Product Description:

The CSH02.1B-CC-EC-EM-NN-DA-NN-FW is a modular motion and I/O controller built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in multi-axis cells, the unit issues position, speed, and process commands to servo drives, sensors, and actuators. Acting as the real-time coordination node within an automation line, it uses embedded control logic to synchronize mechanical movement, collect analog feedback, and pass deterministic data to a higher-level PLC or factory network. This allows one controller to coordinate motion and process I/O from a single platform. Its compact format fits standard control cabinets and helps reduce wiring density across the panel.

All low-voltage electronics are powered from a 24 V rail, keeping logic isolated from line power. Each analog output refreshes in 250 µs and can drive equipment with a burden as low as 2 kΩ, while the step size is 24 mV per increment. Incoming current signals use a 300 Ω termination and are digitized with 12-bit resolution, and the resolver channel uses the same resolution for rotor angle capture. Voltage inputs pass frequencies up to 1.3 kHz before a 14-bit converter samples the waveform, and cyclic data exchange with drives is handled by a Sercos III master. The multi-encoder interface also accepts EnDat, SSI, and Hiperface formats.

Base consumption of the controller is 17 W, so cabinet cooling requirements stay moderate during normal operation. During power-up, the supply sees an inrush of <5 A, which helps prevent nuisance trips on auxiliary breakers. Motor feedback stations can be placed up to 40 m away when shielded cable is used, giving more freedom in large machine layouts. Common-mode interference on voltage inputs is rejected by 50 dB, helping preserve measurement accuracy at the analog interface.
