals to be connected directly to the controller without a separate interface module. Safety technology is not equipped, so external STO hardware is required where that function is needed. The unit ships without a control panel, and application software is loaded through the service port before operation.
