Product Description:

Bosch Rexroth Indramat designs the CSH02.5B-CC-EC-PB-S4-EM-NN-NW as part of the CSH Advanced Controllers series. This control section is inserted into IndraDrive servo platforms to process motion commands, manage fieldbus communication, and deliver analog reference signals to downstream power stages. Within an automation cell, the unit acts as the central coordinator, converting PLC instructions into synchronized axis trajectories while maintaining deterministic timing for packaging, material handling, and assembly machinery. Its role is focused on command processing and coordination, while the matched power stage handles motor current delivery.

The controller’s analog interface is dimensioned for process control tasks that require precise voltage references. Each channel can drive capacitive loads up to 750 nF without signal distortion and must see an external impedance of at least 2 kΩ to sustain linear swing. Resolution is provided in steps of 6 mV/incr, allowing fine adjustment of torque or velocity setpoints. The permissible analog range extends from -10 V to 10 V, so both unipolar and bipolar command schemes are supported. This arrangement allows the controller to interface directly with servo amplifiers, proportional valves, or other analog-driven actuators used in closed-loop machinery.

Channel refresh completes within 250 µs, aligning the analog output cycle with high-speed trajectory calculations. For encoder feedback, the board supplies up to 12 W of power and holds the 12-volt rail at 12.3 V maximum to accommodate absolute or incremental transducers. Profibus connectivity is optimized for long network runs, and the bus driver presents a characteristic impedance of 350 Ω to minimize reflections. The integrated repeater draws only 75 mA from the internal 5 V logic supply, which helps the controller support feedback handling and network communication in multi-axis installations.
